EDITORIAL
W Ombelet, J Goossens
The consequences of involuntary childlessness in developing countries create more wide-ranging societal problems compared to Western societies, particularly for women. Negative psychosocial and economical consequences for childless couples are often severe and underestimated by the local and international society. Infertility treatment is often limited to certain procedures and certain costumers. Most common arguments against supporting infertility care in resource-poor countries are the "overpopulation" and the "limited resources" argument, but they totally neglect the reproductive rights and systematic exclusion of millions of women from the right to reproduce...

In in vitro fertilization (IVF) cycles, some patients show a high rate of immature oocytes retrieved after controlled ovarian stimulation. In vitro oocyte maturation is an experimental technique, with poorer results than conventional IVF. For this reason, improving in vivo maturation could meliorate the reproductive outcome of these patients. We performed a retrospective, not interventional, study analyzing the difference in the number and percentage of mature oocytes retrieved in patients with more than 50% immature oocytes in a previous IVF cycle triggered with human chorionic gonadotropin (hCG) compared to the number and rate of mature oocytes retrieved in subsequent cycles, triggered with both gonadotropin-releasing hormone agonist (GnRH-a) and hCG...

Differences in cumulus cell gene expression after oocyte maturation in vitro (IVM) or in vivo have been described in previous studies. However, the possible impact of follicle stage on gene expression deregulation during human oocyte IVM remains unknown. Expression of selected genes of interest was compared in cumulus cell of three classes of human cumulus cell-oocyte complexes (COCs): a) COCs derived from human chorionic gonadotropin (hCG)-triggered IVM cycles, collected at the germinal vesicle (GV) stage from mid-sized follicles (4-12 mm) and matured in vitro (IVM-GV); b) COCs derived from hCG-triggered IVM cycles, collected from mid-sized follicles (4-12 mm) and matured in vivo (IVM-MII); c) COCs derived from controlled ovarian stimulation in vitro fertilization (IVF) cycles, collected from large/preovulatory follicles and matured in vivo (IVF-MII)...

Abnormal vaginal microbiota (AVM) or bacterial vaginosis (BV) might negatively impact reproductive outcomes of in vitro fertilization (IVF). However, before randomized controlled trials are initiated to investigate cause and effect, it is necessary to establish the optimal treatment for AVM. Metronidazole seems ineffective to treat the biofilm in AVM; thus, clindamycin could be suggested as a relevant antibiotic agent for future intervention based studies. In the present case report, we present the first longitudinal follow-up of the vaginal microbiota with molecular methods during and after oral clindamycin treatment...

BACKGROUND: The use of immature oocytes derived from stimulated cycles could be of great importance, particularly for urgent fertility preservation cases. The current study aimed to determine whether in vitro maturation (IVM) was more successful before or after vitrification of these oocytes. MATERIALS AND METHODS: This prospective study was performed in a private in vitro fertilization (IVF) center. We collected 318 germinal vesicle (GV) oocytes from 104 stimulated oocyte donation cycles...

BACKGROUND: The aim of this theoretical study is to explore the cost-effectiveness of aneuploidy screening in a UK setting for every woman aged under the age of 40 years when fresh and vitrified-warmed embryos are transferred one at a time in a first full cycle of assisted conception. METHODS: It is envisaged that a 24-chromosome genetic test for aneuploidy could be used to exclude embryos with an abnormal test result from transfer, or used only to rank embryos with the highest potential to be viable; the effect on cumulative outcome is assessed...

So-called mild controlled ovarian hyperstimulation (mCOH) has in recent years increased in popularity, claiming to be safer and more patient-friendly, while also improving in vitro fertilization (IVF) outcomes. We here challenge the International Society for Mild Approaches in Assisted Reproduction (ISMAAR) definition of mild stimulation, and especially address four fundamental issues, where our review found conventional COH (cCOH) advantageous over mCOH. They are: prevalence of severe ovarian hyperstimulation syndrome (OHSS), oocyte/embryo quality, pregnancy/live birth rates, and cost...

This review attempts to summarize the known literature on high responders to ovarian stimulation during assisted reproductive techniques (ART). Response to gonadotrophins is subject to significant interindividual and intercycle variation, thus carrying a risk of high response or poor response to ovarian stimulation regimens. The main risk for high responders is the development of ovarian hyperstimulation syndrome (OHSS) which is associated with significant morbidity. Hence, the definition of high responders in the literature has primarily focussed on risk factors for OHSS...

Short gamete co-incubation (SGCO) consists in decreasing the duration of contact between oocytes and sperm from the standard overnight insemination (SOI) toward 2 hours. However, the effectiveness of this technique to improve in vitro fertilization and embryo transfer (IVF-ET) outcomes remains controversial. Our study was designed to evaluate the efficiency of SGCO in a poor prognosis population with a history of fragmented embryos defined by the presence of at least 50% of the embryos with more than 25% of cytoplasmic fragments...

Evidence for the effect of granulocyte colony stimulating factor (G-CSF) on infertile women undergoing in vitro fertilization (IVF) remains inconsistent. This study aimed to evaluate the effectiveness of G-CSF on infertile women undergoing IVF. PubMed and EMBASE databases were searched before August 2016. Comparing the transvaginal perfusion of G-CSF and placebo or no treatment, the available studies were considered. The pooled risk ratio (RR) with 95% confidence intervals (CIs) was used in the analysis and six studies were included...

BACKGROUND: The expression of the 5,10-methylentetrahydrofolate reductase (MTHFR) gene in human oocytes and preimplantation embryos suggests that the MTHFR gene is involved in folliculogenesis and female reproduction. Considering the importance of the MTHFR gene on female reproduction, the aim of this study was to evalu- ate the influence of MTHFR C677T polymorphism on ovarian marker reserve, particularly serum anti-Müllerian hormone (AMH) levels, and ovarian response as well as clinical pregnancy rates after in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI)...

The phenotype of the human embryo conceived through in vitro fertilization (IVF), that is its morphology, developmental kinetics, physiology and metabolism, can be affected by numerous components of the laboratory and embryo culture system (which comprise the laboratory environment). The culture media formulation is important in determining embryo phenotype, but this exists within a culture system that includes oxygen, temperature, pH and whether an embryo is cultured individually or in a group, all of which can influence embryo development...

Recent observations suggest that the bovine uterus starts to react to the early embryo immediately after its arrival from the oviduct. The present study aimed to investigate the effect of the early developing embryo on the immune-related gene profile in bovine uterine epithelial cells (BUECs) in vitro, and to further examine the impact of conditioned media (CM), either from embryo-BUEC co-culture or embryo culture alone, on gene expression in peripheral blood mononuclear cells (PBMCs). First, BUECs were co-cultured with morulae (n = 10) for D5-D9 (D0 = IVF), and gene expression in BUECs was analyzed...

Anti-Müllerian hormone (AMH) is widely used in human medicine to non-invasively estimate the size of the ovarian follicle reserve and to predict the ovarian response to gonadotropin stimulation in the context of assisted reproductive technologies (e.g., IVF). These applications of AMH testing have recently expanded to non-human mammals, with production animals, such as cows, goats and sheep being the primary focus of AMH research. However, few investigations have involved exotic species, and in particular carnivores...
