A comparison between short GnRH agonist and antagonist protocols in expected normal responder females following ICSI

Abstract

The selection of protocols in controlled ovarian stimulation during intracytoplasmic sperm injection affect the treatment outcomes. Both GnRH agonist and GnRH antagonist protocols are clinically utilized, therefore comparision of these protocols is important for the evaluation of their laboratory and clinical outcomes.To compares the short GnRH agonist and GnRH antagonist protocols effectiveness in expected normal responder females undergoing intracytoplasmic sperm injection (ICSI). Methods: A retrospective study was involved 60 women aged less than 35 with antimullerian hormone (AMH) more than 2.5 ng/ml. Participants women were assigned to either group1 short GnRH agonist protocol and group2 GnRH antagonist protocol. The outcomes measured including total oocyte, mature and immature oocytes, number and quality of embryo and pregnancy rate.The short GnRH agonist protocol group showed statistical significant benefit in oocyte yield (p- value 0.04), metaphase I (p- value 0.09), metaphase II (p- value 0.03), embryo number (p- value 0.04), embryo quality (p-value 0.01) and pregnancy rate in expected normal responder women compared to GnRHantagonist protocol. The short GnRHagonist protocol reveals favorable ICSI outcomes than antagonist protocol and may be better choice in expected normal responder women.
