Serum oestradiol and progesterone concentrations were examined for up to 7 days after withholding gonadotrophins whilst continuing pituitary down-regulation in 15 women at serious risk of severe ovarian hyperstimulation syndrome (OHSS) (serum oestradiol >6000 pg/ml and >15 follicles per ovary). Serum oestradiol concentrations rose on day 1 of coasting in all but two of the 15 women before falli...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) in IVF/ICSI cycles may occur either as an early (early onset) or a late pattern (late onset). This observational study was designed to identify whether the onset pattern of OHSS is associated with the occurrence of pregnancy and the early pregnancy outcome. METHODS Among 4376 consecutive IVF/ICSI cycles, 113 patients were hospitalized for OH...

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...

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of controlled ovarian hyperstimulation (COH) protocols performed in women undergoing assisted reproductive technologies. Overstimulation of the ovaries results in the overproduction of vasoactive cytokines and mediators by the ovaries, thereby causing a generalized capillary leak and acute shift of protein-rich fluid from th...

Objectıve: Spontaneous OHSS (sOHSS) is an extremely rare condition in natural conceived pregnancy, it’s most often seen in cases of multiple or molar gestations, hypothyroidism and polycystic ovary syndrome. Severe form is a rare entity in singleton pregnancy with spontaneous ovulation and may cause laparotomy because of misdiagnosis such as ovarian tumors or severe complications. We report a r...

background: ovarian hyperstimulation syndrome (ohss) is a recognized complication of ovulation induction, occurring in 1-10% of ivf and embryo transfer cycles. while mild ohss is of no clinical relevance, severe ohss is a life threatening complication. however, the efficacy of prevalent treatments appeared to be limited. we developed a continuous autotransfusion system with an ultrafiltration i...

background: the purpose of this study was to compare the three different strategies, intravenous (iv) hydroxylethyl starch (hes), iv human albumin (ha), and oral cabergoline (cb) in the prevention of ovarian hyperstimulation syndrome (ohss). materials and methods: in this prospective randomized clinical trial, 91 women at high risk of developing ohss were allocated into the three groups, group ...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is an important and dangerous aspect of assisted reproduction techniques. Although elective cryopreservation of all embryos can prevent pregnancy-induced late OHSS, it cannot prevent early OHSS, which is induced by hCG administration. METHODS We undertook this trial to assess the efficacy with which the combined oral administration of angiot...

Background: Infertility is becoming global health issue, which affects multiple aspects of human life in both genders . Medical induction ovulation with clomiphene citrate has been first line treatment infertility since 1962 Discrepancy rate and pregnancy along complication most the infertile patients raises question for alternative Increased risk (OHSS) ovarian hyperstimulation syndrome associ...

BACKGROUND Many theories regarding the pathophysiology leading to ovarian hyperstimulation syndrome (OHSS) have been proposed and tested. Increased erythrocyte aggregation is associated with capillary slow flow and tissue hypoxaemia. We performed this study in order to assess the degree of erythrocyte aggregation in the peripheral blood of individuals with OHSS and undergoing controlled ovarian...
