Risk factors
Sometimes, OHSS happens in women with no risk factors at all. But factors that are known to increase your risk of OHSS include:
- Polycystic ovary syndrome — a common reproductive disorder that causes irregular menstrual periods, excess hair growth and unusual appearance of the ovaries on ultrasound examination
- Large number of follicles
- Age under 35
- Low body weight
- High or steeply increasing level of estradiol (estrogen) before an HCG trigger shot
- Previous episodes of OHSS
