Sperm DNA fragmentation refers to the accumulation of adducts as well as single- or double-strand DNA breaks and reflects the sperm DNA quality. Current data suggest that there are differences in sperm DNA quality among individuals with high or low fertility, and this observation has led to the idea that testing sperm DNA fragmentation could be a useful test of male fertility. However, sperm DNA fragmentation has become one of the most frequently debated topics in reproductive medicine, as there is no agreement about the optimal way to test for DNA fragmentation, the clinically significant level of sperm DNA fragmentation, as well as the best therapeutic options for infertile men. This article presents current evidence related to sperm DNA fragmentation and its role in managing male infertility., Competing Interests: The authors declare no conflicts of interest., (Thieme.

Endometrial injury to improve implantation for women undergoing assisted reproductive techniques has attracted a lot of attention recently and has rapidly become incorporated into clinical practice. The aim of this study is, thus, to assess the effectiveness and safety of endometrial injury performed in the cycle preceding assisted reproductive techniques in women with recurrent implantation failure. Electronic database searches, including MEDLINE, EMBASE, CENTRAL and grey literature, up to 30th May 2015 were conducted with no restrictions. Randomized controlled trials comparing endometrial injury versus placebo or no treatment in the cycle preceding assisted reproductive techniques in women with recurrent implantation failure were selected. The primary outcome was live birth rate. Secondary outcomes were clinical pregnancy, implantation, miscarriage and procedure-related complication rates. Of the 1115 publications identified, 4 met the inclusion criteria. Meta-analysis was not possible due to significant clinical heterogeneity among the included studies. Patients' characteristics differed, as did the intervention used with endometrial injury being performed at different phases of the preceding menstrual cycle. Moreover, the effect of endometrial injury on live birth and clinical pregnancy rates were inconsistent among the included studies. In summary, there is currently insufficient evidence to support the use of endometrial injury in women with recurrent implantation failure undergoing assisted reproductive techniques while the procedure-associated complication rate has not been assessed. Clinical implementation should, thus, be deferred until robust evidence becomes available., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)

The feasibility of posthumous reproduction when the surviving partner is female has brought to light many ethical, moral, social, and legal issues. This review aims to summarize these issues and to assist clinicians who may be faced with such requests. A question list, used for health technologies assessment, was utilized in a question-answer approach as the review methodology. Of the 1,208 publications identified through a comprehensive literature search in biomedical, psychological, and ethical databases, 31 articles included arguments related to one or more questions from the predefined question set. Key stakeholders identified include the deceased, the requesting party, the resultant child, the physician, and society. Key ethical issues relevant to posthumous reproduction include the four traditional pillars of medical ethics--autonomy, beneficence, nonmaleficence, justice--as well as the stakeholders' rights and sociocultural attitudes. The ethical framework formulated by these issues has been incorporated in a clinical ethics decision-making tool that could prove useful to clinicians and decision makers., (Copyright 2015 The Journal of Clinical Ethics.

Androgen- or anabolic steroid-induced hypogonadism (ASIH) is no longer confined to professional athletes; its prevalence amongst young men and teenagers using androgens and/or anabolic steroids (AASs) is rising fast, and those affected can experience significant symptoms. Clinicians are increasingly encountering demanding, well-informed men affected by ASIH, yet lacking authoritative information on the subject may struggle to project a credible message. In this article, we overview the methods and drugs that men use in an attempt to counteract ASIH (with a view to either preventing its onset, or reversing it once it has developed) and summarize the scientific evidence underpinning these. The main channel for obtaining these drugs is the Internet, where they can be readily sourced without a valid prescription. An Internet search using relevant terms revealed a huge number of websites providing advice on how to buy and use products to counteract ASIH. Drugs arising repeatedly in our search included human chorionic gonadotrophin (hCG), selective oestrogen receptor modulators (SERMs) and aromatase inhibitors (AIs). The quality and accuracy of the online information was variable, but review of medical literature also highlighted a lack of scientific data to guide clinical practice. It is important for clinicians to be aware of the AAS user's self-treatment strategies with regard to ASIH side-effect mitigation. By ensuring that they are well-informed, clinicians are more likely to retain the credibility and trust of AAS users, who will in turn likely be more open to engage with appropriate management., (© 2014 John Wiley & Sons Ltd.)

