The Use of GnRH Agonist Trigger for Final Follicle Maturation in Women Undergoing Assisted Reproductive Technologies: A Prospective Randomized Controlled Trial

Brief Summary

Detailed Description

Follicle maturation triggering is the final differentiation process of an immature egg before fertilization, either in normal or stimulated ovarian cycles in assisted reproductive techniques. This step has traditionally been accomplished by the administration of human chorionic gonadotropin (hCG) trigger which mimics LH activity. However, hCG is a primary cause of severe ovarian hyperstimulation syndrome (OHSS) in women and appears to initiate the complex cascade that leads to the development of serious medical complications. Numerous strategies have been suggested to prevent OHSS; one of these is the administration of a gonadotropin releasing hormone (GnRH) agonist trigger instead of hCG. Despite a high safety profile, the GnRH agonist trigger of follicle maturation was found to be associated with a decreased probability of clinical and ongoing pregnancy rates and very high miscarriage rates. A profoundly deficient luteal phase is believed to be the cause of compromised reproductive outcome. Our personal clinical practice at the AUBMC Fertility Center seems to indicate that a novel GnRH agonist administration protocol is associated with a comparable reproductive performance to standard hCG trigger. In this study, we aim to validate the above clinical impression and assess associated parameters of success. Therefore, a prospective comparative randomized controlled trial will be performed in order to investigate the effect of three repeated doses of GnRH agonist trigger "Triptorelin" accompanied by intensive Luteal Support on the ongoing pregnancy outcome in women who are hyper-responders to ovarian stimulation when undergoing assisted reproductive technology.
