BACKGROUND Family-planning policies have focused on contraceptive approaches to avoid unintended pregnancies, postpone, or terminate pregnancies and mitigate population growth. These policies have contributed to significantly slowing world population growth. Presently, half the countries worldwide exhibit a fertility rate below replacement level. Not including the effects of migration, many countries are predicted to have a population decline of >50% from 2017 to 2100, causing demographic changes with profound societal implications. Policies that optimize chances to have a child when desired increase fertility rates and are gaining interest as a family-building method. Increasingly, countries have implemented child-friendly policies (mainly financial incentives in addition to public funding of fertility treatment in a limited number of countries) to mitigate decreasing national populations. However, the extent of public spending on child benefits varies greatly from country to country. To our knowledge, this International Federation of Fertility Societies (IFFS) consensus document represents the first attempt to describe major disparities in access to fertility care in the context of the global trend of decreasing growth in the world population, based on a narrative review of the existing literature. OBJECTIVE AND RATIONALE The concept of family building , the process by which individuals or couples create or expand their families, has been largely ignored in family-planning paradigms. Family building encompasses various methods and options for individuals or couples who wish to have children. It can involve biological means, such as natural conception, as well as ART, surrogacy, adoption, and foster care. Family-building acknowledges the diverse ways in which individuals or couples can create their desired family and reflects the understanding that there is no one-size-fits-all approach to building a family. Developing education programs for young adults to increase family-building awareness and prevent infertility is urgently needed. Recommendations are provided and important knowledge gaps identified to provide professionals, the public, and policymakers with a comprehensive understanding of the role of child-friendly policies. SEARCH METHODS A narrative review of the existing literature was performed by invited global leaders who themselves significantly contributed to this research field. Each section of the review was prepared by two to three experts, each of whom searched the published literature (PubMed) for peer reviewed full papers and reviews. Sections were discussed monthly by all authors and quarterly by the review board. The final document was prepared following discussions among all team members during a hybrid invitational meeting where full consensus was reached. OUTCOMES Major advances in fertility care have dramatically improved family-building opportunities since the 1990s. Although up to 10% of all children are born as a result of fertility care in some wealthy countries, there is great variation in access to care. The high cost to patients of infertility treatment renders it unaffordable for most. Preliminary studies point to the increasing contribution of fertility care to the global population and the associated economic benefits for society. WIDER IMPLICATIONS Fertility care has rarely been discussed in the context of a rapid decrease in world population growth. Soon, most countries will have an average number of children per woman far below the replacement level. While this may have a beneficial impact on the environment, underpopulation is of great concern in many countries. Although governments have implemented child-friendly policies, distinct discrepancies in access to fertility care remain. [ABSTRACT FROM AUTHOR]