Objective: To evaluate the effectiveness of uterine-sparing interventions for women with symptomatic uterine fibroids who wish to preserve their uterus., Design: Systematic review and indirect comparison meta-analysis., Methods: MEDLINE, EMBASE, CENTRAL, conference proceedings, trial registers and reference lists were searched up to October 2013 for randomized controlled trials., Main Outcome Measures: Outcome measures were patient satisfaction, re-intervention and complications rates, reproductive outcomes, and hospitalization and recovery times., Results: Five trials, involving 436 women were included; two compared uterine artery embolization with myomectomy and three compared uterine artery embolization with laparoscopic uterine artery occlusion. Indirect treatment comparison showed that myomectomy and uterine artery embolization resulted in higher rates of patient satisfaction (odds ratio 2.56, 95% credible interval 0.56-11.75 and 2.7, 95% credible interval 1.1-7.14, respectively) and lower rates of clinical failure (odds ratio 0.29, 95% credible interval 0.06-1.46 and 0.37, 95% credible interval 0.13-0.93, respectively) than laparoscopic uterine artery occlusion. Myomectomy resulted in lower re-intervention rate than uterine artery embolization (odds ratio 0.08, 95% credible interval 0.02-0.27) and laparoscopic uterine artery occlusion (odds ratio 0.08, 95% credible interval 0.01-0.37) even though the latter techniques had an advantage over myomectomy because of shorter hospitalization and quicker recovery. There was no evidence of difference between the three techniques in ovarian failure and complications rates. The evidence for reproductive outcomes is poor., Conclusion: Our study's results suggest that laparoscopic uterine artery occlusion is less effective than uterine artery embolization and myomectomy in treatment of symptomatic fibroids. The choice between uterine artery embolization and myomectomy should be based on individuals' expectations and fully informed discussion., (© 2014 Nordic Federation of Societies of Obstetrics and Gynecology.)

Preterm birth continues to be one of the most important issues in current obstetric medicine, being the single largest cause of perinatal morbidity and mortality. The signals that initiate preterm and term labour remain a mystery. Intrauterine inflammation with the secretion of cytokines is one of the accepted explanations for the mechanism of initiation of preterm labour. This review discusses the current understanding of the molecular mechanisms for the initiation of preterm labour, focusing chiefly on the role of intra-amniotic fluid mediators, whether endogenous or infection-induced, in the regulation of inflammatory response pathways associated with spontaneous preterm labour. Prostaglandins (PGs) are considered to be one of the key mediators of preterm labour, with the concentration of biologically active PGs in the amniotic fluid, particularly PGE(2) and PGF(2α), being significantly higher in women with preterm labour. Cytokines, such as interleukins and tumour necrosis factor alpha, additionally play a dominant role in preterm labour, particularly in association with infection. Elevated amniotic fluid concentrations of extracellular matrix mediators, including metalloproteases, are also implicated in the process of foetal membrane rupture in preterm labour. Allelic variations in the main amniotic fluid mediators may be the key to understanding the disparity in the rates of preterm birth between different ethnic populations. We also discuss the role of other potential mediators such as cell-adhesion molecules, nitric oxide and novel biomarkers found in the amniotic fluid.

Primary ovarian carcinoid tumours of the ovary are rare and represent less than 0.1% of ovarian malignancy. The evidence to guide treatment and prognosis of these tumours is limited. We report a case of primary ovarian mucinous carcinoid tumour, of the atypical category, in a 34-year-old nulliparous woman. Only three such cases have previously been reported. At four years from presentation, she has no signs of metastatic disease, despite delayed primary surgery and then initial conservative management. At present surgical excision with close follow-up appears to be the management of choice. This case adds to the body of evidence and demonstrates a possible good prognosis with non-aggressive behaviour in the atypical mucinous carcinoid group.
