BACKGROUND: Infertility is prevalent and stigmatized in sub-Saharan Africa. Self-rated health, a subjective indicator that has been consistently related to objectively measured health, may be useful in evaluating the relationship between women's infertility and health. METHODS: Data were from surveys conducted from July 2014 to January 2015 with women aged 15 to 39 years (n = 915) as part of the initial assessment in a cohort study in Lilongwe district, Malawi...

STUDY QUESTION: Do assisted reproductive technologies alter DNA methylation and/or transcription of transposable elements and imprinted genes in cord blood and placenta? SUMMARY ANSWER: After ART, DNA methylation and/or transcription changes of some transposable elements and imprinted genes were found in placenta samples while transcription modifications for some transposable elements were also discovered in cord blood. WHAT IS KNOWN ALREADY: Recent studies have confirmed the increased risk of placenta-related adverse pregnancy outcomes and the excess of imprinted disorders with abnormal methylation patterns after ART, which raises the issue of a potential ART-induced epigenetic risk...

STUDY QUESTION: What is the dynamics of expression of P-element induced wimpy testis-like (PIWIL) proteins in the germline during human fetal development and spermatogenesis? SUMMARY ANSWER: PIWIL1, PIWIL2, PIWIL3 and PIWIL4 were expressed in a sex-specific fashion in human germ cells (GC) during development and adulthood. PIWILs showed a mutually exclusive pattern of subcellular localization. PIWILs were present in the intermitochondrial cement and a single large granule in meiotic GC and their expression was different from that observed in mice, highlighting species-differences...

REVIEW
Nikos F Vlahos, Theodoros D Theodoridis, George A Partsinevelos
Among uterine structural abnormalities, myomas and adenomyosis represent two distinct, though frequently coexistent entities, with a remarkable prevalence in women of reproductive age. Various mechanisms have been proposed to explain the impact of each of them on reproductive outcome. In respect to myomas, current evidence implies that submucosal ones have an adverse effect on conception and early pregnancy. A similar effect yet is not quite clear and has been suggested for intramural myomas. Still, it seems reasonable that intramural myomas greater than 4 cm in diameter may negatively impair reproductive outcome...

REVIEW
Jang-Kyung Park, Dong-Il Kim
Despite the development of assisted reproductive technology (ART), it is difficult to increase the implantation rate. In Korea, Traditional Korean Medicine, including herbal medicine, is an important component of infertility treatment. Korean medical doctors who are treating infertility often use herbal medicine to promote implantation. In this article, as one of the research works on modernization of Traditional Korean Medicine, we investigated the experimental studies to clarify the effects of herbal medicines that are traditionally used to promote pregnancy...

The pivotal role of androgen receptor (AR) in regulating male fertility has attracted much research attention in the past two decades. Previous studies have shown that total androgen receptor knockout would lead to incomplete spermatogenesis and a lowered serum testosterone levels in mice, resulting in azoospermia and infertility. However, the precise physiological role of ar in controlling fertility of male fish is still poorly understood. In this study, we have established an ar knockout zebrafish line by transcription activator-like effectors nucleases (TALENs)...

AIMS: The etiology of infertility is still unknown in almost half of all male infertility patients. In sperm, DNA condensation differs from somatic and female gamete cells, with the protamine (PRM) gene and its transcription factor, Y-box binding protein 2 (YBX2), playing key roles in making the structure more compact. Protamine polymorphisms have been studied in different populations, but various results have been acquired. MATERIALS AND METHODS: In our study, we examined, for the first time in a Turkish population, the association between protamine gene alleles (PRM1 c...

The safety profile of the herbicide glyphosate and its commercial formulations is controversial. Reviews have been published by individuals who are consultants and employees of companies commercializing glyphosate-based herbicides in support of glyphosate's reapproval by regulatory agencies. These authors conclude that glyphosate is safe at levels below regulatory permissible limits. In contrast, reviews conducted by academic scientists independent of industry report toxic effects below regulatory limits, as well as shortcomings of the current regulatory evaluation of risks associated with glyphosate exposures...

Kallmann syndrome is a rare genetic condition causing congenital hypogonadotropic hypogonadism. It presents with delayed puberty, anosmia, and infertility. Here, we set out to identify a causative DNA variant for Kallmann syndrome in two affected brothers of Hispanic ancestry. The male siblings presented with a clinical diagnosis of Kallmann syndrome (anosmia, delayed puberty, azoospermia, and undetectable luteinizing hormone and follicle stimulating hormone levels). Genetic variations were investigated by whole exome sequencing...

STUDY QUESTION: Does maternal age at a daughter's birth predict her subsequent probability of lifelong childlessness? SUMMARY ANSWER: In this study population, women born to older mothers were more likely to be childless. WHAT IS KNOWN ALREADY: Although maternal age at childbearing is increasing in many countries, there is limited evidence on whether being born to older parents may influence offspring fertility. STUDY DESIGN SIZE AND DURATION: This analysis included 43 135 women from the US-based Sister Study, a cohort study of 50 884 sisters of women with breast cancer recruited between 2003 and 2009...

In Kenya, sexually transmitted infections (STIs) such as Chlamydia trachomatis, Neisseria gonorrhoea, HIV, herpes simplex virus type 2 (HSV-2), syphilis and trichomoniasis tend to be prevalent, especially in women. Further, the research shows that women who test positive for STIs (other than HIV), have little knowledge of these infections. Of particular concern, is that there has been little attention on the part of government to educate the general public about STIs, yet these diseases can have devastating consequences on women's and men's health...

Introduction: It is well known that cervical incompetence and associated preterm birth confers greater morbidity and mortality on birth outcomes, with an additional increased risk of cervical incompetence in higher order gestations. While the pathophysiology of cervical incompetence has yet to be elucidated, research has identified risk factors and assessed outcomes of numerous interventions. Cervical cerclage has been shown, in certain situations involving singleton pregnancies, to improve outcomes...

Two leading European professional societies, the European Society of Human Genetics and the European Society for Human Reproduction and Embryology, have worked together since 2004 to evaluate the impact of fast research advances at the interface of assisted reproduction and genetics, including their application into clinical practice. In September 2016, the expert panel met for the third time. The topics discussed highlighted important issues covering the impacts of expanded carrier screening, direct-to-consumer genetic testing, voiding of the presumed anonymity of gamete donors by advanced genetic testing, advances in the research of genetic causes underlying male and female infertility, utilisation of massively parallel sequencing in preimplantation genetic testing and non-invasive prenatal screening, mitochondrial replacement in human oocytes, and additionally, issues related to cross-generational epigenetic inheritance following IVF and germline genome editing...
