Predicting successful induction of oocyte maturation after gonadotropin-releasing hormone agonist (GnRHa) trigger.
STUDY QUESTION Are there factors predicting the number of total and mature oocytes retrieved after controlled ovarian hyperstimulation (COH) utilizing a gonadotropin-releasing hormone (GnRH) antagonist protocol and a GnRH agonist (GnRHa) to induce oocyte maturation? SUMMARY ANSWER Peak estradiol (E₂) level, post-trigger LH and progesterone and the magnitude of LH rise are independent predicto...
متن کاملIn vitro viability and secretory capacity of human luteinized granulosa cells after gonadotropin-releasing hormone agonist trigger of oocyte maturation.
OBJECTIVE To evaluate viability of luteinized granulosa cells obtained from patients triggered with either GnRH agonist or hCG and to assess the secretion of steroids and vascular endothelial growth factor (VEGF) by cultured luteinized granulosa cells in the presence or absence of hCG. DESIGN Prospective, randomized controlled trial. SETTING University-based fertility center. PATIENT(S) A...
متن کاملFinal Oocyte Maturation in Assisted Reproduction with Human Chorionic Gonadotropin and Gonadotropin-releasing Hormone agonist (Dual Trigger)
Final oocyte maturation with Human Chorionic Gonadotropin (hCG) and ovarian stimulation with Follicle Stimulation Hormone (FSH) combined with Gonadotrophin-releasing Hormone (GnRH) antagonist to block Luteinizing hormone (LH) surge is a standard procedure of in vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI). However, GnRH agonist has been replacing the use of hCG in certa...
متن کاملGonadotropin-releasing hormone agonist triggering of oocyte maturation in assisted reproductive technology cycles
Gonadotropin-releasing hormone agonists (GnRHa) have gained increasing attention in the last decade as an alternative trigger for oocyte maturation in patients at high risk for ovarian hyperstimulation syndrome (OHSS). They provide a short luteinizing hormone (LH) peak that limits the production of vascular endothelial growth factor, which is the key mediator leading to increased vascular perme...
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...
