Ovarian hyperstimulation syndrome

The Royal College of Obstetricians and Gynaecologists defines ovarian hyperstimulation syndrome (OHSS) as a “systemic disease resulting from vasoactive products released by hyperstimulated ovaries”. It is usually the result of gonadotrophin stimulation for in vitro fertilisation (IVF), with moderate and severe cases affecting about 3–8% of cycles. At the heart of OHSS is an increase in vascular permeability causing the movement of fluid out of the intravascular space, with resultant accumulation of fluid in the third space and intravascular depletion.
