The impact of chemotherapy on fertility appears to be of essential importance for the youngest cancer survivors. The aim of this study was to assess plasma anti-Mullërian hormone (AMH) evolution, using an automated sensitive AMH immunoassay in women younger than 35 years old before and after treatment with adjuvant chemotherapy for early breast cancer. We selected 54 women aged less than 35 years old, at the time of breast cancer diagnosis, who received chemotherapy between 2008 and 2014, and with plasma samples collected from the diagnosis, to 1 year, 3 years and 5 years post-diagnosis...

This study aimed to determine whether karyomapping can be applied to couples requiring preimplantation genetic diagnosis (PGD) for single gene disorder (SGD) and/or chromosomal rearrangement. 75/82 (91.5%) and 6/82 (7.3%) couples were referred for autosomal SGD and X-linked disease, respectively. One couple (1.2%) was referred for SGD and chromosomal rearrangement. Of 608 embryos, 146 (24%, 95% CI 21-28) day-3 and 462 (76%, 95% CI 72-79) blastocyst biopsies were performed. A total of 81 embryo transfers were performed; 16/81 (20%) were following day-3 embryo biopsy, 65/81 (80%) were following blastocyst biopsy and cryopreserved embryo transfer...

Mutations in the tubulin beta 8 class VIII (TUBB8) gene have been proven to cause oocyte maturation arrest. The aim of this study was to describe newly discovered mutations in TUBB8 and to investigate the prevalence of TUBB8 mutations in our cohort. Nine women with oocyte maturation arrest and 100 fertile female controls were recruited. Sanger sequencing of the coding regions of TUBB8 revealed a heterozygous variant c.535G > A (p.V179M) in two unrelated affected individuals and a heterozygous variant c.5G > T (p...

Several studies have demonstrated that human embryonic stem cells (hESC) can be differentiated into trophoblast-like cells if exposed to bone morphogenic protein 4 (BMP4) and/or inhibitors of fibroblast growth factor 2 (FGF2) and the transforming growth factor beta (TGF-β)/activin/nodal signalling pathways. The goal of this study was to investigate how the inhibitors of these pathways improve the efficiency of hESC differentiation when compared with basic BMP4 treatment. RNA sequencing was used to analyse the effects of all possible inhibitor combinations on the differentiation of hESC into trophoblast-like cells over 12 days...

The current study investigates the utility of random-start ovarian stimulation in women desiring elective oocyte cryopreservation. Women in the study cohort underwent random-start ovarian stimulation, and were subdivided based on the phase of the menstrual cycle that ovarian stimulation began, i.e. early follicular, late follicular or luteal phase. Women undergoing conventional cycle day (CD) 2/3 ovarian stimulation start were controls. A total of 1302 women were included - 859 (66.0%) conventional CD 2/3, 342 (26...

A strong correlation between blastocyst morphology and implantation has been shown by many studies. The consequences and effects of assisted reproductive techniques on children's short and long-term health have always been a source of discussion. The obstetric and perinatal outcome of singletons according to blastocyst morphology has rarely been evaluated. The aim of this observational study is to determine whether a relationship exists between blastocyst morphology and obstetric and perinatal outcomes. A total of 799 singleton clinical pregnancies were analysed after transfer of a single fresh blastocyst on day 5 between 2006 and 2013...

There have been 60 births after transplantation of cryopreserved ovarian tissue: 58 using the slow freezing method, and two using the vitrification method. DMSO and EG are widely used as cryoprotectants. However DMSO is a known epimutagen, and EG has been reported to be toxic in high concentrations. In this study, we measured residual DMSO and EG in ovarian tissue after vitrification and slow freezing. Cryoprotectants remained at a high concentration in the vitrified/warmed ovarian tissue just before transplantation (DMSO: 9...

Belgian legislation limiting the number of embryos for transfer has been shown to result in a 50% reduction of the multiple live birth rate (MLBR) per cycle without having a negative impact on the cumulative delivery rate per patient within six cycles or 36 months. The objective of the current study was to evaluate the cost saving associated with a 50% reduction in MLBR. A retrospective cost analysis was performed of 213 couples, who became pregnant and had a live birth after one or more assisted reproductive technology treatment cycles, and their 254 children...