STUDY QUESTION Is the psychosocial wellbeing affected in women and men shortly after allocation to a freeze-all strategy with postponement of embryo transfer compared to a fresh transfer strategy? SUMMARY ANSWER In general, psychosocial wellbeing (i.e. emotional reactions to the treatment, quality-of-life, infertility-related stress, and marital benefit) was similar in women and men allocated to a freeze-all versus those allocated to a fresh-transfer strategy 6 days after disclosure of treatment strategy (i.e. 4 days after oocyte retrieval), although women in the freeze-all group reported a slightly higher degree of depressive symptoms and mood swings compared to women in the fresh transfer group. WHAT IS KNOWN ALREADY The use of a freeze-all strategy, i.e. freezing of the entire embryo cohort followed by elective frozen embryo transfer in subsequent cycles has increased steadily over the past decade in assisted reproductive technology (ART). This strategy essentially eliminates the risk of ovarian hyperstimulation syndrome and has proven beneficial regarding some reproductive outcomes in subgroups of women. However, patients experience a longer time interval between oocyte retrieval and embryo transfer, hence a longer time to pregnancy, possibly adding additional stress to the ART treatment. So far, little focus has been on the possible psychosocial strains caused by postponement of embryo transfer. STUDY DESIGN, SIZE, DURATION This is a self-reported questionnaire based sub-study of a multicentre randomized controlled trial (RCT) including 460 women and 396 male partners initiating their first, second, or third treatment cycle of invitro fertilisation or intracytoplasmic sperm injection (ICSI) from May 2016 to September 2018. This sub-study was included in the primary project protocol and project plan for the RCT, as psychosocial wellbeing was considered a secondary outcome. PARTICIPANTS/MATERIALS, SETTING, METHODS Women from eight public fertility clinics in Denmark and Sweden and one private clinic in Spain were randomized in a 1:1 ratio on the day of inclusion (menstrual cycle day 2 or 3) to either a freeze-all strategy with postponement of embryo transfer to a subsequent modified natural menstrual cycle or a fresh transfer strategy with embryo transfer in the hormone stimulated cycle. Treatment allocation was blinded until the day of the ovulation trigger. Women and their male partners were asked to complete a validated self-reported questionnaire 6 days after unblinding of treatment group allocation, corresponding to 4 days after oocyte retrieval, investigating their psychosocial wellbeing related to the treatment defined as emotional reactions to the treatment, quality-of-life, infertility-related stress, and marital benefit. The questionnaire included items from the Copenhagen Multi-Centre Psychosocial Infertility (COMPI) Fertility Problem Stress Scales and the COMPI Marital Benefit Measure. MAIN RESULTS AND THE ROLE OF CHANCE Baseline characteristics were comparable between the two groups for both women and men. In total, response rates were 90.7% for women and 90.2% for men. In the freeze-all group, 207 women and 179 men completed the questionnaire compared with 204 women and 178 men in the fresh transfer group. Men in the two treatment groups did not differ in any of the explored aspects of psychosocial wellbeing (i.e. emotional reactions to the treatment, quality-of-life, infertility-related stress, and marital benefit) 6 days after disclosure of treatment strategy. Women in the freeze-all group reported a slightly higher degree of depressive symptoms (P  =   0.045) and mood swings (P  =   0.001) (i.e. variables included in 'emotional reactions to treatment') compared to women in the fresh transfer group. When adjusted for multiple testing, depressive symptoms were no longer significantly different between the two groups. No additional differences in psychosocial wellbeing were found. Self-reported quality-of-life during treatment was also rated as similar between the two groups in both women and men, but was slightly lower than they would rate their quality-of-life when not in fertility treatment. LIMITATIONS, REASONS FOR CAUTION Although response rates were high, selection bias cannot be excluded. As this study was an RCT, we assume that psychosocial characteristics of the participants were equally distributed in the two groups, thus it is unlikely that the identified psychosocial differences between the freeze-all and fresh transfer group were present already at baseline. Furthermore, the questionnaire was completed as a one-time assessment 4 days after oocyte retrieval, thus not reflecting the whole treatment process, whereas an assessment after the full completed treatment cycle is needed to draw firm conclusions about the psychosocial consequences of the whole waiting period. However, a question posted that late would be highly biased on whether or not a pregnancy had been achieved. WIDER IMPLICATIONS OF THE FINDINGS The results indicate that individuals in the freeze-all group exhibited slightly higher levels of depressive symptoms and mood swings compared to those in the fresh transfer group. Nevertheless, it is important to note that any worries related to potential emotional strains stemming from delaying embryo transfer should not overshadow the adoption of a freeze-all approach in cases where it is clinically recommended. As long as patients are provided with comprehensive information about the treatment strategy before initiating the process, it is worth emphasising that other aspects of psychosocial wellbeing were comparable between the two groups.

