Over the past half a century many countries have witnessed a rapid fall in total fertility rates, particularly in the world's most advanced economies including the industrial powerhouses of Eastern Asia and Europe. Such nations have now passed through the first and second demographic transitions and are currently exhibiting fertility rates well below the replacement threshold of 2.1, with no sign of recovery. This paper examines the factors responsible for driving these demographic transitions and considers their impact on both fertility and fecundity (our fundamental capacity to reproduce). I argue that because the first demographic transition was extremely rapid and largely driven by socioeconomic factors, it has had no lasting impact on the genetic/epigenetic underpinnings of human fecundity. However, the second demographic transition will be different. A series of conditions associated with low fertility societies, including relaxed selection pressure for high-fertility genotypes, the indiscriminate use of assisted reproductive technologies to treat human infertility, and environmental contamination with reproductive toxicants, may impact our genetic constitution in ways that compromise the future fecundity of our species. Since any fundamental change in the genetic foundations of human reproduction will be difficult to reverse, we should actively pursue methods to monitor human fecundity, as sub-replacement fertility levels become established across the globe.

Procreative obligations are often discussed by evaluating only the consequences of reproductive actions or omissions; less attention is paid to the moral role of intentions and attitudes. In this paper, I assess whether intentions and attitudes can contribute to defining our moral obligations with regard to assisted reproductive technologies already available, such as preimplantation genetic diagnosis (PGD), and those that may be available in future, such as reproductive genome editing and ectogenesis, in a way compatible with person‐affecting constraints. I propose the parent–child relationship argument, which is based on the moral distinction between creating and parenting a child. Hence, I first argue that intentions and attitudes can play a role in defining our moral obligations in reproductive decisions involving PGD. Second, I maintain that if we accept this and recognize reproductive genome editing and ectogenesis as person‐affecting procedures, we should be committed to arguing that prospective parents may have moral reasons to prefer reproduction via such techniques than via sexual intercourse. In both cases, I observe an extension of our procreative responsibility beyond what is proposed by the consequentialist person‐affecting morality. [ABSTRACT FROM AUTHOR]

Background: In 2020, SARS-CoV-2 and the COVID-19 pandemic had a huge impact on the access to and provision of ART treatments. Gradually, knowledge of the virus and its transmission has become available, allowing ART activities to resume. Still, questions on the impact of the virus on human gametes and fertility remain.Objective and Rationale: This article summarizes published data, aiming to clarify the impact of SARS-CoV-2 and the COVID-19 disease on human fertility and assisted reproduction, as well as the impact of vaccination, and from this, provide answers to questions that are relevant for people contemplating pregnancy and for health care professionals.Search Methods: PUBMED/MEDLINE and the WHO COVID-19 database were searched from inception to 5 October 2022 with search terms focusing on 'SARS-CoV-2' and gametes, embryos, reproductive function, fertility and ART. Non-English studies and papers published prior to 2020 were excluded, as well as reviews and non-peer reviewed publications. Full papers were assessed for relevance and quality, where feasible.Outcomes: From the 148 papers included, the following observations were made. The SARS-CoV-2-binding proteins, angiotensin-converting enzyme 2 (ACE2) and type II transmembrane serine protease (TMPRSS2), are expressed in the testis, but co-expression remains to be proven. There is some evidence of SARS-CoV-2 RNA in the ejaculate of COVID-19 patients with severe disease, but not in those with mild/moderate disease. SARS-CoV-2 infection can impair spermatogenesis, but this seems to resolve after one spermatogenic cycle. Testosterone levels seem to be lower during and after COVID-19, but long-term data are lacking; disease severity may be associated with testosterone levels. COVID-19 cannot be considered a sexually transmitted disease. There is no co-expression of ACE2 and TMPRSS2 in the myometrium, uterus, ovaries or fallopian tubes. Oocytes seem to have the receptors and protease machinery to be susceptible to SARS-CoV-2 infection; however, viral RNA in oocytes has not been detected so far. Women contemplating pregnancy following COVID-19 may benefit from screening for thyroid dysfunction. There is a possible (transient) impact of COVID-19 on menstrual patterns. Embryos, and particularly late blastocysts, seem to have the machinery to be susceptible to SARS-CoV-2 infection. Most studies have not reported a significant impact of COVID-19 on ovarian reserve, ovarian function or follicular fluid parameters. Previous asymptomatic or mild SARS-CoV-2 infection in females does not seem to negatively affect laboratory and clinical outcomes of ART. There are no data on the minimum required interval, if any, between COVID-19 recovery and ART. There is no evidence of a negative effect of SARS-CoV-2 vaccination on semen parameters or spermatogenesis, ovarian function, ovarian reserve or folliculogenesis. A transient effect on the menstrual cycle has been documented. Despite concerns, cross reactivity between anti-SARS-CoV-2 spike protein antibodies and Syncytin-1, an essential protein in human implantation, is absent. There is no influence of mRNA SARS-CoV-2 vaccine on patients' performance during their immediate subsequent ART cycle. Pregnancy rates post-vaccination are similar to those in unvaccinated patients.Wider Implications: This review highlights existing knowledge on the impact of SARS-CoV-2 infection or COVID-19 on fertility and assisted reproduction, but also identifies gaps and offers suggestions for future research. The knowledge presented should help to provide evidence-based advice for practitioners and couples contemplating pregnancy alike, facilitating informed decision-making in an environment of significant emotional turmoil.

For females without a functioning womb, the only way to become a biological parent is via assisted gestation—either surrogacy or uterus transplantation (UTx). This paper examines the comparative impact of these options on two types of putative 'womb‐givers': people who provide gestational surrogacy and those who donate their uterus for live donation. The surrogate 'leases' their womb for the gestational period, while the UTx donor donates their womb permanently via hysterectomy. Both enterprises involve a significant degree of self‐sacrifice and medical risk in order to enable another person(s) to become a parent by either providing gestational labour or enabling the other person to undertake gestation themselves. In this paper, we explore the burdens and the benefits from the perspective of the womb‐giver in order to inform ethical debate about assisted gestation. This is a perspective that is often neglected in the bioethical discourse. With both surrogacy and UTx, when success follows the womb‐giver's sacrifice, the key benefit is delivered to the intending parent(s), but as this article examines, the womb‐giver may also enjoy some unique (relational) benefits as a result of their sacrifice. Ultimately, the choice of how a womb‐giver lends assistance in gestation will impact on their bodily autonomy; some will prefer to carry a pregnancy and others to donate their uterus. We argue that the perspective of the womb‐giver is crucial and thus far has not been afforded sufficient consideration in ethical discussion. [ABSTRACT FROM AUTHOR]

Internationally, there is considerable inconsistency in the recognition and regulation of children's genetic connections outside the family. In the context of gamete and embryo donation, challenges for regulation seem endless. In this paper, I review some of the paths that have been taken to manage children' being closely genetically related to people outside their families. I do so against the background of recognising the importance of children's interests as moral status holders. I look at recent qualitative research involving donor‐conceived people and borrow their own words to make sense of a purported interest to know (of) their close genetic ties. I also review ways in which gamete donation may have facilitated new kinds of kinship, which are at the same time genetic and chosen. In short, in this paper, I explore what meaning there could be in genetic connections that is not about parenthood. Further, I argue that the focus on parenthood in previous work in this area may be detrimental to appreciating some of the goods that can be derived from close genetic connections.

