OBJECTIVE To compare the outcomes of protocols for ovarian stimulation with recombinant hCG microdose, with GnRH agonists and antagonists for pituitary suppression. DESIGN Prospective nonrandomized clinical trial. SETTING A private assisted reproduction center. PATIENT(S) We studied 182 patients undergoing intracytoplasmic sperm injection (ICSI) cycles, allocated into two groups: GnRH ago...
The ovarian stimulation of poor responders still remains a challenging task for clinicians. There are numerous strategies that have been suggested to improve the outcome in poor responders but there is still no one pituitary down-regulation protocol that best suits all women with such condition. Traditional GnRH agonist flare and long luteal phase protocols do not appear to be advantageous. Red...

To review treatment options for poor-responding patients who are undergoing infertility treatment. Review article and case studies.A comprehensive determination of potential ovarian response for the poor-responding patient is important in the individualization of treatment options for these patients. Treatment options include both the microdose flare leuprolide acetate and GnRH antagonist stimu...
Few successful pregnancies after age 45 years with low ovarian reserve have been reported. We report a 46-year-old woman with basal FSH 20.36 mIU/mL and an antral follicle count of four obtained two embryos and delivered a healthy infant with IVF using a microdose GnRH-a flare-up protocol combined with GnRH-ant.
the microdose gnrh agonist (gnrh-a) flare protocol may have a particular value for previously poor responders in whom it has been observed to stimulate dramatic increases in serum fsh. the purpose of this study was to determine the effects of microdose gnrh-a in poor responders. this is a clinical trial with before and after design. this study was done in research and clinical center for infert...
Ovarian volume measurements have been recently shown to be predictive of response to ovarian stimulation. Women with small ovarian volumes, i.e. <3 cm(3), have a higher incidence of cycle cancellation, together with a lower peak oestradiol concentration, lower number of retrieved oocytes, and lower pregnancy rates, compared with women with larger ovarian volumes. We prospectively investigated w...
BACKGROUND This study compares the microdose flare-up protocol to the ultrashort gonadotropinreleasing hormone (GnRH) agonist flare combined with the fixed multidose GnRH antagonist protocol in poor responders undergoing ovarian stimulation. MATERIALS AND METHODS In this randomized clinical trial, 120 women who were candidates for assisted reproductive techniques (ART) and had histories of on...
BACKGROUND Microdose flare-up GnRH agonist and GnRH antagonist have become more popular in the management of poor ovarian responders (POR) in recent years; however, the optimal protocol for POR patients undergoing in vitro fertilization has still been a challenge. METHODS In this observational study design, two hundred forty four poor ovarian responders were retrospectively evaluated for thei...
OBJECTIVE To compare cost-effectiveness between pituitary down-regulation with a GnRH agonist (GnRHa) short regimen on alternate days and GnRH antagonist (GnRHant) multidose protocol on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcome. DESIGN Prospective, randomized. SETTING A private center. PATIENT(S) Patients were randomized into GnRHa (n = 48) and GnRHant (...