STUDY QUESTION Are there any differences in physical and psychosocial well-being among women undergoing modified natural cycle frozen embryo transfer (mNC-FET) with or without vaginal progesterone as luteal phase support (LPS)? SUMMARY ANSWER Women undergoing mNC-FET with vaginal progesterone supplementation were more likely to experience physical discomfort but there was no difference in psychosocial well-being between the two groups. WHAT IS KNOWN ALREADY mNC-FET can be carried out with or without vaginal progesterone as LPS, which has several side-effects. It is commonly known that fertility treatment can cause stress and psychosocial strain, however, most studies on this subject are conducted in fresh cycle regimes, which differ from NC-FET and results may not be comparable. STUDY DESIGN, SIZE, DURATION This is a sub-study of an ongoing RCT investigating whether progesterone supplementation has a positive effect on live birth rate in mNC-FET. The RCT is conducted at eight fertility clinics in Denmark from 2019 and is planned to end primo 2024. The sub-study is based on two questionnaires on physical and psychosocial well-being added to the RCT in August 2019. On the time of data extraction 286 women had answered both questionnaires. PARTICIPANTS/MATERIALS, SETTING, METHODS Women who had answered both questionnaires were included in the sub-study. Participants were equally distributed, with 143 in each of the two groups. Participants in both groups received the same questionnaires at two time-points: on cycle day 2–5 (baseline) and after blastocyst transfer. Participants in the progesterone group had administered progesterone for 7 days upon answering the second questionnaire. All items in the questionnaires were validated. Items on psychosocial well-being originate from the Copenhagen Multi-Centre Psychosocial Infertility—Fertility Problem Stress Scale (COMPI-FPSS) and from the Mental Health Inventory-5. MAIN RESULTS AND THE ROLE OF CHANCE Women receiving progesterone experienced more vaginal itching and/or burning than women in the non-progesterone group (P  < 0.001). Women in the progesterone group also experienced more self-reported vaginal yeast infection, this was, however, not significant after adjustment for multiple testing (P/adjusted P  =   0.049/0.881). No differences regarding psychosocial well-being were found between the two groups. Within the progesterone group, a shift toward feeling less 'downhearted and blue' was found when comparing response distribution at baseline and after blastocyst transfer (P  < 0.001). LIMITATIONS, REASONS FOR CAUTION All items on physical symptoms were self-reported. The item on vaginal yeast infection was therefore not diagnosed by a doctor. Inclusion in the study required a few extra visits to the clinic, participants who felt more burdened by fertility treatment might have been more likely to decline participation. Women who experienced a lot of side-effects to progesterone prior to this FET cycle, might be less likely to participate. WIDER IMPLICATIONS OF THE FINDINGS Our results are in line with previous known side-effects to progesterone. Physical side-effects of progesterone should be considered before administration.

This study examines the formation of group cohesion and social support in exercise classes among former sedentary adults, participating in a Danish community-based intervention. Furthermore, the aim is to analyze the impact of this process on exercise activity among the participants. A multimethod approach was used, analyzing both survey data and 18 personal interviews collected among 87 participants who completed the intervention project. Analysis was performed according to the grounded theory method. The formation of group cohesion was conditioned by the social composition of the group, the teaching ability by the instructors, and the activity by itself. The cohesive group was characterized by an attitude of mutual support toward exercise activities. This mutual support facilitated development of self-efficacy beliefs among the participants improving their mastery expectation regarding exercise. Manipulating group dynamics may be a promising intervention tool in the promotion of leisure-time physical activity.

New legislation was introduced in Sweden in 2016, giving single women access to medically assisted reproduction (MAR). While Swedish single women's characteristics and motivations for choosing motherhood through MAR were assessed in our previous pilot survey, their experience of considering and making the decision to undergo MAR has not been assessed through a qualitative approach. Thus, the aim of this study was to explore Swedish single women´s experience of making the decision to choose motherhood through MAR. The study design was a qualitative method with a semi-structured interview guide used for individual face-to-face interviews. Sixteen single women accepted for MAR were interviewed individually during their waiting time to start treatment. Qualitative content analysis was used to analyse the data. The data analyses resulted in three main categories: (i) longing and belonging; (ii) social exclusion and support; and (iii) evaluation and encounter. The overarching theme reflects the decision to become a single mother by choice: motherhood through MAR – an emotional and ambivalent decision to make on your own. In conclusion, to reach motherhood, by giving birth to one's child and not deviating from the norm as childless, was considered important among these women when making the decision to become a single mother by choice.

This study explored young Danish men's perceptions and attitudes towards two fertility awareness (FA) interventions (a podcast episode and an informational poster) and their preferences for how fertility awareness and prevention efforts should be targeted and communicated to young men in the future. Focus groups were held with 13 young men who were between the ages of 25–35 and in a committed relationship over Zoom in January 2021. Data were analysed using qualitative content analysis. Young men preferred FA interventions to be factual as in the informational poster and to include personal stories that could serve as conversation starters as in the podcast. According to the young men, FA interventions should communicate using positive language and humour and not be negative or shaming. They preferred intervention formats like TV-programmes, podcasts, and social media. The participants also suggested fertility information should be included in sexual education in high school and vocational education. This research suggests that future FA campaigns should be developed in cooperation with the target group together with clinicians, and concurrent studies using different intervention formats should be performed. In all probability, a mix of different interventions is necessary to attain the desired effect to ensure long-lasting fertility awareness. [ABSTRACT FROM AUTHOR]