Assisted reproduction often involves biological contributions by third parties such as egg/sperm donors, mitochondrial DNA donors, and surrogate mothers. However, these arrangements are also characterised by a biological relationship between the child and at least one intending parent. For example, one or both intending parents might use their own eggs/sperm in surrogacy, or an intending mother might conceive using donor sperm or gestate a donor embryo. What happens when this relationship is absent, as in the case of 'double‐donor surrogacy' arrangements (DDS)? Here, a child is conceived using both donor eggs and sperm, carried by a surrogate, and raised by the commissioning parents. In this paper, I critically examine proposals to allow DDS in the United Kingdom, and the intentionalist justification for treating this practice distinctly (morally and legally speaking) from private adoption. I argue that the intentionalist approach cannot plausibly justify such a distinction and that other approaches to moral parenthood are also unlikely to succeed. [ABSTRACT FROM AUTHOR]

Novel forms of assisted gestation—uterus transplantation and artificial placentas—are highly anticipated in the ethico‐legal literature for their capacity to enhance reproductive autonomy. There are also, however, significant challenges anticipated in the development of novel forms of assisted gestation. While there is a normative exploration of these challenges in the literature, there has not yet, to my knowledge, been empirical research undertaken to explore what reproductive rights organisations and advocates identify as potential benefits and challenges. This perspective is invaluable. These organisations/individuals have an awareness not only of the needs of individuals but also of the political landscape in which regulatory decisions are made and which individuals navigate when seeking reproductive assistance. In this study, data was generated from two semi‐structured focus groups (n = 11). Reflective thematic analysis was used to examine the views raised by study participants in these focus groups. This paper explores two of the themes constructed in the data. First, the equality‐enhancing potential of assisted gestation exploring the multifaceted ways in which assisted gestation has structural benefits for marginalised groups. Second, realising the equality‐enhancing potential of assisted gestation explores the intersecting barriers to access to reproductive technologies and how they may impede the benefits of these technologies in practice. These results can enhance conceptual understanding of the importance of novel forms of assisted gestation and ensure that attention is paid to practical barriers in further normative research.

In this paper, I claim that live uterus donors ought to be considered for the possibility of compensation. I support my claim on the basis of comparable arguments which have already been applied to gamete donation, surrogacy, and other kinds of organ donation. However, I acknowledge that there are specificities associated with uterus donation, which make the issue of incentive and reward a harder ethical case relative to gamete donation, surrogacy, and other kinds of organ donation. Ultimately, I contend that while reimbursement for the costs incurred by live uterus donors should be treated as a necessary ethical minimum, how much further we ought to remunerate uterus donations remains an open question.

This pclper tells a stoyy of shifting normativities, fom tradition to modernity and back, regarding the recognition of legal parenthood in non-traditional families created through crossborder surrogacy. Tbe cross-border nature of the surrogacy is often forced. as most domestic legalfameworks in Europe still restrict the creation of non-traditional families through assisted reproductive technologies. Once back borne, these families struggle to bave birth certificates recognized and establish legal parenthood. Tbe disjuncture between social reality and domestic law creates a situation of legal limbo. In its recent case law. tbe European Court of Human Rights has pusbed for domestic authorities to rect this situation but, at tbe same time, bas filled the legal limbo witb genetic essentialism and allowed for gender discrimination wben recognizing legal parenthood. While giving full effect to a genetic father's foreign birth certificate based on identity and best interests arguments, tbe Court accepts tbat a genetic mother must adopt to establish a legal parent-child relationship. Tbe paper critically addresses this intriguing imbalance. It deconstructs tbe Court's genetic essentialism encouraging a biologically determined view of parenting, which sidelines tbe social (i.e., non-genetically related) parent and contradicts tbe purpose of assisted reproduction to overcome biological barriers. Tbe paper concludes by rejecting tbe gender-discriminatory element of power and control over legal motberbood imposed by tbe procedural step of adoption. [ABSTRACT FROM AUTHOR]

Human uterus transplantation (UTx)—the most radical and experimental of all current forms of assisted reproduction—gives rise to a range of complex ethical questions, including those related to individual safety, risk, and informed consent. I have argued elsewhere that the wider social impacts and implications of UTx provision must form part of a comprehensive ethical analysis. My socio‐moral critique of UTx provision has been responded to with a number of defences of possible public funding of UTx. In this paper I examine a select number of those defences. These include: that UTx provision would address harms and needs that already exist and as such have priority; that UTx provision is fully compatible with the needed reform of the procreative context in which it would be offered; that UTx provision would not necessarily involve legitimation or endorsement of what are widely agreed to be problematic pronatalist or geneticist norms; and that UTx provision is required as a matter of justice and consistency with other practices. Importantly, defenders are not proposing a ceteris paribus justification of UTx provision; nor do my responses to their arguments represent a comprehensive opposition to UTx. Rather, my more limited purpose here is to show that whatever other defences may be given of publicly funded UTx provision, those considered here do not ultimately succeed and therefore do not allay the concerns underpinning the original socio‐moral critique.

Evidence suggests that one reason doctors provide certain interventions in assisted reproductive technologies (ART) is because of patient demand. This is particularly the case when it comes to unproven interventions such as 'add‐ons' to in vitro fertilisation (IVF) cycles, or providing IVF cycles that are highly unlikely to succeed. Doctors tend to accede to demands for such interventions because patients are willing to do and pay 'whatever it takes' to have a baby. However, there is uncertainty as to what moral weight should be placed on patient‐led demands in ART, including whether it is acceptable for such demands to be invoked as a justification for intervention. We address this issue in this paper. We start by elucidating what we mean by 'patient‐led demand' and synthesise some of the evidence for this phenomenon. We then argue that a doctor's professional role morality (PRM) yields special responsibilities, particularly in commercialised healthcare settings such as ART, because of the nature of professions as social institutions that are distinct from markets. We argue on this basis that, while there may be reasons (consistent with PRM) for doctors to accede to patient demand, this is not always the case. There is often a gap in justification between acceding to patient‐led demands and providing contested interventions, particularly in commercial settings. As a result, acceding to demand in such settings needs a strong justification to be consistent with PRM. [ABSTRACT FROM AUTHOR]

