Prevention of Ovarian Hyperstimulation Syndrome

Ovarian hyperstimulation syndrome (OHSS) is rare but most serious complication of ovarian stimulation. Symptoms are mainly related to increased capillary permeability leading to extravasation of fluid into extravascular compartment. Disease pathophysiology is linked to hCG (human chorionic gonadotropin) which acts through angiogenic molecule vascular endothelial growth factor (VEGF). There is r...

Prevention and Treatment of Ovarian Hyperstimulation Syndrome

Prevention and treatment of ovarian hyperstimulation syndrome.

The ovarian hyperstimulation syndrome (OHSS) is a potentially fatal condition with a pathophysiology that is not clearly understood. A shift in fluid from the extravascular space occurs, thought to be induced by cytokines and/or vascular endothelial growth factor. Human chorionic gonadotrophin (hCG), exogenous or endogenous, seems to be the triggering mechanism, resulting in early and late deve...

Prevention and management of ovarian hyperstimulation syndrome.

The Ovarian Hyperstimulation Syndrome (OHSS) represents one of the biggest nightmares of all physicians involved in Assisted Reproductive Technologies (ART). Every year, several hundreds of women are hospitalized and to date several deaths have been reported. The pivotal event in the development of OHSS is the disruption of capillary integrity that results in leakage of intravascular fluid and ...

Prevention of Ovarian Hyperstimulation Syndrome: A Review

The following review aims to examine the available evidence to guide best practice in preventing ovarian hyperstimulation syndrome (OHSS). As it stands, there is no single method to completely prevent OHSS. There seems to be a benefit, however, in categorizing women based on their risk of OHSS and individualizing treatments to curtail their chances of developing the syndrome. At present, both A...
