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: the luteal phase defect is a common event following the ovarian stimulation. the aim of the present study was to evaluate the use of human chorionic gonadotropine (hcg) and progesterone hormones to improve the luteal phase defect. materials and methods: 60 mice were superovulated routinely with human menopausal gonadotropin (hmg) (7.5u) and hcg (10u). the mice were mated and divided...

 ABSTRACT Background: In order to evaluate the role ofketoconazole in the prevention of ovarian hyperstimulation syndrome (OHSS) in women with polycystic ovary syndrome (PCOS) undergoing ovarian stimulation with gonadotropins, a prospective, randomized, double-blind, placebo controlled study was done on one-hundred and nine PCOS women that had been refeiTed to be treated by gonadotropi...

Minimal stimulation in vitro fertilization (mini-IVF) consists of a gentle controlled ovarian stimulation that aims to produce a maximum of five to six oocytes. There is a misbelief that mini-IVF severely compromises pregnancy and live birth rates. An appraisal of the literature pertaining to studies on mini-IVF protocols was performed. The advantages of minimal stimulation protocols are report...

Correct controlled ovarian stimulation is of paramount importance in assisted reproductive technologies. Therefore, analysis of the ovarian reserve of the patient is mandatory to tailor the best ovarian stimulation regimen. When the ovarian reserve is reduced, the induction of a multifollicular growth remains a challenge. Several factors could be associated with reduced ovarian response. Howeve...