Recent achievements in reproductive biomedicine have led to a revolution in infertility treatment. A comprehensive understanding of the current status of reproductive medicine is necessary for the development of a forward-looking plan by health policymakers, based on fundamental requirements. This study is a systematic review of the Scopus database to assess reproductive biomedicine publications within Iran and compared to the rest of the world from 1990 to 2020. The data were categorized by geographical distribution across five continents. National data were assessed in comparison with the world and with neighboring countries. Finally, prominent national research institutes in the field of reproductive biomedicine in Iran were identified, and their contributions to the field highlighted. Of the five continents, the highest number of publications and citations is from Europe (36% publications and 41.5% citations). Corresponding numbers for the other continents are 32 and 33% for America, and 26 and 18.4% for Asia respectively. The remaining publications and citations were from Australia (3.8 and 4.1%) and Africa (2.6 and 3.1%). In a national analysis, the highest-ranking institutes in reproductive biomedicine are in Tehran province (50.9% of all Iranian publications), Shiraz (8.8%), Yazd (7.8%), Isfahan (7.1%), and Tabriz (6.9%). More specifically, Tehran University of Medical Science (15.9%), the Royan Institute (12.2%), Shahid Beheshti Medical University (10.1%), Shahid Sadoughi University of Medical Sciences (6.9%), and Tarbiat Modares University (6.7%) account for more than 50% of all Iranian scientific publications. In recent decades, reproductive biomedical research has grown significantly in Iran. Reviewing publications in this field helps health policy decision makers to monitor the direction of research and adjust investment in the treatment of infertility. In addition, it is necessary to expand and organize inter-organizational and international collaborations to improve the research, gain the benefits of different experiences, and engage in international multicenter studies.

Polycystic ovary syndrome (PCOS) is a lifelong reproductive endocrine disease, which is the most common cause of anovular infertility. Modern medicine mainly treats infertile patients with PCOS by improving living habits, ovulation induction therapy, and assisted reproductive technology (ART), but the effect is not satisfied. Complementary alternative medicine (CAM) has conspicuous advantages in the treatment of PCOS infertility due to its good clinical efficacy, wide mechanism of action, and no obvious adverse reactions, but its safety and effectiveness in the treatment of PCOS infertility have not been proved. Based on the existing clinical and experimental studies, this paper looks for the therapeutic effect and the mechanism behind it, and explores the safety and effectiveness of its treatment in PCOS infertility, in order to provide reference for future clinical treatment and experimental research.

The treatment of unexplained infertility is a contentious topic that continues to attract a great deal of interest amongst clinicians, patients and policy makers. The inability to identify an underlying pathology makes it difficult to devise effective treatments for this condition. Couples with unexplained infertility can conceive on their own and any proposed intervention needs to offer a better chance of having a baby. Over the years, several prognostic and prediction models based on routinely collected clinical data have been developed, but these are not widely used by clinicians and patients. In this opinion paper, we propose a prognosis-based approach such that a decision to access treatment is based on the estimated chances of natural and treatment-related conception, which, in the same couple, can change over time. This approach avoids treating all couples as a homogeneous group and minimizes unnecessary treatment whilst ensuring access to those who need it early. [ABSTRACT FROM AUTHOR]

Worldwide, over 8 million children and adults are conceived following assisted reproductive technologies (ART), and their long-term health is of consequential public health interest. The objective of this paper is to describe the Growing up Healthy Study (GUHS) cohort in detail, publicise it and invite collaboration. Combining the data collected in the GUHS with other cohorts or databases will improve the much-needed knowledge about the effects of ART, and allow for better understanding of the long-term health outcomes of offspring conceived after ART. The GUHS cohort is a prospective observational study of adolescents and young adults conceived after assisted reproductive technologies (ART). It was established to determine if the long-term health of offspring conceived by ART differs from that of the general population. This was investigated by comparing a substantial number of health parameters to those of a representative population of offspring conceived without ART. The n = 303 GUHS participants were born between 1991–2001 in the two fertility clinics operating at the time in Perth, Western Australia, and undertook assessments at ages 14, 17 and 20, replicating the pre-defined study protocols from the reference cohort—the Raine Study. Participants were comprehensively phenotyped through detailed questionnaires, anthropometry, biochemical analyses, as well as age-specific assessments (asthma, atopy, cardiometabolic health, body composition, mental health, thyroid function, epigenetics and vision). To date the GUHS cohort has been used to study the methylation, cardiometabolic, and thyroid profiles, as well as respiratory and mental health. To summarise, the GUHS cohort provides a valuable addition to the limited knowledge of the long-term health outcomes of ART-conceived offspring. [ABSTRACT FROM AUTHOR]

In 2022, the global commercial surrogacy industry was valued at approximately US$14 billion. This paper explores the issue of surrogacy to reveal how international human rights standards and labor laws treat reproduction as work, building on previous scholarship analyzing similar framing at the grassroots level in Mexico. I argue that the failure to recognize surrogacy as labor is rooted in three lacunae: (1) contemporary policies and practices around surrogacy globally pay little attention to the well-being and rights fulfillment of surrogates themselves, particularly the economic rights of surrogates; (2) the stigma of surrogacy as sexualized care work results in neglect of the labor rights of surrogates in mainstream economic rights discourses; and (3) relevant international rights law has not yet addressed the economic rights of surrogates, nor has it effectively articulated the interdependent relationship between economic rights and reproductive rights. Lastly, I discuss where reproductive rights and economic rights overlap in existing human rights conventions and standards and what possibilities these offer for articulating the interdependence of reproductive and economic rights and for advancing the labor rights of surrogates.

Introduction: People living with human immune virus (HIV) are confronting multiple psychosocial and economic issues influenced by the illness. People on anti-retro viral drugs (ART) were at risk for discontinuation of medications during corona viral disease-2019 (COVID-19) pandemic. COVID-19 outbreak made people living with HIV (PLWH) to experience critical challenges and barriers to optimal care. The experience of people living with HIV such as stigma and discrimination, economic problem, psychosocial problem before the emergency of COVID-19 were studied but there is lack of understanding on the lived experience of people living with HIV in the context of COVID-19 in Ethiopia particularly in Tach Gayint. This study aimed to explore the lived experience of people on ART in context of COVID-19 in Tach Gayint district. Methods and materials: Phenomenological study design conducted with 16 study participants from March 12-April 12/2021. Data were collected using in-depth interview using interview guide and digital recorder. The investigator took note in addition to digital record. Interviews were transcribed word for word and translated conceptually. Analysis followed Reading of transcriptions, develop and apply coding, displaying data, data reduction and interpretation. Atlas.ti-7 software used to facilitate analysis. The quality of data was assured by the principles of credibility, dependability, conformability and transferability. Result: The study explored psychological experience, change in social interaction, and economic experience and ART drug interruption as the main themes including other sub-themes. Most participants perceived the severity of COVID-19 on them. Lack of participation in social activities due to fear of contracting and the participants experienced dying and loss of income. This extreme fear pushed some participants to interrupt their daily ART intake especially during lock down period. Personal, familial and community context contributed for these distressing experiences. Conclusion and recommendation: This study reported participants' psychosocial, economic experiences including ART drug interruptions. The government should design policies and interventions to alleviate their personal, household and community problems, which were the caused for the mentioned hostile experiences.

