GnRH agonist versus GnRH antagonist in oocyte donation cycles: a prospective randomized study.

Comparison between a GnRH antagonist and a GnRH agonist flare-up protocol in oocyte donors: a randomized clinical trial.

BACKGROUND Little information is available on the outcome of controlled ovarian hyperstimulation (COH) using GnRH antagonist in oocyte donation cycles especially in comparison with the short GnRH agonist protocol. This study was aimed at comparing the two stimulation protocols in oocyte donation (OD) cycles. METHODS A total of 113 donors randomly received COH using either GnRH antagonist or G...

P-149: GnRH Antagonist versus Agonist in Normoresponders Undergoing ICSI: A Randomized Clinical Trial in Iran

Background: General concern is that the pregnancy rate is higher with GnRH-agonist as a protocol of pituitary suppression. GnRH-antagonist protocol provides a shorter period of administration and an easy flexible protocol. In this study, the outcomes of GnRH agonist and antagonist in ICSI cycles are compared in normo responder patients. Materials and Methods: In this randomized clinical trial, ...

Microdose GnRH Agonist Flare-Up versus Ultrashort GnRH Agonist Combined with Fixed GnRH Antagonist in Poor Responders of Assisted Reproductive Techniques Cycles

Flexible Multi-dose GnRH Antagonist versus Long GnRH Agonist Protocol in Poor Responders: A Randomized Controlled Trial

Background To compare a flexible, multi-dose GnRH antagonist protocol with a long GnRH .agonist protocol in poor respo MaterialsAndMethods A randomized clinical trial of 70 poor responder patients (35 patients in GnRH antagonist protocol and 35 patients in long GnRH agonist protocol) was performed at Royan Institute, Tehran, Iran. Both groups were given a fixed dose of human menopausal gonadotr...

P-160: A Comparative Study of Luteal Estradiol Pre-Treatment in GnRH Antagonist Protocols AndIn Micro Dose Flare Protocols for Poor Responding Patients

Background: This study aims to verify if luteal estradiol pre-treatment improves IVF/ICSI outcomes in a GnRH antagonist protocol as compared to a micro dose GnRH agonist protocol in poor-responding patients. Materials and Methods: A total of 116 IVF/ICSI cycles were included in this prospective randomized clinical trial. The selected women were randomly assigned to receive an estradiol pre-trea...
