This study reports 21 IVF cases with excessive ovarian response, who received gonadotrophin-releasing hormone agonist (GnRHa) triggering for final oocyte maturation, followed by a human chorionic gonadotrophin (HCG)-based, progesterone-free, luteal support, individually timed ('luteal coasting') according to endogenous luteal progesterone concentrations. One patient developed a brief early-onse...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is a serious and potentially fatal complication of ovarian stimulation which affects 1% to 14% of all in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) cycles. A number of clinical studies with conflicting results have reported on the use of plasma expanders such as albumin, hydroxyethyl starch (HES), mannitol, polygeline...

OBJECTIVE To report the management of a rare case of ovarian hyperstimulation syndrome (OHSS) induced by tamoxifen therapy for breast cancer in a 50-year-old woman. DESIGN Case report. SETTING Gynecology outpatient department of a university hospital. PATIENT(S) A 50-year-old premenopausal patient with a history of breast cancer was prescribed adjuvant treatment with tamoxifen. INTERVEN...

OBJECTIVE Elevated levels of C-reactive protein (CRP) were found recently to be a crucial marker for cardiovascular disease. This protein might have a role in endothelial cell activation, vascular damage and a thrombotic tendency. We sought to determine whether concentrations of CRP are altered in women with controlled ovarian hyperstimulation (COH) or hyperstimulation syndrome (OHSS). DESIGN...

Ovarian hyperstimulation syndrome (OHSS) is a dangerous and sometimes life-threatening complication of ovulation induction with exogenous gonadotrophins. While many complications of severe OHSS are recognized we have only identified one review detailing neurological problems. This report concerns a 32-year-old patient with bilateral tubal blockage who achieved her first pregnancy following in-v...

Fifty women with polycystic ovaries took part in a prospective randomized study. All women required treatment by in-vitro fertilization (IVF) for reasons other than anovulation. They had all previously undergone ovarian stimulation with gonadotrophin therapy which had failed to result in pregnancy or had been abandoned due to high risk of developing ovarian hyperstimulation syndrome (OHSS). Twe...

The purpose of this review is to analyze current medical strategies in the prevention of ovarian hyperstimulation syndrome (OHSS) during ovarian stimulation for in vitro fertilization. Owing to contemporary preventive measures of OHSS, the incidence of moderate and severe forms of the syndrome varies between 0.18% and 1.40%. Although none of medical strategies is completely effective, there is ...

Abstract Background Blood coagulation has been associated with ovulation and female infertility. In this study, the expression of tissue factor system was examined during in immature rats; correlation between ovarian hyperstimulation syndrome (OHSS) evaluated both rats human follicular fluids. Methods Ovaries were obtained at various times after chorionic gonadotropin (hCG) injection to investi...

OBJECTIVE To study reactivity of the ovarian vascular bed to noradrenaline and carbachol during an experimentally induced ovarian hyperstimulation syndrome (OHSS) in rabbits. MATERIALS AND METHODS Rabbits were treated with human menopausal gonadotropin (75 IU) daily for 6 days, followed by human chorionic gonadotropin (2,500 IU) to induce OHSS. The ovarian vascular bed was isolated and perfus...

ART is proven of great help to all the infertile couples anxious to get pregnant , but is not free of side effects and complications. OHSS one of the most important complication especially in cases of PCOS. Ovarian hyperstimulation syndrome (OHSS) is a potentially fatal complication of ovarian stimulation. The incidence has been estimated at 3 to 6% for moderate and 0.1 to 2% for severe OHSS. T...