In this paper I argue that current law and policy governing germline genetic modification are overly broad and in fact prohibit medical interventions normally considered unobjectionable. The root of the problem lies in the fact law and policy tend to espouse a near categorical ban on medical interventions that alter germline DNA. However, if we pay close attention to the biological mechanisms at play we see that many standard medical interventions result in alterations to DNA that can be transmitted to future generations. The correct focus of policy and regulation thus ought to be determining which kinds of transmissible genetic modifications ought to be permitted, and not whether they should be permitted at all. Given that the scientific classification of biological structures involved in the inheritance of traits is unlikely to be in itself ethically significant, ethicists ought to develop a definition of 'gene' fit for ethical purposes.

Objective. The aim of this paper was to investigate whether two freeze-thaw cycles before embryo transfer may affect perinatal and neonatal outcomes. Materials and Methods. A total of 8,028 frozen-thawed embryo transfer patients who became pregnant between March 2013 and September 2019 were included. The patients were divided into two groups: the oocyte cryopreservation (OC) group (N = 96) and the control group (N = 7932). Propensity score matching (PSM) was used to adjust the baseline characteristics of the two groups at a proportion of 1 : 4. There were 96 patients in the OC group and 369 patients in the control group after PSM. The pregnancy-related complications and neonatal conditions after delivery of the two groups were compared. Results. The OC group had a higher stillbirth rate (3.1% vs. 0.3%, P = 0.029) than the control group after PSM. Moreover, a slightly higher pregnancy defect rate was found in the OC group. There was no significant difference in the rates of diabetes mellitus, hypertension during pregnancy, cesarean section, multiple births, low birth weight (LBW), or premature birth defects between the two groups. Conclusions. Our findings demonstrate that performing frozen-thawed embryo transfer (FET) with cryopreserved oocytes was associated with a higher rate of stillbirth than FET with fresh oocytes. The incidences of diabetes, gestational hypertension, cesarean section, multiple births, LBW, premature birth, and birth defects of the two groups were not significantly different.

The birth of the world's first genetically edited babies in 2018 provoked considerable ethical outrage. Nonetheless, many scientists and bioethicists now advocate the pursuit of clinical uses of human germline gene editing. Progress towards this goal will require research, including clinical trials where genetically edited embryos are implanted into a woman's uterus, gestated, and brought to term. This paper argues that such trials would likely conflict with the fundamental research ethical requirement of non‐exploitation. This is because they would expose people who are in a vulnerable situation to risks and burdens that are substantial and not obviously offset by compensating benefits. I consider how the potential for exploitation in such trials might be mitigated, arguing that a feasible and justifiable approach is not easily found. If this analysis is correct, there is a significant ethical obstacle on the path towards clinical use of human germline gene editing. [ABSTRACT FROM AUTHOR]

Simple Summary: Gynecological cancers affect many women of reproductive age, necessitating the development of fertility preservation methods to fulfill family planning. Consequently, providing treatment options that preserve fertility in women diagnosed with gynecological cancers has become a crucial component of care for survivors. This leads to improved quality of life, allowing survivors to become mothers even in the seemingly adverse circumstances posed by cancers. However, although there are guidelines on fertility preservation in the context of neoplasms, physicians do not routinely consider it and do not discuss these options with their patients. It is important for patients to be informed about the available options for fertility preservation and to be encouraged to make informed decisions in collaboration with their medical team. Standardized guideline recommendations for onco-fertility should be considered in the future. We explore possible methods that can be employed for obtaining a pregnancy after gynecologic cancer treatment, including more exotic ones like uterine transplant. (1) Background: Currently, an increasing number of women postpone pregnancy beyond the age of 35. Gynecological cancers affect a significant proportion of women of reproductive age, necessitating the development of fertility preservation methods to fulfill family planning. Consequently, providing treatment options that preserve fertility in women diagnosed with gynecological cancers has become a crucial component of care for survivors. (2) Methods: We conducted an extensive search of relevant scientific publications in PubMed and Embase databases and performed a narrative review, including high-quality peer-reviewed research on fertility after being treated for gynecologic cancers, reporting pregnancy rates, birth rates, and pregnancy outcomes in cancer survivors as well as therapeutic options which partially preserve fertility and methods for obtaining a pregnancy in survivors. (3) Discussion: The medicine practiced today is focused on both treating the neoplasm and preserving the quality of life of the patients, with fertility preservation being an important element of this quality. This leads to an improved quality of life, allowing these women to become mothers even in the seemingly adverse circumstances posed by such a pathology. However, although there are guidelines on female fertility preservation in the context of neoplasms, an analysis shows that physicians do not routinely consider it and do not discuss these options with their patients. (4) Conclusions: Advancements in medicine have led to a better understanding and management of gynecological neoplasms, resulting in increased survival rates. Once the battle against these neoplasms is won, the issue of preserving the quality of life for these women arises, with fertility preservation being an important aspect for women who have not yet fulfilled their family planning desires at the time of diagnosis. It is important for patients to be informed about the available options for fertility preservation and to be encouraged to make informed decisions in collaboration with their medical team. Standardized recommendations for onco-fertility into guidelines should be taken into consideration in the future. [ABSTRACT FROM AUTHOR]

Significance: Preparation of a recipient cytoplast by oocyte enucleation is an essential task for animal cloning and assisted reproductive technologies in humans. The femtosecond laser is a precise and low-invasive tool for oocyte enucleation, and it should be an appropriate alternative to traditional enucleation by a microneedle aspiration. However, until recently, the laser enucleation was performed only with applying a fluorescent dye. Aim: This work is aimed to (1) achieve femtosecond laser oocyte enucleation without applying a fluorescent dye and (2) to study the effect of laser destruction of chromosomes on the structure and dynamics of the spindle. Approach: We applied polarized light microscopy for spindle visualization and performed stain-free mouse and human oocyte enucleation with a 1033 nm femtosecond laser. Also, we studied transformation of a spindle after metaphase plate elimination by a confocal microscopy. Results: We demonstrated a fundamental possibility of inactivating the metaphase plate in mouse and human oocytes by 1033 nm femtosecond laser radiation without applying a fluorescent dye. Irradiation of the spindle area, visualized by polarized light microscopy, resulted in partly or complete metaphase plate destruction but avoided the microtubules impairment. After the metaphase plate elimination, the spindle reorganized, however, it was not a complete depolymerization. Conclusions: This method of recipient cytoplast preparation is expected to be useful for animal cloning and assisted reproductive technologies. [ABSTRACT FROM AUTHOR]

Work from home (WFH) has been a part of the professional landscape for over two decades, yet it was the COVID-19 pandemic that has substantially increased its prevalence. The impact of WFH on careers is rather ambiguous, and a question remains open about how this effect is manifested in the current times considering the recent extensive and widespread use of WFH during the pandemic. To answer these questions, this article investigates whether managerial preferences for promotion, salary increase and training allowance depend on employee engagement in WFH. We take into account the employee's gender, parental status as well as the frequency of WFH. Furthermore, we examine whether managers' experience with WFH and its prevalence in the team moderate the effect of WFH on careers. An online survey experiment was run on a sample of over 1,000 managers from the United Kingdom. The experiment was conducted between July and December 2022. The findings indicate that employees who WFH are less likely to be considered for promotion, salary increase and training than on-site workers. The pay and promotion penalties for WFH are particularly true for men (both fathers and non-fathers) and childless women, but not mothers. We also find that employees operating in teams with a higher prevalence of WFH do not experience negative career effects when working from home. Additionally, the more WFH experience the manager has, the lesser the career penalty for engaging in this mode of working. Our study not only provides evidence on WFH and career outcomes in the post-pandemic context but also furthers previous understanding of how WFH impacts careers by showing its effect across different groups of employees, highlighting the importance of familiarisation and social acceptance of flexible working arrangements in their impact on career outcomes.

