This analysis was performed to determine whether the presence of soluble human leukocyte antigen-G (sHLA-G) in embryo culture medium is predictive of clinical outcomes in IVF treatment. The outcomes of implantation, clinical pregnancy, multiple pregnancy and miscarriage, between groups with and without sHLA-G in embryo culture media, were analysed. Fifteen studies with a total of 6170 cases were included. Ten of them were prospective studies while five were retrospective studies. Embryo culture media with sHLA-G were associated with significantly higher implantation rate and clinical pregnancy rate when compared with those without; the odd ratios (ORs) were 2...

STUDY QUESTION: Can pharma drug discovery approaches be utilized to transform investigation into novel therapeutics for male infertility? SUMMARY ANSWER: High-throughput screening (HTS) is a viable approach to much-needed drug discovery for male factor infertility. WHAT IS KNOWN ALREADY: There is both huge demand and a genuine clinical need for new treatment options for infertile men. However, the time, effort and resources required for drug discovery are currently exorbitant, due to the unique challenges of the cellular, physical and functional properties of human spermatozoa and a lack of appropriate assay platform...

STUDY QUESTION: Does thyroid autoimmunity (TAI) predict live birth rate in euthyroid women after one treatment cycle in IUI patients? SUMMARY ANSWER: TAI as such does not influence pregnancy outcome after IUI treatment. WHAT IS KNOWN ALREADY: The role of TAI on pregnancy outcome in the case of IVF/ICSI is largely debated in the literature. This is the first study to address this issue in the case of IUI. STUDY DESIGN, SIZE, DURATION: This was a retrospective cohort study...

Although the technique of intracytoplasmic sperm injection (ICSI) has been a revolution in the alleviation of male infertility, the use of testicular sperm for ICSI was a formerly unseen breakthrough in the treatment of the azoospermic man with primary testicular failure. At the clinical level, different procedures of testicular sperm retrieval (conventional TESE, micro-TESE, FNA/TESA, MESA, PESA) are being performed, the choice is mainly based on the cause of azoospermia (obstructive versus non-obstructive) and the surgeon's skills...

BACKGROUND AND OBJECTIVE: Luteal phase physiology is distorted by in vitro fertilization (IVF) cycles using gonadotropin-releasing hormone (GnRH) agonists and antagonists, Controlled ovarian hyperstimulation leads to luteal phase defect and for this reason, luteal phase support is now an integral part of IVF/ICSI-ET programs. The support is provided by hCG, progesterone or GnRH-a. This study compared the efficiency, safety and tolerance of two vaginal micronized progesterones, Utrogestan and Crinone 8%...

This case report describes a live birth after the fresh replacement of an embryo obtained from a spontaneously in vitro matured oocyte. The patient was subjected to controlled ovarian stimulation for IVF treatment, obtaining two oocytes. One was found to be immature at the time of denudation, at metaphase-I. This immature oocyte was kept in culture overnight in standard conditions along with the second oocyte - which was mature but failed to fertilize - spontaneously achieving metaphase-II, and was subjected to ICSI...

Poor responders represent one of the greatest challenges in assisted reproduction. The very diagnosis threatens the proposed benefit of in vitro fertilization (IVF): attaining a numeric advantage. Thus, it may seem somewhat logical that steps to maximize this numeric advantage may prove beneficial in this population. In this issue of BJOG, Haydardedeoglu et al. assess the benefit of follicular flushing in poor responders undergoing IVF and intracytoplasmic sperm injection (IVF/ICSI) as compared to direct aspiration in a randomized control trial (Haydardedeoglu et al...

OBJECTIVE: The use of gonadotropin-releasing hormone agonist for ovulation triggering has become an intriguing topic in the last few years. As long as adequate luteal phase support is provided, it may be a valuable alternative to standard hCG triggering, associated with a significant reduction in OHSS incidence. Several luteal phase support options have been proposed, but few studies have addressed the issue of the appropriate route for progesterone administration to women triggered with GnRHa...

In bovine, intracytoplasmic sperm injection (ICSI) remains inefficient partially due to low levels of sperm decondensation. The aim of this study was to determine whether the injection of normal size sperm pretreated with heparin (Hep) and l-glutathione (GSH), the use of sex-sorted sperm, the double round of sperm freezing/thawing (re frozen), or the combination of these approaches can improve sperm decondensation and embryo development after ICSI in cattle. Cleavage and blastocyst rates were evaluated on days 2 and 7 post ICSI...

OBJECTIVE: It has been suggested that a progesterone/estradiol ratio (P/E2) ≥ 1.0 on the day of human chorionic gonadotropin (hCG) administration indicates premature luteinization and might be associated with an adverse pregnancy; however, a lower limit of this ratio has not been determined. We aimed to identify a lower limit of P/E2 that correlates significantly with an increase in adverse pregnancies in patients undergoing a prolonged in vitro fertilization/intracytoplasmic sperm injection therapy...
