background: the differential efficacy between long gnrh agonist with antagonist can partly be due to the preexisting differences in the early antral follicles before ovarian stimulation. objective: to compare the effect of pretreatment by estradiol with gnrh antagonist on antral follicular size coordination and basal hormone levels in gnrh antagonist protocol. materials and methods: on cycle da...
OBJECTIVE We compared the assisted reproductive technology (ART) outcomes among infertile women with polycystic ovary syndrome (PCOS) treated with IVM, conventional IVF, GnRH agonist, and GnRH antagonist cycles. METHODS The prospective study included a total of 67 cycles in 61 infertile women with PCOS. The women with PCOS were randomized into three IVF protocols: IVM/IVF with FSH and hCG pri...
background: polycystic ovarian syndrome (pcos) patients are prone to premature lh surge and ovarian hyperstimulation syndrome (ohss). long gnrh analogue protocol and gnrh antagonist protocol are two methods utilized for induction ovulation in patients undergoing ivf/icsi. objective: the aim of this study was to compare the effects of gnrh agonists and antagonists in pcos patients. materials and...
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...
OBJECTIVE To evaluate the double-stimulation protocol efficacy over conventional ovarian stimulation in recovering a more adequate number of oocytes and increase the number of embryos to be transferred or to be genetically analyzed. METHODS A retrospective and comparative study with 13 patients who underwent unsuccessful in vitro fertilization (IVF) cycles with a conventional antagonist ovari...
OBJECTIVE To identify whether women with poor ovarian response may benefit from treatment with corifollitropin alfa in a GnRH antagonist protocol. DESIGN Retrospective pilot study. SETTING University-based tertiary care center. PATIENT(S) Poor ovarian responders fulfilling the Bologna criteria developed by European Society for Human Reproduction and Embryology Consensus Group. INTERVENT...
Abstract Study question Is there an advantage for modified flare/ GnRH antagonist protocol in comparison to oocyte cryopreservation cycles? Summary answer Modified is at least as good cycles, potentially improving maturity rate subgroup of patients. What known already Ultrashort flare agonist (GnRHa)/GnRH -antagonist offer benefits stimulatory effect repeated microdose on endogenous FSH and the...
background: determination of oocyte fertilization and embryo quality are one of the most important purposes in art cycles. follicular fluid provides an important microenvironment for development of oocytes and some biochemical characteristics of the follicular fluid, such as pregnancy-associated plasma protein-a (papp-a), may play an important role in prediction of success rate of art. objectiv...
GnRH antagonists have been used with increasing frequency in assisted reproduction treatments over the past few years and have been associated with quicker and more profound LH suppression and shorter treatment cycles than conventional GnRH agonists. Usually, these are commenced on day 6 of FSH stimulation without allowing for patient variation in response to treatment. The study was aimed at i...
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...