Background: The efficiency of different first-line treatments, such as first-line surgery and assisted reproductive technology (ART), in women with deep infiltrating endometriosis (DIE) is still unclear due to a lack of direct comparative trials. This systematic review and meta-analysis aim to elucidate and compare the efficacies of first-line treatments in patients with DIE, with an emphasis on fertility outcomes. Methods: An exhaustive search of PubMed Central, SCOPUS, EMBASE, MEDLINE, Cochrane trial registry, Google Scholar, and Clinicaltrials.gov databases was done to identify studies directly comparing first-line surgery and assisted reproductive technology (ART) for DIE, and reporting fertility-related outcomes. Pooled estimates for each of the binary outcomes were reported as odds ratios (ORs) with 95% confidence intervals (CIs). The results were pooled using a random- effects model with the Mantel-Haenszel technique. Results: Our results show that pregnancy rate per patient (OR, 1.47; 95% CI, 0.59 to 3.63), pregnancy rate per cycle (OR, 1.16; 95% CI, 0.45 to 2.99), and live births per patient (OR, 1.66; 95% CI, 0.56 to 4.91) were comparable in DIE patients, treated with surgery or ART as a first line of treatment. When both complete and incomplete surgical DIE excision procedures were taken into account, surgery was associated with a significant enhancement in the pregnancy rate per patient (OR, 1.63; 95% CI, 1.11 to 2.40). Conclusion: The available evidence suggests that both first-line surgery and ART can be effective DIE treatments with similar fertility outcomes. However, further analysis reveals that excluding studies involving endometriomas significantly alters the understanding of treatment efficacy between surgery and ART for DIE-associated infertility.

Infertility affects 1-in-6 couples, with repeated intensive cycles of assisted reproductive technology (ART) required by many to achieve a desired live birth. In ART, typically, clinicians and laboratory staff consider patient characteristics, previous treatment responses, and ongoing monitoring to determine treatment decisions. However, the reproducibility, weighting, and interpretation of these characteristics are contentious, and highly operator-dependent, resulting in considerable reliance on clinical experience. Artificial intelligence (AI) is ideally suited to handle, process, and analyze large, dynamic, temporal datasets with multiple intermediary outcomes that are generated during an ART cycle. Here, we review how AI has demonstrated potential for optimization and personalization of key steps in a reproducible manner, including: drug selection and dosing, cycle monitoring, induction of oocyte maturation, and selection of the most competent gametes and embryos, to improve the overall efficacy and safety of ART.

Obesity is associated with low vitamin D status, and the optimal supplement and dosage of cholecalciferol (vitamin D3) or calcidiol (25OHD) for individuals with obesity have been debated. We aimed to determine the effect of high-dose vitamin D3 supplementation on achieving adequate vitamin D levels among infertile men with normal weight v. obesity. Here, we present secondary end points from a single-centre, double-blinded, randomised clinical trial, comprising 307 infertile men randomised to active or placebo treatment for 150 days. Men in the active group initially received an oral bolus of 300 000 mg of vitamin D3, followed by daily supplementation with 1400 mg of vitamin D3 and 500 mg of calcium. Baseline BMI was listed as a predefined subgroup. At baseline, serum 25OHD was significantly higher in men with normal weight (BMI < 25 kg/m2) compared with men with overweight (BMI 25–30 kg/m2) and obesity (BMI > 30 kg/m2) (48 nmol/l v. 45 nmol/l and 39 nmol/l, respectively; P = 0·024). After the intervention, men with normal weight, overweight and obesity treated with vitamin D3 had a significantly higher serum 25OHD compared with corresponding placebo-treated men (BMI < 25 kg/m2: 92 nmol/l v. 53 nmol/l, BMI = 25–30 kg/m2: 87 nmol/l v. 49 nmol/l and BMI > 30 kg/m2: 85 nmol/l v. 48 nmol/l; P < 0·001 for all, respectively). In conclusion, we show that high-dose vitamin D3 supplementation to infertile men with obesity and low vitamin D status is sufficient to achieve adequate serum 25OHD levels. [ABSTRACT FROM AUTHOR]

Background: Growing focus on patient-centred care emphasizes humanistic skills and clinical narrative competence in nursing, particularly in assisted reproductive nursing. However, there is limited evidence to suggest the levels of nurse' clinical narrative competence and humanistic care ability. This study aimed to investigate the clinical narrative competence and humanistic care ability of nurse specialists in assisted reproductive technology (ART) in China. Methods: This cross-sectional study included nurses who obtained the ART specialist nurse certificate after nurse training in Zhejiang province assisted reproductive technology specialist nurse training base between 2017 and 2022. A demographic questionnaire, the Caring Ability Inventory (CAI) and Narrative Competence Scale (NCS) were used for data collection. Multivariate linear regression analysis was used to explore risk factors. Results: A total of 122 participants (120 females, with a mean age of 33.35 ± 5.00 years) were included (response rate = 82.43%). NCS score and CAI score was 143.39 ± 19.24 (range: 27–189) and 198.42 ± 19.51 (range: 37–259) among nurse specialists in assisted reproductive technology, respectively. Multivariate linear regression analysis indicated that professional title (β = 20.003, 95%CI: 3.271–36.735, P = 0.020), and the CAI (β = 0.342, 95%CI: 0.180–0.540, P < 0.001) was independently associated with NCS. Head Nurse/ Team Leader/ Clinical Faculty had significantly higher CAI score than nurse (P = 0.006). Conclusions: The clinical narrative competence and caring ability of nurse specialists in assisted reproductive technology was considered sufficient. Professional titles and work position were associated with clinical narrative competence. Enhancing clinical narrative competence can be considered as an effective strategy for promoting humanistic care ability. Trial registration: Not applicable. [ABSTRACT FROM AUTHOR]

The article tackles the acceptance of commodification and racial categorization in assisted reproductive technology (ART). Topics discussed include social justice issues in the fertility industry such as inequalities on the stage of procreation and racism, compensation structure for egg donors, current landscape of race and barriers to ART usage such as sociodemographic factors, racial selection in ART, and diversification of the egg donor market.

