Study Question: Is there a difference in clinical pregnancy rates (CPRs) in good prognosis patients after single embryo transfer (SET) on Day 5, in case of stable culture at 36.6°C or 37.1°C?
Summary Answer: CPR (with heartbeat at 7 weeks) after blastocyst transfer do not differ after culturing at 36.
Purpose: To identify the sperm preparation procedure that selects the best sperm population for medically assisted reproduction.
Methods: Prospective observational study comparing the effect of four different sperm selection procedures on various semen parameters. Unused raw semen after routine diagnostic analysis was split in four fractions and processed by four different methods: (1) density gradient centrifugation (DGC), (2) sperm wash (SW), (3) DGC followed by magnetic activated cell sorting (MACS), and (4) using a sperm separation device (SSD).
Mature oocyte vitrification is the standard of care to preserve fertility in women at risk of infertility. However, ovarian tissue cryopreservation (OTC) is still the only option to preserve fertility in women who need to start gonadotoxic treatment urgently or in prepubertal children. During ovarian cortex preparation for cryopreservation, medullar tissue is removed.

Summary Answer: There is a statistically significant diurnal variation of serum P on the day of a FET in an mNC protocol.
What Is Known Already: In recent years, the proportion of FET cycles has increased dramatically. To further optimize pregnancy outcomes after FET, recent studies have focused on serum luteal P levels in both natural and artificially prepared FET cycles.
Article Synopsis
- The study looked at whether starting hormone treatment later than usual could still give the same number of eggs for egg donors.
- Two groups were tested: one starting early and one starting late, with 84 women in total.
- Results showed that both groups produced about the same number of eggs, but the early group used fewer hormones, took less time, and cost more money for medication.
