Live birth rate following endometrial preparation with daily versus depot GnRH agonist.

Gonadotrophin-releasing hormone agonist (GnRHa) is used to Frozen­thawed embryo transfer to artificially prepared endometrium (FET-APE). However, it is not known which of the depot and daily preparations is more effective. Our study to exclusively compare 5th day euploid single embryos transferred in FET-APE cycles using depot or daily injections of GnRHa to avoid any influences of oocyte or spermatozoa dependent factors on Beta Human Chorionic Gonadotrophin (BHCG) positivity and live birth rates (LBR). The results were similar. Since the results are similar, the depot GnRHa form can be preferred for ease of use. However, future studies on larger series and patients with different clinical characteristics may effects the results.