Despite the increased frequency of endometriosis, it remains one of the most enigmatic disorders regarding its effects on pregnancy. Endometriosis adversely affects both natural and assisted conception. Impaired folliculogenesis, which causes follicular dysfunction and low egg quality, as well as luteal phase problems, reduced fertilization, and abnormal embryogenesis, are some of the mechanisms advocated to explain reproductive dysfunction. There is a rising need for a comprehensive study of the potential negative consequences of this condition on pregnancy outcomes, including the postpartum period, as more women with a medical history of endometriosis become pregnant. Obstetrical complications (small for gestational age [SGA], cesarean section [CS], miscarriage, hemorrhage, low placental adhesion, and preterm delivery) are statistically elevated in women with endometriosis. Furthermore, ruptured ovarian endometrioma, appendicitis, intestinal perforation, and hemoperitoneum have been described in pregnancy. Obstetricians are largely unfamiliar with these complications, as they have not been thoroughly investigated. The development and pathogenesis of endometriosis is an important field of study and has not yet been fully elucidated. Finding these mechanisms is crucial for the development of new and more effective strategies to treat this condition. Endometriosis can have an impact on obstetric and neonatal outcomes of pregnancy, in addition to its potential effects on conception. To date, no additional monitoring is recommended for pregnancies with a history of endometriosis. However, more studies are urgently needed to assess the need for the tailored pregnancy monitoring of women with endometriosis. [ABSTRACT FROM AUTHOR]

Triptorelin is a first-line drug for assisted reproductive technology (ART), but the low bioavailability and frequent subcutaneous injection of triptorelin impair the quality of life of women preparing to become pregnant. We report silk fibroin (SF)-based microneedles (MNs) for transdermal delivery of triptorelin-loaded nanoparticles (NPs) to improve bioavailability and achieve safe and efficacious self-administration of triptorelin. Triptorelin was mixed into an aqueous solution of SF with shear force to prepare NPs to control the release and avoid the degradation of triptorelin by enzymes in the skin. Two-step pouring and centrifugation were employed to prepare nanoparticles-encapsulated polymeric microneedles (NPs-MNs). An increased β-sheet content in the conformation ensured that NPs-MNs had good mechanical properties to pierce the stratum corneum. Transdermal release of triptorelin from NPs-MNs was increased to ∼65%. The NPs-MNs exhibited a prolonged drug half-life and increased relative bioavailability after administration to rats. Surging levels of luteinizing hormone and estradiol in plasma and their subsequent prolonged downregulation indicate the potential therapeutic role of NPs-MNs in ART regimens. The triptorelin-loaded NPs-MNs developed in this study may reduce the physical and psychological burden of pregnant women using ART regimens. [ABSTRACT FROM AUTHOR]

Background Previous research has indicated that children conceived through medically assisted reproduction (MAR) generally have cognitive outcomes comparable to or better than naturally conceived children. However, previous studies have been limited in their ability to examine this relationship at a population level and consider variations across different types of MAR. Methods This study utilizes data from all live births in Denmark between 2006 and 2009 (n  = 259 608), including a subset of births resulting from MAR conceptions (n  = 13 566). The dependent variable is the standardized test scores obtained in the second and third grades of primary schools. A comparison is made between the test scores of children spontaneously conceived (SC) and those conceived through intrauterine insemination (IUI) and assisted reproductive technologies (ART). Ordinary least squares regressions are employed, with a baseline model adjusted only for birth year, as well as models that additionally account for conception-related confounders and sociodemographic family characteristics. Results In the baseline analysis, ART- and IUI-conceived children displayed better test scores compared with their SC peers. However, after adjusting for relevant factors, ART-conceived children performed worse than SC peers, while IUI-conceived children performed equally well as SC peers and better than ART-conceived children. Conclusions These results likely reflect differences in the selection process of potential parents into the type of MAR, as well as the consequences of variations in fecundability. Nevertheless, the differences observed across conception types were overshadowed by test score disparities in socioeconomic background. [ABSTRACT FROM AUTHOR]

Context: In vitro fertilisation (IVF) is now a common assisted reproductive technology (ART) procedure globally, with 8 million children alive today having been conceived utilising IVF. For many patients, IVF is a difficult experience with many discontinuing treatment because of emotional, relationship and financial stress, or intolerable physical side effects of hormone treatments. Design and Participants: A qualitative study, in which 31 professionals and 25 patients from the ART sector in Australia were interviewed. The interviews were analysed using codebook thematic analysis. Results: Our data indicates there are 'silences' within the therapeutic relationship of IVF, which may limit the capacity for patients to prepare emotionally, financially, or medically for the procedure, and may contribute to psychological distress and dissatisfaction with care. These 'silences' include what the patient 'is not told' by their clinician or 'does not hear' and what the patient feels they 'cannot say'. Discussion: Drawing upon the work of Jay Katz, Charis Thompson, and Miles Little on 'silences' and performance in clinical practice, we argue that although IVF is a complex and multifaceted procedure that is often conducted in a commercial setting, the clinical and therapeutic relationship between doctor and patient remains pivotal to the experiences of patients. The 'silences' within this relationship may impact negatively on decision‐making, and on the delivery and experience of care. Conclusions: Careful attention to the realities of IVF treatment in the clinic room (and awareness of the performances that hide them) should allow for more present and compassionate care. Such care may leave patients more satisfied with their experience and their choices, regardless of treatment outcomes. Patient or Public Contribution: This article draws on interviews with patients who had undergone or were currently undergoing IVF, as well as a range of representatives from the ART community (including reproductive medicine specialists, general practitioners, fertility nurses, counsellors, administrators in ART businesses and embryologists).

Background: Integrase inhibitor (INSTI) use has been associated with greater weight gain (WG) among people living with HIV (PLWH), but it is unclear how this effect compares in magnitude to traditional risk factors for WG. We assessed the population attributable fractions (PAFs) of modifiable lifestyle factors and INSTI regimens in PLWH who experienced a ≥5% WG over follow-up. Methods: In an observational cohort study from 2007 to 2019 at Modena HIV Metabolic Clinic, Italy, ART-experienced but INSTI-naive PLWH were grouped as INSTI-switchers vs non-INSTI. Groups were matched for sex, age, baseline BMI and follow-up duration. Significant WG was defined as an increase of ≥5% from 1st visit weight over follow-up. PAFs and 95% CIs were estimated to quantify the proportion of the outcome that could be avoided if the risk factors were not present. Results: 118 PLWH switched to INSTI and 163 remained on current ART. Of 281 PLWH (74.3% males), mean follow-up was 4.2 years, age 50.3 years, median time since HIV diagnosis 17.8 years, CD4 cell count 630 cells/µL at baseline. PAF for weight gain was the greatest for high BMI (45%, 95% CI: 27–59, p < 0.001), followed by high CD4/CD8 ratio (41%, 21–57, p < 0.001) and lower physical activity (32%, 95% CI 5–52, p = 0.03). PAF was not significant for daily caloric intake (−1%, −9-13, p = 0.45), smoking cessation during follow-up (5%, 0–12, p = 0.10), INSTI switch (11%, −19-36; p = 0.34). Conclusions: WG in PLWH on ART is mostly influenced by pre-existing weight and low physical activity, rather than switch to INSTI. [ABSTRACT FROM AUTHOR]