Being aware of factors that affect fertility can help people make informed decisions about their reproductive futures. To some, however, fertility information leads to worry and self-blame. In this paper, we explore how people from different generations discuss fertility and reproductive decision-making, along with their perceptions of fertility information. The study was conducted in southern Sweden with 26 focus-group discussions that included a total of 110 participants aged 17–90 years. The material was analysed thematically. Our results show that fertility knowledge and openness to talking about fertility problems have increased over generations. Participants who were assigned female at birth were more often concerned about their fertility than those who were not, and fertility concerns were transferred from mothers to daughters. While age-related fertility concerns had been uncommon in older generations, participants aged 25–40 often expressed these concerns. Young adults appreciated being knowledgeable about fertility but simultaneously expressed how fertility information could lead to distress. Our conclusion is that fertility information was best received by high-school students, and efforts to improve fertility education in schools are therefore recommended. [ABSTRACT FROM AUTHOR]

Study Question: How are educational level, labor market attachment and income associated with receiving a first ART treatment in either the public or private healthcare sector among women in Denmark?Summary Answer: Higher educational level and income as well as labor market attachment were associated with higher probability of initiating ART treatment at public and private fertility clinics among women in Denmark.What Is Known Already: Infertility is common in populations worldwide, and the approach to this issue differs between societies and healthcare systems. In the public Danish healthcare system, ART treatment is free of charge, and the direct cost for patients is therefore low. In the private healthcare sector in Denmark, ART treatment is self-financed. There is limited knowledge about the association between socioeconomic factors and seeking ART treatment, although previous studies have indicated that higher socioeconomic status is associated with seeking ART treatment.Study Design, Size, Duration: Women undergoing ART treatment during 1994-2016 registered in the Danish IVF register were individually linked with data from sociodemographic population registers using the Danish Personal Identification number. The study population consisted of 69 018 women treated with ART and 670 713 age-matched comparison women from the background population with no previous history of ART treatment.Participants/materials, Setting, Methods: The women included in the analyses were aged 18-45 years. The associations between attained educational level, labor market attachment and income and receiving a first ART treatment attempt were investigated for women either initiating treatment in the public sector or in the private sector, respectively. Information on age and origin was included as potential confounders, and odds ratios (ORs) were estimated in logistic regression models. In addition, analyses were stratified by age group to investigate potential differences across the age span.Main Results and the Role Of Chance: Adjusted results showed increased odds of receiving a first ART treatment in either the public or private sector among women with a higher educational level. Furthermore, women in employment were more likely to receive a first ART treatment in the public or private sector compared to women outside the workforce. The odds of receiving a first ART treatment increased with increasing income level. Surprisingly, income level had a greater impact on the odds of receiving a first ART treatment in the public sector than in the private sector. Women in the highest income group had 10 times higher odds of receiving a first ART treatment in the public sector (OR: 10.53 95% CI: 10.13, 10.95) compared to women in the lowest income group. Sub-analyses in different age groups showed significant associations between ART treatment and income level and labor market attachment in all age groups.Limitations, Reasons For Caution: Our study does not include non-ART treatments, as the national IVF register did not register these types of fertility treatments before 2007.Wider Implications Of the Findings: In Denmark, there is equal access to medically assisted reproduction treatment in the publicly funded healthcare system, and since there is no social inequality in the prevalence of infertility, social inequality in the use of ART treatment would not be expected as such. However, our results show that social inequality is found for a first ART treatment attempt across publicly and privately funded ART treatment across the socioeconomic indicators, educational level, labor market attachment and income.Study Funding/competing Interest(s): The funding for the establishment of the Danish National ART-Couple II Cohort (DANAC II Cohort) was obtained from the Rosa Ebba Hansen Foundation.

