Use of progestins to inhibit spontaneous ovulation during ovarian stimulation: the beginning of a new era?
Publication date: Available online 29 March 2019Source: Reproductive BioMedicine OnlineAuthor(s): Antonio La Marca, Martina CapuzzoAbstractAdvances in oocyte and embryo cryopreservation for assisted reproduction prompted new approaches to ovarian stimulation. Attention has been paid to progesterone and its derivatives to block the LH surge, as oocyte vitrification removes possible harmful effects of progestins on endometrial receptivity. This review summarizes the current status of progestin use to inhibit ovulation during ovarian stimulation compared with conventional ovarian stimulation. Progestin-primed ovarian stimulat...

ConclusionsCurrent quality control protocols may not be sensitive enough to identify low presence of peroxides which, if undetected, can increase over time and become potentially harmful during gamete and embryo culture. The different parameters established in our study allow to optimize the sensitivity of the MEAs to specifically detect peroxides in mineral oil samples, prior to their release into the market and their broad use in human IVF.

Women's health providers’ perspectives on preimplantation genetic testing
ConclusionsIn a sample of women's health providers across multiple different OB/GYN specialties, there was an overall supportive response towards PGT use for a variety of common indications. Infertility specialists were the most supportive of PGT use, which may reflect the familiarity these providers have with this procedure. There was an overwhelmingly non-supportive response to the use of PGT for non-disease related indications. The percentage of medical professionals working in women's health without prior knowledge of PGT (22.5%) is higher than expected, identifying the need for more education regarding the availabilit...

Inheritance of imbalances in recurrent chromosomal translocation t(11;22): clarification by PGT-SR and sperm-FISH analysis
ConclusionsThese findings highlight the divergence that may exist between meiotic segregation and post-zygotic selection. Post-zygotic selection would be responsible for the elimination of unbalanced embryos derived from the adjacent-1 segregation mode. The combined action of several factors occurs at the beginning of post-zygotic selection. Genetic counselling must consider the risk of a birth related to the adjacent-1 segregation mode, irrespective of the sex of the translocation carrier. These results will allow deeper understanding of the PGT results of t(11;22) carriers, which often include a high number of aneuploid ...
