STUDY QUESTION: Compared to families with IVF singletons, what are parental depressive, parent-adolescent interaction and adolescent adjustment outcomes in families with 11-17-year-old IVF twins? SUMMARY ANSWER: No differences were detected for any measured outcome between families with 11-17-year-old IVF twins and those with IVF singletons, despite high statistical power. WHAT IS KNOWN ALREADY: When IVF twins are younger than 5-years-old, parents tend to have more mental health difficulties and poorer parent-child interactions relative to IVF singletons...

STUDY QUESTION: After an initial midtrimester loss, is the interval to the next conception associated with the risk of a recurrent loss? SUMMARY ANSWER: Among women who had a pregnancy loss at 14-19 weeks gestation, conception at least 3 months after this initial loss was associated with a reduced risk of a recurrent loss. WHAT IS KNOWN ALREADY: A short interpregnancy interval (IPI) has been thought to increase risk but recent studies of pregnancy after a loss have found no effect; however, these studies have been based almost entirely on an initial first trimester (<14 weeks) loss...

Embryonic mosaicism, defined as the presence of karyotypically distinct cell lines within an embryo, has been frequently reported with a high incidence in preimplantation embryos derived from IVF and is thought to be one of the major biological limitations for the routine application of PGD for aneuploidies (PGD-A). The incidence of mosaicism in preimplantation embryos is in fact reported to be between 4 and 90%. However, these data are in sharp contrast with what is known from clinical pregnancies, where true foetal mosaicism is observed in less than 0...

STUDY QUESTION: Does ICSI improve outcomes in ART cycles without male factor, specifically in couples with a history of tubal ligation as their infertility diagnosis? SUMMARY ANSWER: The use of ICSI showed no significant improvement in fertilization rate and resulted in lower pregnancy and live birth (LB) rates for women with the diagnosis of tubal ligation and no male factor. WHAT IS KNOWN ALREADY: Prior studies have suggested that ICSI use does not improve fertilization, pregnancy or LB rates in couples with non-male factor infertility...

STUDY QUESTION: Are uterine fibroids associated with increased cardiovascular risk? SUMMARY ANSWER: This study reports an association between increased serum lipids and metabolic syndrome with an increased risk of uterine fibroids. WHAT IS KNOWN ALREADY: Recent studies suggest similarities in biological disease mechanisms and risk factors for fibroids and atherosclerosis: obesity, hypertension and abnormal serum lipids. These findings are awaiting confirmation that a population-based follow-up study could offer with extensive health examination data collection linked with a national hospital discharge register...

STUDY QUESTION: Is sexual dysfunction associated with severity of semen quality impairment in men with couple infertility? SUMMARY ANSWER: In males of infertile couples the prevalence of erectile dysfunction (ED) increases as a function of semen quality impairment severity. WHAT IS KNOWN ALREADY: Infertile men are at a higher risk for sexual dysfunction, psychopathological and general health disorders. However, it has never been systematically investigated if these problems are associated with severity of semen quality impairment...

STUDY QUESTION: What is the semen quality of young adult men who were conceived 18-22 years ago by ICSI for male infertility? SUMMARY ANSWER: In this cohort of 54 young adult ICSI men, median sperm concentration, total sperm count and total motile sperm count were significantly lower than in spontaneously conceived peers. WHAT IS KNOWN ALREADY: The oldest ICSI offspring cohort worldwide has recently reached adulthood. Hence, their reproductive health can now be investigated...

STUDY QUESTION: How do the three new anti-Müllerian hormone (AMH) assay methods, manufactured by Beckman Coulter, Roche and Ansh Labs compare with each other and with the Gen II assay? SUMMARY ANSWER: The three new AMH assays are well correlated among themselves and with the Gen II assay, although differences in calibration do exist. WHAT IS KNOWN ALREADY: The Gen II assay has been the mainstay method for AMH measurement in the past few years...

Steroidogenic acute regulatory protein (StAR) mutations are the most frequent aetiologies of congenital lipoid adrenal hyperplasia (CLAH). Phenotypes may vary, and puberty may be absent in affected individuals. To date, only two pregnancies have been described in 46,XX CLAH patients with StAR mutations; these patients exhibited ovarian steroidogenesis along with spontaneous puberty and menarche and normal menses. The patient described here presented with CLAH caused by the homozygous (unreported, 1 bp) deletion c...

This article responds to a debate article published in Human Reproduction earlier this year. In that article, the authors suggested that parents should be encouraged to disclose the use of donor gametes to their children given rapid and widespread advances in genetic testing and sequencing. However, there is an urgent need to engage with the assertion that in this context, telling children about their donor conception both safeguards and promotes their interests, particularly if such disclosure is motivated by parents' anxieties about accidental discovery...

STUDY QUESTION: Are Inhibin B and testosterone levels reduced in boys with newly diagnosed cancer prior to therapy? SUMMARY ANSWER: Pretreatment serum levels of Inhibin B and testosterone are significantly reduced in boys with newly diagnosed cancer, compared to reference values. WHAT IS ALREADY KNOWN: Disease-related gonadal impairment has been demonstrated in girls and young women diagnosed with cancer, prior to therapy. STUDY DESIGN, SIZE, DURATION: We conducted a descriptive study in boys newly diagnosed with cancer between January 2006 and February 2014...

STUDY QUESTION: Does the intrauterine administration of hCG immediately after oocyte retrieval in antagonist cycles with ICSI and fresh embryo transfer (ET) influence the implantation rate or chemical and clinical pregnancy rates? SUMMARY ANSWER: The intrauterine administration of hCG after oocyte retrieval increases the implantation rate and chemical and clinical pregnancy rates. WHAT IS KNOWN ALREADY: Over half of IVF/ICSI cycles fail due to implantation failure...

STUDY QUESTION: Is it possible to extend the use of the 3-year one-rod etonogestrel (ENG)-releasing subdermal contraceptive implant to 5 years? SUMMARY ANSWER: The extended use of the one-rod ENG-releasing subdermal contraceptive implant showed 100% efficacy in years 4 and 5. WHAT IS KNOWN ALREADY: The initial regulated trials on the ENG-releasing subdermal contraceptive implant conducted in the 1990 s were designed to measure cumulative 3-year efficacy...

STUDY QUESTION: Does chronic stress in mice accelerate the development of endometriosis, and, if so, through what mechanism? SUMMARY ANSWER: Exposure to chronic stress accelerates the development of endometriosis and exacerbates the endometriosis-associated generalized hyperalgesia, most likely through activation of the adrenoceptor β2 (ADRB2) and cAMP responsive element-binding protein (CREB). WHAT IS KNOWN ALREADY: Women with endometriosis tend to have higher levels of psychological stress, which is known to impact negatively on health in general and to promote tumor growth and metastasis in particular...

STUDY QUESTION: Are women with endometriosis who conceive with IVF at increased risk of preterm birth? SUMMARY ANSWER: Women with endometriosis who conceive with IVF do not face an increased risk of preterm birth. WHAT IS KNOWN ALREADY: The eutopic endometrium of women with endometriosis has been repeatedly shown to present molecular and cellular alterations. On this basis, it has been hypothesized that pregnancy outcome may be altered in affected women...

STUDY QUESTION: Does autologous transplantation of menstrual blood-derived stromal cells (menSCs) regenerate endometrium to support pregnancy in patients with severe Asherman's syndrome (AS)? SUMMARY ANSWER: Autologous menSCs transplantation significantly increases endometrial thickness (ET) for women with severe AS. WHAT IS KNOWN ALREADY: AS is a major cause of secondary infertility in women. Cell transplantation has been tried in a few clinical cases with encouraging results...