Study Question: Can animation videos on how to optimize the chances of pregnancy influence stress, anxiety, depression and sexual functioning of individuals trying to conceive (TTC)?Summary Answer: There were no differences between those educated to have intercourse every other day, on the fertile window and a control group (CG), and depression and sexual dysfunction significantly increased over time for all arms.What Is Known Already: Recent findings indicate that time to pregnancy can be significantly shortened by targeting the fertile period, but some reproductive care guidelines recommend instead the practice of intercourse every other day on the basis that it is less stressful to the couple. Evidence to support guidelines on how to preserve well-being and psychosocial adjustment and optimize pregnancy chances is lacking.Study Design, Size, Duration: We conducted a prospective, double-blinded, three-arm randomized controlled trial between July 2016 and November 2019. Participants were randomized to either not having any stimulus (CG) or visualizing a short animated video explaining how to improve chances of pregnancy by having intercourse every other day (EOD group), or by monitoring the fertile window (FWM group). Assessments were made before the intervention (T0), and 6 weeks (T1), 6 months (T2) and 12 months after (T3), with follow-ups censored in case of pregnancy.Participants/materials, Setting, Methods: Participants were childless individuals of reproductive age actively TTC and not diagnosed or unaware of a condition that could prevent spontaneous pregnancy. Individuals were excluded from recruitment if they had previous children or had a condition preventing spontaneous pregnancy. Our primary outcome was stress and secondary outcomes included anxiety, depression, sexual functioning and pregnancy. Primary analyses were performed according to intention-to-treat principle.Main Results and the Role Of Chance: Of the 450 randomized participants 127 were educated to use an every-other-day strategy, 135 to monitor the fertile window, and 134 received no intervention. Groups were similar regarding demographics and months TTC. Repeated measures analysis revealed that there were no significant interaction effects of psychological and sexual well-being between groups over time (P > 0.05). Significant time effects were revealed for stress (F(3,855) = 4.94, P < 0.01), depression (F(3,855) = 14.22, P < 0.01) and sexual functioning (time effects P values <0.001 for female sexual functioning dimensions and <0.002 for male dimensions), but not for anxiety (F(2,299) = 0.51, P > 0.05). Stress levels lowered after 6 months (P < 0.001) and returned to baseline levels at the 1-year follow-up. Depressive symptomatology significantly increased at 6 weeks (P = 0.023), and again 1 year after (P = 0.001). There were also significant decreases in all female sexual functioning dimensions (desire, satisfaction, arousal, pain, orgasm and lubrication). In men, there were significant variations in orgasm, intercourse satisfaction and erectile function, but not desire and sexual satisfaction. Revealed pregnancy rates were 16% for participants in the EOD group, 30% for the FWM group and 20% for the CG. Pregnancies were not significantly different between arms: EOD vs FWM (odds ratio (OR) 2.32; 95% CI 0.92-5.83); EOD vs CG (OR 0.74; 95% CI 0.30-1.87); and FWM vs CG (OR 1.71; 95% CI 0.70-4.18).Limitations, Reasons For Caution: Participants were recruited after transitioning to procreative sex. The study might be prone to bias as almost 30% of our sample fulfilled the chronological criterion for infertility, and other reproductive strategies could have been tried over time before recruitment.Wider Implications Of the Findings: Our data suggest that stress does not arise from feeling pressured on the fertile period and that advice on timing of intercourse might have to be personalized. The increasing levels of depression and sexual dysfunction over a year emphasize the crucial role of preconception care and fertility counseling in promoting psychological and sexual well-being.Study Funding/competing Interest(s): This work was supported by European Union Funds (FEDER/COMPETE-Operational Competitiveness Programme) and by national funds (FCT-Portuguese Foundation for Science and Technology) under the projects PTDC/MHC-PSC/4195/2012 and SFRH/BPD/85789/2012.Trial Registration Number: NCT02814006.Trial Registration Date: 27 June 2016.Date Of First Patient’s Enrollment: 19 July 2016.

Study Question: Is the chance of childbirth, and risk of infertility, pregnancy loss and need for assisted reproduction different for women with asthma compared to women without asthma?Summary Answer: Women with asthma had comparable chances of giving birth compared to the reference population, however, their risk of both infertility and pregnancy loss, as well their need for medically assisted reproduction, was higher.What Is Known Already: Reproductive dysfunction has been reported among women with asthma, including longer time to pregnancy, increased risk of pregnancy loss and a higher need of medically assisted reproduction, but their risk of clinical infertility is unknown.Study Design, Size, Duration: This longitudinal register-based cohort study included all women with a healthcare visit for delivery, infertility, pregnancy loss or induced abortion in the southernmost county in Sweden, over the last 20 years.Participants/materials, Setting, Methods: Using the Skåne Healthcare Register, we identified all women aged 15-45 between 1998 and 2019, who received a diagnosis of asthma before their first reproductive outcome (n = 6445). Chance of childbirth and risk of infertility, pregnancy loss and assisted reproduction were compared to a healthcare seeking population of women without any asthma (n = 200 248), using modified Poisson regressions.Main Results and the Role Of Chance: The chance of childbirth was not different between women with asthma versus those without, adjusted risk ratio (aRR) = 1.02, 95% CI: 1.01-1.03. The risk of seeking care for infertility was increased, aRR = 1.29, 95% CI: 1.21-1.39, and women with asthma more often needed assisted reproduction aRR = 1.34 95% CI: 1.18-1.52. The risk of suffering a pregnancy loss was higher, aRR = 1.21, 95% CI: 1.15-1.28, and induced abortions were more common, aRR = 1.15, 95% CI: 1.11-1.20, among women with asthma.Limitations, Reasons For Caution: The study was an observational study based on healthcare visits and lacked detailed anthropometric data, thus residual confounding cannot be excluded. Only women with a healthcare visit for a reproductive outcome were included, which cannot be translated into pregnancy intention. A misclassification, presumed to be non-differential, may arise from an incorrect or missing diagnosis of asthma or female infertility, biasing the results towards the null.Wider Implications Of the Findings: This study points towards reproductive dysfunction associated with asthma, specifically in regards to the ability to maintain a pregnancy and the risk of needing medically assisted reproduction following clinical infertility, but reassuringly the chance of subsequently giving birth was not lower for these women.Study Funding/competing Interest(s): This article is part of the ReproUnion collaborative study, co-financed by EU Interreg ÖKS, Capital Region of Denmark, Region Skåne and Ferring Pharmaceuticals.

