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...

in vitro fertilization (ivf) and other assisted reproductive technologies present an enormous hope to couples with fertility difficulties. assisted reproductive technology is one of the risk factors that can result in anxiety in these couples. indeed, ivf-treatments cause a stress, for both the woman and her partner. the different stages of the ivf-procedure can affect the emotional life of the...

abstract 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...

BACKGROUND Given the controversies regarding the effectiveness of gonadotropin-releasing hormone (GnRH) antagonists in prevention of ovarian hyper stimulation syndrome stimulation, this study was designed to compare GnRH agonist protocol with GnRH antagonist protocol in patients who were candidate for assisted reproductive techniques (ARTs). MATERIALS AND METHODS This investigation was perfor...

discussion the presence of ohss in spontaneous pregnancy especially in familial pattern may lead us to evaluate some endogenous pathogenic factors. case presentation in this case report, we are going to present two cases of ohss occurring in spontaneously conceived pregnancies. one of the patients mentioned the history of this syndrome in her sister, and the other one confronted with this syndr...

Background Fertility preservation for female cancer patients prior to cancer therapy has emerged as an essential component of comprehensive patient care. In the US, approximately 6% of women diagnosed with invasive cancer between 2007 and 2011 that were under 45 years old. The incidence of cancers in reproductive age women signifies a need for fertility preservation options and this need is inc...

PCOS is still a problem in gynecology and infertility. Especially in ART the problem of PCOS patients is bigger and more highlighted. These patients are prone to over and under stimulation. Strategies to overcome hyper stimulation are: use of metformin, ovarian drilling, use of minimal stimulation, suppressing LH with use of OCP or GnRh analogues, use of GnRh antagonist in COH. But none of thes...

Multiple pregnancies and ovarian hyper stimulation syndrome (OHSS) are the most serious complications of ovarian stimulation and IVF. Indeed, they are more or less the only ones. OHSS can effectively be prevented in three stages: Before stimulation, during stimulation and at ET. Before stimulation patients should be assessed as to age, the ovarian follicular count and/or anti mullerian hormone ...
