GnRH agonist versus GnRH antagonist in oocyte donation cycles: a prospective randomized study.
BACKGROUND The specific role of LH in folliculogenesis and oocyte maturation is unclear. GnRH antagonists, when administered in the late follicular phase, induce a sharp decrease in serum LH which may be detrimental for IVF outcome. This study was performed to evaluate whether the replacement of GnRH agonist (triptorelin) by a GnRH antagonist (ganirelix; NV Organon) in oocyte donation cycles ha...
متن کاملGnRH agonist versus GnRH antagonist in assisted reproduction cycles: oocyte morphology
BACKGROUND The selection of developmentally competent human gametes may increase the efficiency of assisted reproduction. Spermatozoa and oocytes are usually assessed according to morphological criteria. Oocyte morphology can be affected by the age, genetic characteristics, and factors related to controlled ovarian stimulation. However, there is a lack of evidence in the literature concerning t...
متن کاملGnRH agonist and GnRH antagonist in intracytoplasmic injection cycles.
The long agonistic protocol for controlled ovarian hyperstimulation (COH) is effective and used most often, thus is considered the gold standard. Therefore any new regimen has to be compared in its results with those obtained with the long protocol. This report compares the efficacy of GnRH agonist and antagonist in a retrospective study of IVF/ICSI carried out in a tertiary teaching hospital f...

متن کاملP-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, ...