Several studies worldwide have shown that reproductive-aged people often have inadequate fertility awareness (FA). Since attitudes and health behaviours are influenced by the partner, there is a need for studies exploring the role of these influences on the individuals' adoption of fertility protective behaviours (FPB). This study explores the role of FA and relationship quality on couples' intention to adopt FPB. One hundred and twelve childless couples answered an online questionnaire about reproductive life plan, FA and intentions to adopt FPB. The results showed that couples were moderately congruent on their reproductive life plan. The female partners who reported higher female relationship quality and higher female willingness to undergo fertility treatments were more willing to adopt FPB. The male partners who had heightened FA also reported higher intention to adopt FPB. The influences of male and female FA, relationship quality and congruence on reproductive life plan were neither associated with couples' congruence on the intention to adopt FPB. Although the cross-sectional design restricts our ability to draw causal conclusions, these findings emphasize that future interventions should be targeted at couples and designed according to their expectations and reproductive desires.

This study explored women's lived experience of making fertility decisions six years after attending the Fertility Assessment and Counselling (FAC) clinic in Copenhagen, Denmark, which is a personalised fertility awareness intervention. We conducted a qualitative interview study with 24 women who attended the FAC clinic 6 years earlier. Interviews were semi-structured and broadly examined the women's perceptions and experience of the intervention during follow-up. Data was analysed using a phenomenological framework and themes were identified related to women's experience of making fertility decisions after attending the FAC clinic. The overarching theme regarding the women's lived experience of making fertility decisions after attending the FAC clinic was: Fertility decisions were guided by the 'family clock'. There were four themes: (i) Deciding to 'get started' by attending the FAC clinic; (ii) Sense of making informed and empowered decisions; (iii) Influence of partner status on fertility decisions; and (iv) Decisions dictated by circumstance over preference and knowledge. At follow-up, the majority (21 women, 88%) had become parents. More than half of the women said that they had not achieved their desired family size. Consideration of women's 'family clock' is necessary in personalised fertility awareness interventions to enable women to achieve their family goals. [ABSTRACT FROM AUTHOR]

The freeze all strategy has become a promising alternative to fresh embryo transfer in fertility treatment almost eliminating late ovarian hyperstimulation syndrome (OHSS) in the segmented cycle. There is a lack of in-depth knowledge regarding patients' attitudes towards the freeze all strategy. The aim of this study was to explore the attitudes towards a freeze all strategy compared with fresh embryo transfer in assisted reproductive technology (ART) treatment among couples in a public health care setting. We conducted semi-structured qualitative interviews with ten couples already participants in a randomised controlled trial (RCT) and undergoing ART treatment. The couple's responses showed five themes: (i) Starting treatment provides needed relief; (ii) Treatment must be provided with humanity; (iii) Provision of information instigates positive attitudes towards treatment; (iv) Fresh treatment – 'The normal way'; and (v) Freeze all treatment – 'The new black'. When thorough information about treatment procedures and safety aspects regarding both the freeze all and fresh embryo transfer strategy is given prior to initiation of treatment, couples feel secure and content, regardless of which treatment strategy is finally applied. This qualitative study found that starting treatment could prompt longed-for relief, as professionals would now 'take over' and assist in meeting the couple's family building goals.