Introduction: Recurrent Pregnancy Loss and Recurrent Implantation Failure are major limiting factors in the establishment of pregnancy. Recurrent Pregnancy loss is defined as the failure of two or more clinically recognized pregnancies. A considerable proportion of infertile couples undergoing IVF treatment experiencing recurrent implantation failure (RIF) fail repeatedly to implant following at least three IVF cycles. MicroRNAs (miRNAs) can serve as reliable non-invasive diagnostic and prognostic biomarkers for pregnancy-related complications. Therefore, this study aimed to quantify miR-23a-3p expression level in the plasma of patients with idiopathic recurrent pregnancy loss (iRPL) and recurrent implantation failure compared to healthy subjects to evaluate its potential diagnostic value in iRPL and RIF patients. Material & Methods: This study is a cross-sectional descriptive study. A total of 120 plasma samples were obtained from 40 women with a history of at least two consecutive iRPL, 40 women with RIF, and 40 healthy women without a history of miscarriage to evaluate the expression level of the circulating miR-23a-3p by quantitative real-time polymerase chain reaction (qPCR) technique. All participants were recruited from Assisted Reproductive Technology (ART) and Stem Cell Research Center, Tabriz, Iran, September 2019-March 2020. Statistical analysis was performed using SPSS (version 22). Diagnostic efficiency of the circulating miRNAs was determined by Receiver Operatig Characteristic curve analysis using Graphpad Prism version 9.1.1. Findings: Our results showed that the miR-23a-3p expression level in plasma of iRPL patients was lower than those in healthy controls but without a statistically significant difference (P=0.113). We also found that miR-23a-3p plasma level in patients with RIF tended to be lower compared to healthy participants; however, it was not statistically significant (P=0.974). Discussion & Conclusion: The current study provides evidence indicating that downregulation of miR-23a-3p may be associated with iRPL and RIF. Therefore, further research is needed, such as using different geographic regions, large sample sizes, and other techniques (microarray). [ABSTRACT FROM AUTHOR]

STUDY QUESTION Is serum anti-Müllerian hormone (AMH) level predictive of cumulative live birth (CLB) rate after ART or in women trying to conceive naturally? SUMMARY ANSWER Serum AMH level is linked to CLB after IVF/ICSI but data are lacking after IUI or in women trying to conceive without ART. WHAT IS KNOWN ALREADY Serum AMH level is a marker of ovarian reserve and a good predictor of ovarian response after controlled ovarian stimulation. It is unclear whether AMH measurement can predict CLB in spontaneous or assisted conception. STUDY DESIGN, SIZE, DURATION A systematic review and meta-analysis was undertaken to assess whether serum AMH level may predict chances of CLB in infertile women undergoing IVF/ICSI or IUI and/or chances of live birth in women having conceived naturally. PARTICIPANTS/MATERIALS, SETTING, METHODS A systematic review and meta-analysis was performed using the following keywords: 'AMH', 'anti-mullerian hormone', 'live-birth', 'cumulative live birth'. Searches were conducted from January 2004 to April 2021 on PubMed and Embase. Two independent reviewers carried out study selection, quality, and risk of bias assessment as well as data extraction. Odds ratios were estimated using a random-effect model. Pre-specified sensitivity analyses and subgroup analyses were performed. The primary outcome was CLB. MAIN RESULTS AND THE ROLE OF CHANCE A total of 32 studies were included in the meta-analysis. Overall, 27 articles were included in the meta-analysis of the relation between AMH and CLB or AMH and LB after IVF/ICSI. A non-linear positive relation was found in both cases. A polynomial fraction was the best model to describe it but no discriminant AMH threshold was shown, especially no serum AMH level threshold below which live birth could not be achieved after IVF/ICSI. After IVF–ICSI, only four studies reported CLB rate according to AMH level. No statistically significant differences in mean serum AMH levels were shown between patients with and without CLB, but with a high heterogeneity. After exclusion of two studies with high risks of bias, there was no more heterogeneity [ I 2 = 0%] and the mean AMH level was statistically significantly higher in women with CLB. There were not enough articles/data to assess the ability of AMH to predict CLB rate or find an AMH threshold after IUI or in women without history of infertility trying to conceive without ART. LIMITATIONS, REASONS FOR CAUTION The systematic review and meta-analysis had some limitations owing to the limits and bias of the studies included. In the present meta-analysis, heterogeneity may have been caused by different baseline characteristics in study participants, different stimulating protocols for ART, different serum AMH level thresholds used and the use of various assays for serum AMH. This could explain, in part, the absence of a discriminating AMH threshold found in this analysis. WIDER IMPLICATIONS OF THE FINDINGS Serum AMH level is linked to CLB rate after IVF/ICSI but no discriminating threshold can be established, therefore low serum AMH level should not be used as the sole criterion for rejecting IVF treatment, especially in young patients. Data are lacking concerning its predictive value after IUI or in women trying to conceive without ART. Our findings may be helpful to counsel candidate couples to IVF-ICSI.

The technique currently used for this purpose is flow cytometry combined with a cell sorter which separates X-chromosome-bearing sperm (X-sperm) and Y-chromosome-bearing sperm (Y-sperm) based on the difference in their DNA content. Immunoseparation is presented as a cheaper and less stressful alternative for spermatozoa sexing by Sringarm et al. [[4]], who showed that the use of magnetic microbeads coupled with scFv antibodies against Y-sperm (PY-microbeads) produced 82.65% of X-chromosome sperm in the selected fraction with acceptable sperm quality. Differences between high- and low-fertility bulls were found mainly in parameters related to sperm acrosome integrity when using a new fluorescence method that allowed the clear and precise detection of the sperm plasma membrane and acrosome: the ISAS3Fun method. The assessment of semen quality is used to identify factors that influence sperm performance and diagnose male infertility. [Extracted from the article]

Because many involuntarily childless people have equal interests in benefitting from assisted reproductive technologies like in vitro fertilization as a mode of treatment, we have normative reasons to ensure inclusive access to such interventions for as many of these people as is reasonable and possible. However, the prevailing eligibility criterion for access to assisted reproductive technologies—'infertility'—is inadequate to serve the goal of inclusive access. This is because the prevailing frameworks of infertility, which include medical and social infertility, fail to precisely capture and unify the relevance of certain involuntarily childless experiences as warranting assisted reproductive technology (ART) treatment. I argue that the least we can do for those who have an interest in accessing ARTs is to conceptualize involuntarily childless experiences in dialogue with interactionist and ecological models of disability, to outline a unified and more inclusive eligibility criterion.

