Background Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication, which can cause high morbidity and mortality. Use of gonadotropin releasing hormone (GnRH) agonist instead of human chorionic gonadotropin (hCG) in GnRH antagonist cycles causes luteinizing hormone surge by GnRH stimulation which reduces the risk of OHSS by reducing the total amount of gonadotropin; however, ther...

BACKGROUND Serum concentrations of antimullerian hormone (AMH) correlate with ovarian response during assisted reproduction treatment (ART) cycles. OBJECTIVE This retrospective study attempted to evaluate the selection of ovarian stimulation protocols based on serum AMH levels in patients and its impact on the results of ART. MATERIALS AND METHODS Based on AMH levels, the patients with tuba...

background: the ability of the ovary to respond to exogenous gonadotrophin stimulation and development of several follicles is essential in assisted reproductive technology. neither age and regularity of menses nor follicular phase fsh and estradiol concentrations are reliable predictors of ovarian response. day 3 serum inhibin-b level, during induction ovulation, has been proposed as a predict...

BACKGROUND Insulin-like growth factors (IGF) and their binding proteins (IGFBP) play a major role in the autocrine and paracrine regulation of folliculogenesis. This is the first study that has compared follicular fluid (FF) IGF-I, IGF-II, IGFBP-3, IGFBP-4 and pregnancy-associated plasma protein (PAPP)-A concentrations, and their ratios, to investigate whether there was any difference in the in...

pituitary suppression by depot gnrh agonist may be excessive for ovarian stimulation. this study compares the efficacy of a single half-dose depot triptorelin and reduced-dose daily buserelin in a long protocol icsi/et. methods: a total of 182 patients were randomized into two groups using sealed envelopes. pituitary desensitization was obtained in group 1 (91 patients) with half-dose (1.87 mg)...

background: determination of oocyte and embryo quality are one of the most important goals in ivf. anti-mullerian hormone (amh) is secreted by the ovarian granulosa cells into blood flow and follicular fluid. follicular fluid anti-mullerian hormone level is probably a marker of activity of granulose cells. objective: to evaluate whether high level of follicular fluid anti-mullerian hormone leve...

The aim of the present study was to gain a better understanding role brain-derived neurotrophic factor (BDNF) and dopamine D3 receptors in effects chronic methamphetamine (METH) on prepulse inhibition (PPI), an endophenotype psychosis. We compared effect three-week adolescent METH treatment protocol regulation PPI wildtype mice, BDNF heterozygous mice (HET), receptor knockout (D3KO), double-mut...