Fertility awareness (FA) among young people is low. Fertility awareness interventions have been found to contribute to increase FA in the short-term. The long-term effectiveness of FA interventions on childless and presumed fertile people, committed in a heterosexual relationship and wishing to have children in the near future is not known. In a double-blind parallel randomized controlled trial conducted between 2016 and 2018, 652 childless partnered women were randomized to either watch a 5-min video about fertility (IG: 'Intervention Group') or to not receive any intervention (CG: 'Control Group'). Participants filled out an online questionnaire at the start of the study (and in the IG group immediately before intervention). They then completed the questionnaire after 1 month, 6 months and 1 year. The questionnaire assessed FA and intentions to adopt fertility-protective behaviours. In the IG, FA levels were found to increase at 1 month post-intervention. However, significant interaction effects between group and time were only found for four out of the seven FA variables at the 6-month and 1-year follow-up. No effects were found for: (i) intentions to adopt fertility-protective behaviours; or (ii) desired timing of pregnancy. These results suggest that the fertility video intervention seems to partially increase FA in the long term. Future studies should investigate the effectiveness of different intervention formats with a focus on overcoming high attrition rates. [ABSTRACT FROM AUTHOR]

Most previous studies about fertility knowledge and attitudes among men have been based on quantitative methods using questionnaires with fixed-choice response options. The aims of this qualitative study were to explore childless young men's reflections on fertility and infertility through semi-structured interviews. Danish (n = 17) and Swedish (n = 12) young childless men aged between 20 and 30 years in their last year of education were interviewed. Data were analysed using qualitative content analysis. Few informants had considered their own fertility, and most were positive towards fertility treatment. The young men had inadequate knowledge about factors that can potentially impair male and female fertility. On average, the young men each mentioned three different factors they believed influence male and female fertility: (i) health behaviour; (ii) factors beyond personal control; and (iii) age. None mentioned sexual transmitted infections (STIs) but most appeared aware of the effect of increasing age on fertility. The results of this study highlight the need for educational strategies to improve young men's knowledge about fertility and the factors that influence it, particularly about the potential adverse effect of STIs on fertility.

Introduction: The number of children and young adults who survive cancer has steadily increased over the past decades. Consequently, life circumstances after cancer have gained increasing importance. The aim of this study was to explore family formation and socio-economic status among 35-year-old men having survived cancer in childhood or early adulthood compared to an age-matched comparison group. Methods: This study is a national, register-based cohort study among 35-year-old men. Men diagnosed with cancer in childhood and early adulthood were registered between 1978 and 2016. At the time of diagnosis, each patient was randomly matched with 150 men without cancer from the background population within the same birth year. Those still alive at the age of 35 years were included in the study population. Results: The study population consisted of 4,222 men diagnosed with cancer in childhood or early adulthood and 794,589 men in the age-matched comparison group. Men who have survived cancer during childhood or early adulthood have a reduced probability of having children, and lower probability of getting married or of cohabitation than those from an age-matched comparison group. Men who have survived CNS cancer also have a lower probability of having a higher education than high school and a higher probability of being outside the workforce than those from an age-matched comparison group. Discussion/Conclusion: Many men who have survived cancer during childhood or early adulthood are influenced by their cancer later in life, which was apparent in family formation, educational achievements, and labour market attachment. Continued focus on rehabilitation and needs for support among the male survivors of childhood and youth cancer is warranted. [ABSTRACT FROM AUTHOR]

In high-income countries, parental age at first birth has increased and this postponement increases the risk of involuntary childlessness or having fewer children than desired. This interview study was conducted in Denmark and Sweden among childless men (n = 29) in their last year of an education. The aim was to explore the role of individual and societal factors on fertility decision-making and men's reflections on barriers and enablers for earlier family formation. Data were analysed with thematic content analysis. Almost all participants wanted children in the future. Overall, there was a desire to follow the 'right chronology': get educated, having a stable relationship, employment and a good financial status before having children. While most men felt mature enough to have children, they were still not ready. Influences from within the inner social circle, societal expectations, the need for security and stability and being ready to give up freedom and individuality were factors that affected participants' preferred timing of parenthood. Most men did not have suggestions for how earlier family formation could be supported. Results suggest a gap between the ideal biological and ideal social age of family formation that may lead to unfulfilled parenthood aspirations. [ABSTRACT FROM AUTHOR]
