OBJECTIVE: It was previously shown that higher concentrations of myo-inositol in human follicular fluid improve oocyte and embryo quality, whereas D-chiro-inositol seems to worsen oocyte quality and ovarian response in polycystic ovary syndrome patients. Our study was the first one aiming to test whether different myo-inositol and D-chiro-inositol concentration in follicular fluids correlate with blastocyst quality in healthy young women. PATIENTS AND METHODS: Eight egg donors and eleven couples undergoing in vitro fertilization, were involved in a prospective observational study...

OBJECTIVE: There are increasing concerns regarding the adverse effects associated with control ovarian hyperstimulation (COH) in both endometrial and uterine environments. With the "segmentation treatment policy" of assisted reproductive techniques (ART), endometrial problems may be obviated through embryo cryopreservation. However, it remains unclear if the "freeze-all policy" offers a better outcome when compared with fresh embryo transfer (ET). To clarify this, we compared the cumulative live birth rates (CLBRs) between these two patient populations...

Aneuploidy is of great relevance to embryo selection, as it represents one of the important causes of implantation failure. Furthermore, immature oocytes, retrieved during gonadotrophin-stimulated IVF cycles, are generally discarded in clinics; whereas, there was no detectable comprehensive evidence on higher rates of aneuploidy based on maturity status on the day of oocyte retrieval. As well, the correlation between embryo morphology on aneuploidy remains unclear. The aim was to evaluate the developmental and genetic integrity of human preimplantation embryos from rescue in-vitro matured MII stage oocytes as well as in vivo matured oocytes...

'Poor responders' is a term used to describe a subpopulation of IVF patients who do not respond well to ovarian stimulation with gonadotrophins. While there is no standard definition of a poor responder, these patients tend to be of advanced maternal age (≥40 years), have a history of poor ovarian response with conventional stimulation protocols, and/or have low ovarian reserve. Despite the heterogeneity of this patient group, there are characteristics and needs common to many poor responders that can be addressed through a holistic approach...

PURPOSE: During the transitional phase of premature ovarian insufficiency (POI), sporadic resumption of ovulation is possible because of fluctuation of hormonal levels but the chance of spontaneous pregnancy is low, and the main perspective of childbearing in these women is egg donation or adoption. The purpose of the study was to verify whether treatment with estrogens in POI patients in transitional phase could reduce FSH levels and to evaluate if this pre-treatment could improve reproductive outcomes of in vitro fertilization (IVF)...
