introduction: the aim of this study was to evaluate the expression of pinopodes as animplantation marker after ovarian hyper stimulation and progesterone injection using scanningelectron microscopic studies. material and methods: three groups of nmri adult female mice were used in the experiment. the control group (group a) were untreated pseudopregnant mice. group b mice were made pseudopregna...

Background: Release of vascular endothelial growth factor (VEGF) by ovaries in response to HCG administration is one of the main mechanisms of ovarian hyper stimulation syndrome. Since Dopamine/dopamine receptor2 (Dp-r2) pathway activity -mediated by VEGF/ Vascular endothelial growth factor receptor 2 (VEGFR-2) signaling-, is associated with angiogenic events, dopamine agonists were used for th...

background: despite extensive progress in ivf techniques, one of the most difficult problems is the variability in the response to controlled ovarian hyperstimulation (coh). recent studies show the effects of individual genetic variability on coh outcome. objective: to evaluate the correlation between lhβ g1502a polymorphisms in exon 3 of the lh gene and ovarian response to coh. materials and m...

Background: Anti-Mullerian hormone (AMH) has been suggested as a marker of ovarian reserve and predictor of ovarian response to controlled ovarian hyper stimulation. The aim of this study is to determine the role of AMH in prediction of success ART cycles in patients with normal FSH serum levels. Materials and Methods: This prospective cohort study included 80 infertile women under 4o years, wh...

Objective Recently the laparoscopic ovarian drilling (LOD) has been used as a surgical treatment for ovulation in women with polycystic ovarian syndrome (PCOS), although its mechanism and outcomes are still unclear. This study was undertaken to evaluate the in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes in clomiphene-resistant women with PCOS who were treated with...

The GnRH analogue (agonist and antagonist GnRH) changed ovarian stimulation. On the one hand, it improved chances of pregnancy to obtain more oocytes and better embryos. This leads to an ovarian hyper-response, which can be complicated by the ovarian hyperstimulation syndrome (OHSS). On the other hand, the GnRH analogue can prevent the incidence of OHSS: GnRH antagonist protocols, GnRH agonist ...
