Abstract
ABSTRACTART 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. The trigger for initiation of OHSS appears to be human chorionic gonadotropin (hCG). In conception cycles symptoms may persist longer due to endogenous hCG stimulus. Vascular endothelial growth factor (VEGF), a member of the transforming growth factor superfamily, has emerged as one of the factors most likely involved in the pathophysiology of OHSS. There are various risk factors which increases the risk of developing OHSS during the stimulation like PCOS, low body weight, previous history of OHSS, etc. Primary and secondary preventive measures are been tried to reduce the risk of developing OHSS. GnRHa trigger in patients at risk revealed that incidence OHSS was reduced or totally eliminated. Use of antagonist cycle with an agonist trigger and elective vitrification of all embryos allows us to aim for an ‘OHSS Free’ clinic today.How to cite this articleMahajan N.
