OBJECTIVE: Our goal was to assess a novel role for GnRH-agonist as a supplement in luteal phase. GnRH-agonist receptors are present in the endometrium and the ovaries. Furthermore, the corpus luteum function may improve with GnRH-agonist induced endogenous flare with pituitary hormones. In vitro, GnRH-agonists have improved mouse embryo developement. Recent studies have demonstrated improved implantation rate with the use of a single dose GnRH-agonist 6 days after oocyte retreival in an IVF cycle (Tesarik, Hum Reprod, 2006,21: 2572-9). Our objective was to evaluate the impact of a daily GnRH-agonist at the time of implantation (Days 5-7 following retreival) on IVF outcomes in antagonist cycles.

DESIGN: Retrospective analysis.
DESIGN: Retrospective analysis.

CONCLUSIONS: Mid luteal phase support with GnRH-agonist, around the days of implantation appears to yield favorable outcomes in IVF cycles using GnRH-antagonists for ovarian stimulation. A large randomized prospective controlled trial will need to be conducted in order to confirm these findings.
