Individual luteolysis pattern after GnRH-agonist trigger for final oocyte maturation
Final oocyte maturation using GnRH-agonist trigger in a GnRH-antagonist protocol is increasingly common, as ovarian hyperstimulation syndrome is almost completely avoided. However, this approach might lead to reduced pregnancy rates due to severe luteolysis. This proof of concept study evaluated the extend of luteolysis by measuring progesterone levels 48 hours after oocyte retrieval in 51 pati...
متن کاملGnRHa to trigger final oocyte maturation: a time to reconsider.
Recently GnRH antagonist protocols for the prevention of a premature LH surge were introduced, allowing final oocyte maturation to be triggered with a single bolus of a GnRH agonist (GnRHa). GnRHa is as effective as hCG for the induction of ovulation, and apart from the LH surge a FSH surge is also induced. Until recently, prospective randomized studies reported a poor clinical outcome when GnR...
متن کاملComparison of Oocyte Maturation Trigger Using Follicle Stimulating Hormone Plus Human Chorionic Gonadotropin versus hCG Alone in Assisted Reproduction Technology Cycles
Objective The success rates of assisted reproduction technology (ART) could be developed with the improvement of ovarian stimulation protocols as well as the optimization of final oocyte maturation. The goal of this study was to compare oocyte maturation, fertilization and pregnancy rates among women with concomitant FSH administration at the time of hCG trigger and the hCG trigger alone. Mater...
متن کاملCo-administration of GnRH-agonist and hCG for final oocyte maturation (double trigger) in patients with low number of oocytes retrieved per number of preovulatory follicles-a preliminary report
BACKGROUND Recently, the co-administration of GnRH agonist and hCG for final oocyte maturation- 40 and 34 hours prior to OPU, respectively (double trigger) was suggested as the treatment of genuine empty follicle syndrome. In the present study, we aim to evaluate whether the double trigger improves the number of oocytes retrieved in patients with low (<50%) number of oocytes retrieved per numbe...
