Management of severe ovarian hyperstimulation syndrome (OHSS) includes hospitalization for fluid and electrolyte management. Abdominal paracentesis is also used as minimally invasive form of management in selected cases of severe OHSS following ovulation induction. However, if pregnancy ensues, the syndrome persists for a longer period, and the clinical manifestations of severe OHSS could mask ...

Ovarian hyperstimulation syndrome (OHSS) is a potentially life‑threatening, iatrogenic complication that occurs during assisted reproduction. Polycystic ovarian syndrome (PCOS) significantly increases the risk of OHSS during controlled ovarian stimulation. Therefore, a more effective early prediction technique is required in PCOS patients. Quantitative proteomic analysis of serum proteins indic...

Changes in CA602 and CA546, two carbohydrate-related antigens newly established in our institute, were evaluated during the course of in-vitro fertilization and embryo transfer. The concentration of CA602, an antigen with characteristics similar to those of CA125, did not change substantially until embryo transfer. In patients with clinical evidence of ovarian hyperstimulation syndrome (OHSS), ...

Severe ovarian hyperstimulation syndrome (OHSS) is a rare but potentially fatal condition associated with conventional IVF treatment. It is found predominantly in women with polycystic ovaries who have an exaggerated response to exogenous FSH, leading to a large number of follicles and an overproduction of vascular endothelial growth factor with resultant excessive increases in vascular permeab...

Ovarian hyperstimulation syndrome (OHSS) is potentially life-threatening complication associated with ovarian induction. OHSS is a very rare event in spontaneous pregnancies, most often in situations of multiple or molar gestations, hypothyroidism or polycystic ovary syndrome. We describe a patient with naturally conceived pregnancy associated with spontaneous OHSS complicated by hyperthyroidis...

BACKGROUND Gonadotropin-releasing hormone (GnRH) agonist triggering plus 1,500 IU human chorionic gonadotropin (hCG) supplementation protocol was previously claimed effective in reducing the ovarian hyperstimulation syndrome (OHSS) incidence in high responders. METHODS This retrospective study included women with polycystic ovarian (PCO) morphology who were at high risk of OHSS and were given...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of ovarian stimulation, and the pathophysiological mechanisms that trigger the syndrome remain unknown. HCG increases serum vascular endothelial growth factor (VEGF) concentrations, and VEGF modulates transendothelial permeability via endothelial adherens junctions, a downstream target for VEGF signalling. We exam...

Withholding gonadotrophin administration (coasting) may prevent severe ovarian hyperstimulation syndrome (OHSS). To ascertain the effectiveness of this protection a cohort of 252 consecutive in-vitro fertilization (IVF) or IVF with intracytoplasmic sperm injection (ICSI) cycles was studied. Twenty women with exaggerated response were treated with coasting. Despite coasting, four patients develo...

Vascular endothelial growth factor (VEGF) is stated to be a possible promoter of the development and the severity of ovarian hyperstimulation syndrome (OHSS). The secretion of VEGF in granulosa cells seems to be human chorionic gonadotrophin (HCG) dependent. In this prospective study, the data of 10 patients suffering from severe OHSS with ascites and pleural effusions (haematocrit, fluid balan...

Two cases of women who developed internal jugular vein (IJV) thrombosis associated with ovarian hyperstimulation syndrome (OHSS) are reported in this article. There are 27 cases of IJV thrombosis associated with in vitro fertilisation (IVF) reported in the literature, and in 78% of cases, this outcome was following OHSS. The hypercoagulable state of OHSS increases the risk of venous thromboembo...
