Study on the Outcome. of Transfer of Frozen-Thawed Embryos In Artificially Prepared Cycles with or without Prior Gonadotrophln Releasing Hormone Agonist Treatment

摘要

This study was performed to compare the outcome of frozen-thawed embryo transfer (FER) using two treatment protocols, i.e. the pituitary suppression with gonadotrophin releasing hormone agonist (GnRHa) followed by hormone replacement (group A) or the hormone replacement without prior pituitary suppression (group B). The group A (n= 34) and group B (n=37) were comparable in relation to clinical profile and laboratory results. Statistically significant difference was not observed in pregnancy tests positive women from both the protocols (20.6% in group A and 29.7% in group B). The clinical pregnancy rate in group B (27.0%) though higher than that of group A (14.7%) this difference was not statistically significant. Results concluded that FER with or without pituitary down regulation using GnRHa yields similar results.
