Clinical outcome of using ganirelix acetate versus a 4-day follicular phase leuprolide acetate protocol in unselected women undergoing in vitro fertilization.

Abstract:

OBJECTIVE:To compare the clinical outcome of controlled ovarian hyperstimulation (COH) in unselected patients undergoing IVF using multidose ganirelix acetate versus 4 days of administration of leuprolide acetate. DESIGN:Retrospective cohort study. SETTING:A fertility and IVF center. PATIENT(S):Two hundred forty-seven women who underwent COH-IVF between April 1, 1999, and January 30, 2001. INTERVENTION(S):Pituitary suppression according to a 4-day follicular phase leuprolide acetate protocol (236 women) or a multidose ganirelix acetate regimen (133 women). MAIN OUTCOME MEASURE(S):Amount of gonadotropin used, days of stimulation, cancellation rate, number of oocytes retrieved, implantation rate, and clinical pregnancy rate. RESULT(S):Compared with leuprolide acetate recipients, ganirelix recipients required significantly less gonadotropin and the mean day of hCG administration was 4 days earlier. Among women younger than 35 years of age, the implantation rate (15% vs. 6%) and the clinical pregnancy rate per initiated and transferred cycle (27% vs. 12% and 32% vs. 15%, respectively) were significantly higher in the ganirelix group than the leuprolide acetate group. CONCLUSION(S):Compared with a 4-day leuprolide acetate protocol, COH-IVF using a multidose ganirelix acetate protocol reduces treatment duration and amount of gonadotropin used. In younger women, the latter protocol is associated with significantly better pregnancy and implantation rates.
