GnRH agonist versus GnRH antagonist in poor ovarian responders: a meta-analysis

GnRH agonist versus GnRH antagonist in poor ovarian responders: a meta-analysis.

The aim of this meta-analysis was to compare the efficacy of gonadotrophin antagonist (GnRH-ant) versus GnRH agonist (GnRHa) as coadjuvant therapy for ovarian stimulation in poor ovarian responders in IVF/intracytoplasmic sperm injection cycles. Search strategies included on-line surveys of databases such as MEDLINE , EMBASE and others. A fixed effects model was used for odds ratio (OR) and eff...

Comparisons of GnRH antagonist versus GnRH agonist protocol in poor ovarian responders undergoing IVF.

BACKGROUND In view of the discrepancies about the GnRH antagonist (GnRH-ant) ovarian stimulation protocols having some potential advantages compared with the GnRH agonist (GnRH-a) protocols in poor ovarian responders IVF/ICSI, a meta-analysis of the published data was performed to compare the efficacy of GnRH-ant versus GnRH-a protocols for ovarian stimulation in IVF poor response patients. M...

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...

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

Comparison of long GnRH agonist versus GnRH antagonist protocol in poor responders

OBJECTIVE To compare long GnRH agonist with GnRH antagonist protocol in poor responders. MATERIALS AND METHODS Medical charts of 531 poor responder women undergoing in-vitro fertilization (IVF) cycle at Zeynep Kamil Maternity and Children's Hospital, IVF Center were retrospectively analysed. Those who received at least 300 IU/daily gonadotropin and had ≤3 oocytes retrieved were enrolled in th...
