the effect of short term usage of gnrh antagonist as pretreatment on superovulation in goats was evaluated. statistical analysis was performed using t-test and showed that usage of gnrh antagonist as pretreatment can improve number of recovered embryos (p0.05). this study showed that usage of gnrh antagonist can improve superovulatory response in term of embryo recovery in goats .this study sho...

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, ...

Objective Coasting can reduce the ovarian hyperstimulation syndrome (OHSS) risk in ovulation induction cycles before intracytoplasmic sperm injection (ICSI). This study aimed to investigate the effect of gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols to controlled ovarian hyperstimulation (COH) cycles with coasting on the parameters of ICSI cycles and the outcome. M...

Background The optimal stimulation protocol for poor responder patients is a therapeutic challenge. GnRH antagonist protocol has been proposed as a potentially proper option for poor responders. Nevertheless, there is no significant difference in terms of clinical pregnancy and cancellation rates be tween the GnRH antagonist and agonist cycles. Therefore, this subset of patients might be the be...

background: gnrh agonist and antagonist were developed to control the premature release of lh surge. there is some difference between two protocols. objective: we compared the outcome of frozen-thawed embryo transfer in infertile women who used gnrh agonist or antagonist protocol for previous coh cycle and evaluation of any adverse effect of gnrh antagonist on oocyte and embryo. materials and m...

objective: coasting can reduce the ovarian hyperstimulation syndrome (ohss) risk in ovulation induction cycles before intracytoplasmic sperm injection (icsi). this study aimed to investigate the effect of gonadotropin-releasing hormone (gnrh) agonist and gnrh antagonist protocols to controlled ovarian hyperstimulation (coh) cycles with coasting on the parameters of icsi cycles and the outcome. ...

background: the purpose of present study was to evaluate the role of pre-ovulatory gnrh agonist therapy on ivf outcomes in gnrh antagonist cycles. methods: in this prospective study we recruited 100 infertile women undergoing ivf cycles with gnrh antagonists. the patients were assigned to two groups: group a (the study group, n=42) were assigned for receiving hcg+triptorelin for the final oocyt...

objective: this study was conducted to compare the results of fixed versus flexible gnrh antagonist protocols in controlled ovarian stimulation for intra cytoplasmic sperm injection (icsi) in patients with pcos. materials and methods: a randomized clinical trial was performed on 100 pcos women, who were admitted to a tertiary infertility clinic and were candidate for ivf/icsi. they were divided...

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...

background: gnrh agonist administration in the luteal phase has been suggested to beneficially affect the outcome of intracytoplasmic sperm injection (icsi) and embryo transfer (et) cycles. this blind randomized controlled study evaluates the effect of gnrh (gonadotropine releasing hormone) agonist administration on icsi outcome in gnrh antagonist ovarian stimulation protocol in women with 2 or...
