Comparison of GnRh Agonist Microdose Flare Up and GnRh Antagonist/Letrozole in Treatment of Poor Responder Patients in Intra Cytoplaspic Sperm Injection: Randomized Clinical Trial

Comparison of GnRh Agonist Microdose Flare Up and GnRh Antagonist/Letrozole in Treatment of Poor Responder Patients in Intra Cytoplaspic Sperm Injection: Randomized Clinical Trial.

BACKGROUNDS the prevalence of infertility is up to 10 to 15 % which 9 to 24 % of them are Poor Ovarian Responders (POR). This study was designed to compare two methods of GnRH Agonist Microdose Flareup (MF) and GnRH Antagonist/Letrozole (AL) in treatment of these patients. METHODS & MATERIALS this randomized clinical trial study consisted of 123 patients. In the first step of treatment in bot...

Microdose Flare-up Gonadotropin-releasing Hormone (GnRH) Agonist Versus GnRH Antagonist Protocols in Poor Ovarian Responders Undergoing Intracytoplasmic Sperm Injection

BACKGROUND Microdose flare-up GnRH agonist and GnRH antagonist have become more popular in the management of poor ovarian responders (POR) in recent years; however, the optimal protocol for POR patients undergoing in vitro fertilization has still been a challenge. METHODS In this observational study design, two hundred forty four poor ovarian responders were retrospectively evaluated for thei...

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

microdose flare-up gonadotropin-releasing hormone (gnrh) agonist versus gnrh antagonist protocols in poor ovarian responders undergoing intracytoplasmic sperm injection

background: microdose flare-up gnrh agonist and gnrh antagonist have become more popular in the management of poor ovarian responders (por) in recent years; however, the optimal protocol for por patients undergoing in vitro fertilization has still been a challenge. methods: in this observational study design, two hundred forty four poor ovarian responders were retrospectively evaluated for thei...

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...