The relationship between serum anti-Müllerian hormone (AMH) levels, body mass index (BMI) and related metabolic factors were investigated in women with polycystic ovary syndrome (PCOS). A total of 691 women aged between 18 and 35 years, referred to the Department of Gynaecological Endocrinology at the University Hospital of Lille between 2009 and 2014 were included: 137 controls and 554 women with PCOS. Mean serum AMH levels were slightly but significantly lower in women with PCOS who were overweight or obese (BMI ≥25) compared with women of normal weight (BMI <25) (P < 0...

The current systematic review and meta-analysis evaluate the perinatal outcomes in twin pregnancies following multifetal pregnancy reduction (MPR) compared with non-reduced triplet pregnancies. All studies comparing perinatal outcome of twin pregnancies following MPR to non-reduced triplet pregnancies were considered. MEDLINE, non-indexed MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and Web of Science were searched for relevant published articles up to August 2016. The search yielded 653 publications of which 92 were assessed for eligibility...

Despite higher costs for robotic assisted laparoscopy (RAL) than standard laparoscopy (SL), RAL treatment of endometriosis is performed without established indications. PubMed/MEDLINE was searched for 'robotic surgery' and 'endometriosis' or 'gynaecological benign disease' from January 2000 to December 2016. Full-length studies in English reporting original data were considered. Among 178 articles retrieved, 17 were eligible: 11 non-comparative (RAL only) and six comparative (RAL versus SL). Non-comparative studies included 445 patients...

In this review, the definition, incidence and possible causes of empty follicle syndrome (EFS), including molecular mechanisms that may underlie the syndrome, are discussed, along with prevention and treatment options. EFS is the complete failure to retrieve oocytes after ovarian stimulation, despite apparently normal follicle development and adequate follicular steroidogenesis. Two variants of EFS have been described: the 'genuine' form (gEFS), which occurs in the presence of adequate circulating HCG levels at the time of oocyte aspiration, and the 'false' form (f-EFS), which is associated with circulating HCG below a critical threshold...

The Centre for Disease Control and Prevention (CDC) publicly reports assisted reproductive technology live-birth rates (LBR) for each US fertility clinic under legal mandate. The 2014 CDC report excluded 35,406 of 184,527 (19.2%) autologous assisted reproductive technology cycles that involved embryo or oocyte banking from LBR calculations. This study calculated 2014 total clinic LBR for all patients utilizing autologous oocytes two ways: including all initiated assisted reproductive technology cycles or excluding banking cycles, as done by the CDC...

With the development of IVF procedures, the role of reproductive surgery in the management of infertile couples has been questioned. Pregnancy rates (PR) after IVF procedures are well known, but recent data on spontaneous PR after reproductive surgery are scarce. This study aimed to prospectively evaluate how often fertility is restored by reproductive surgery and to identify which independent factors influence spontaneous pregnancy after reproductive surgery. Eight hundred eighty-eight infertile women who underwent surgery for infertility were prospectively included...

During short-term storage, before cryopreservation, testicular tissue quality can be affected by storage medium, duration, temperature and tissue size. We previously established the best storage medium and time for short-term maintenance of tissue. In this study, three different storage temperatures (4°C, room temperature, 37°C) and four tissue sizes (~6 mm(3); ~ 15 mm(3); ~ 50 mm(3) or ~80 mm(3)) were assessed over the course of a fixed period of 3 days. Storing human testicular tissue at 37°C caused a significant increase in the number of apoptotic cells per tubule (P = 0...

Recently, growing interest in vitamin D has emerged from findings that demonstrate a low vitamin D status in populations. Similarly, much interest has been shown in the role that anti-Müllerian hormone (AMH) plays in reproductive physiology. Considerable confusion as to whether vitamin D status is related to ovarian function can be found in the literature. Our retrospective study was performed from June 2014 to April 2015. Oocyte donors were recruited and stimulated under the antagonist protocol with gonadotrophin-releasing hormone (GnRH) agonist to trigger ovulation...
