GnRH Analogues in the Prevention of Ovarian Hyperstimulation Syndrome

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 agonist ...

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 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...

The Effectiveness of Cabergoline for the Prevention of Ovarian Hyperstimulation Syndrome

Type 2 receptors for vascular endothelial growth factor are believed to be involved in the pathophysiology of ovarian hyperstimulation syndrome (OHSS). The objective of this study was to examine the preventive effects of cabergoline on OHSS and its complications. The study is a non randomized clinical trial conducted in 2006-2008 on 75 patients, which were at risk of OHSS and underwent assisted...

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...