Advances in neonatal care have pushed the limit of viability to incrementally lower gestations over the last decades. However, surviving extremely premature neonates are prone to long-term neurodevelopmental handicaps. This makes ethics a crucial dimension of periviable birth management. At 22 weeks, survival ranges from 1 to 15%, and profound disabilities in survivors are common. Consequently, there is no beneficence-based obligation to offer any aggressive perinatal management. At 23 weeks, survival ranges from 8 to 54%, and survival without severe handicap ranges from 7 to 23%. If fetal indication for cesarean delivery appears, the procedure may be offered when neonatal resuscitation is planned. At a gestational age ≥24 weeks, up to 51% neonates are expected to survive the neonatal period. Survival without profound neurologic disability ranges from 12 to 38%. Beneficence-based obligation to intervene is reasonable at these gestations. Nevertheless, autonomy of parents should also be respected, and parental consent should be sought prior to any intervention. Optimal counselling of parents involves harmonized cooperation of obstetric and neonatal care providers. Every fetus/neonate and every pregnant woman are different and have the right to be considered individually when treatment decisions are being made. [ABSTRACT FROM AUTHOR]

Introduction: Various adaptive radiation therapy (ART) methods have emerged, with little consensus amongst the literature as to which is most appropriate. This study aimed to compare dose mapping (DM) versus Monte Carlo recalculation (MCR), using cone beam computed tomography (CBCT) images when utilised in automated ART dose accumulation workflows in the MIM Maestro software package. Methods: The treatment plans for 38 cancer patients (19 prostate and 19 head and neck cases) were used to perform DM or MCR retrospectively upon CBCTs acquired during treatment, which were then deformably registered to the planning CT (DR-pCT) to facilitate dose accumulation. Dose-volume and region-of-interest data were extracted for the planning target volumes and organs at risk. Intraclass correlation (ICC) values and Bland-Altman plots were utilised to compare DM versus MCR doses on the CBCT images as well as CBCT versus DR-pCT doses. Results: When comparing DM and MCR on CBCTs, the differences across dose level mean dose differences were mostly within a -5% level of agreement based on the Bland-Altman plots, with over 67% of ICC values over 0.9 and indicative of good correlation. When these distributions were deformed back to the planning CT, the agreement was reduced considerably, with larger differences (exceeding -5%) resulting from workflow-related issues. Conclusion: The results emphasise the need to consider and make adaptations to minimise the effect of workflows on algorithm performance. Manual user intervention, refined departmental protocols and further developments to the MIM Maestro software will enhance the use of this tool. [ABSTRACT FROM AUTHOR]

Infertility and related treatments can negatively affect a couple's wellbeing. The aim of this study was to evaluate couples starting assisted reproductive treatment, differences in alexithymia and quality of life levels between partners, and the association of these psychological dimensions within the couple's members. Data was collected in two fertility centres in Rome; 47 couples completed the Fertility Quality of Life (FertiQoL), the 20-item Toronto Alexithymia Scale (TAS-20), and a socio-demographic questionnaire. Data analysis showed a worsened quality of life in women compared with their partners, as well as higher externally oriented thinking in men compared with their spouses. Associations between alexithymia and quality of life levels between women and men emerged. According to the regression analysis, a better quality of life in women was predicted by a greater partner's capabilities in identifying and describing emotion as well as by a better partner's quality of life, whereas for men, a better quality of life was predicted by their spouse's higher levels of quality of life. This study highlights the protective role that couples can play in the perception of the negative impact that infertility can have on their partner's quality of life. Further investigations are needed for the development of specific therapeutic interventions for the promotion of the couples' wellbeing. [ABSTRACT FROM AUTHOR]

Brain abscesses are a possible complication of bacterial sepsis or central nervous system infection but are uncommon in the neonatal period. Gram-negative organisms often cause them, but Serratia marcescens is an unusual cause of sepsis and meningitis in this age group. This pathogen is opportunistic and frequently responsible for nosocomial infections. Despite the existing antibiotics and modern radiological tools, mortality and morbidity remain significant in this group of patients. We report an unusual unilocular brain abscess in a preterm neonate caused by Serratia marcescens. The infection had an intrauterine onset. The pregnancy was achieved through assisted human reproduction techniques. It was a high-risk pregnancy, with pregnancy-induced hypertension, imminent abortion, and required prolonged hospitalization of the pregnant woman with multiple vaginal examinations. The infant was treated with multiple antibiotic cures and percutaneous drainage of the brain abscess associated with local antibiotic treatment. Despite treatment, evolution was unfavorable, complicated by fungal sepsis (Candida parapsilosis) and multiple organ dysfunction syndrome. [ABSTRACT FROM AUTHOR]

This systematic review aimed to identify the benefits and possible harms of tocolytic therapy for preterm labour management in the context of pregnant women with extremely preterm birth, multiple gestations, or growth-restricted foetuses. A comprehensive search using MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, CINAHL, and the WHO Global Index Medicus databases was conducted from 10 to 15 July 2021. We included randomized controlled trials and non-randomized studies that assessed the effects of tocolysis compared with placebo or no treatment. We found 744 reports and, finally, nine studies (three randomized controlled trials and six cohort studies) pertaining to women with <28 weeks of gestation were included. No eligible studies were identified among women with a multiple pregnancy or a growth-restricted foetus. A meta-analysis of the trial data showed that there were no clear differences in perinatal death nor for a delay in birth. Non-randomized evidence showed that tocolysis delayed birth by 7 days, though there was no clear difference for preterm birth. In summary, it remains unclear whether tocolytic therapy for inhibiting preterm labour is beneficial for these subgroups of women and their newborns. Further well-designed randomized controlled trials and observational studies are needed to address the lack of evidence regarding tocolytic agents in these populations. [ABSTRACT FROM AUTHOR]

Purpose: In vitro maturation (IVM) continues its evolution as new ideas are introduced with the objective of making the IVM procedure easier and more effective. This study combines ideas believed likely to improve the IVM outcome or make the IVM oocyte identification process easier. Methods: A cohort of 45 women underwent an IVM cycle in which letrozole was used with the theoretical objective of improving the competence of small antral follicles, the oocyte aspiration technique was modified to minimize the time between oocyte aspiration and oocyte identification, and blastocysts were transferred during a subsequent cycle with controlled endometrial development. Results: Measures of oocyte competence used for these prospectively followed cycles were as follows: the maturation rate was 90.5%, the fertilization rate was 92.4%, the cleavage rate was 94.6%, the usable blastulation rate per zygote was 50.2%, and the implantation rate was 34.2%. Per transfer, the biochemical pregnancy rate was 63.2%, the clinical pregnancy rate was 55.3% and the ongoing/delivered pregnancy rate at the end of the first trimester was 47.4%. The miscarriage rate for clinical pregnancies in the first trimester was 14.3% and the ongoing twinning rate was 11.1%. [ABSTRACT FROM AUTHOR]
