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...
In the controlled ovarian hyperstimulation (COH) cycle of the in vitro fertilizationembryo transfer (IVF-ET) therapy, the clinicians observe the patients’ responses to gonadotropin dosages through closely monitoring their physiological states, to balance the trade-off between pregnancy rate and ovarian hyperstimulation syndrome (OHSS) risk. In this paper, we model the clinical practice in the C...
BACKGROUND Ovarian hyperstimulation syndrome (OHSS) typically occurs when ovaries are primed with FSH/LH and subsequently exposed to hCG. The ultimate pathophysiological step underlying this clinical picture is increased vascular permeability (VP). METHODS A search of the literature was carried out using PubMed and the authors' files. RESULTS In rodents and humans, the expression of vascula...
The objective of this study was to examine the correlation between both midfollicular FSH/LH ratio and number(s) of follicles with ovarian hyperstimulation syndrome (OHSS) in patients with polycystic ovarian syndrome (PCOS). This was carried out in IVF unit at Mirza Kouchak Khan Hospital. To induce ovulation, PCOS patients were stimulated with gonadotropines. Fifty four PCOS patients with norma...
BACKGROUND Ovarian hyperstimulation syndrome (OHSS), a complication of ovarian stimulation, has various adverse effects on both pregnant women and their offspring. However, whether OHSS will affect intellectual ability in offspring is still unknown. METHODS We recruited 86 Chinese children born to OHSS women and 172 children conceived with non-OHSS In Vitro Fertilization (IVF) in this cohort ...
BACKGROUND Compared with the general population, cancer patients have a higher risk of venous thromboembolism as well as arterial thrombotic events such as stroke, myocardial infarction and peripheral arterial embolism. Therefore a possible concern for women with malignancies undergoing ovarian stimulation for fertility preservation is the increased risk of venous or arterial thrombosis. METH...
Ovarian hyperstimulation syndrome (OHSS) is a rare iatrogenic complication of ovarian stimulation occurring during the luteal phase or during early pregnancy. Fortunately, the reported prevalence of the severe form of OHSS is small, ranging from 0.5 to 5%. Nevertheless, as this is an iatrogenic complication of a non-vital treatment with a potentially fatal outcome, the syndrome remains a seriou...
