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: since increased lh in the early follicular phase in pcos patients especially in gnrh antagonist protocol could be associated with reduced oocyte quality and pregnancy and impared implantation. the current study was conducted to determine art outcomes in gnrh antagonist protocol (flexible) and long gnrh agonist protocol and compare them with adding gnrh antagonist in gnrh antagonist ...

objective: to compare the pregnancy outcomes achieved by in vitro fertilization (ivf) between minimal stimulation and conventional antagonist protocols in poor ovarian responders (pors). materials and methods: in this randomized controlled trial, 77 pors undergoing ivf were selected and divided into two groups. first group was the minimal stimulation group (n = 42) receiving 100 mg/day clomiphe...

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. objective: 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 clini...

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, ...

background: to compare a flexible, multi-dose gnrh antagonist protocol with a long gnrh .agonist protocol in poor respo materials and methods: 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 gona...

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...

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...

background: premature luteinization during in vitro fertilization was commonly happened before the introduction of gnrh analogues. high level of unwanted progesterone is associated with adverse pregnancy outcome and is thought to be induced by inappropriate lh elevation.objective: to evaluate the progesterone level on the day of human chorionic gonadotropin (hcg) triggering in gnrh agonist and ...
