How Many Follicles Is Considered Hyperstimulation

This large, retrospective analysis of individual subject responses from 3 large phase III clinical trials suggests a total of 19 or more follicles ≥11 mm is associated with an increased risk of moderate to severe OHSS.

How many eggs is considered hyperstimulation?

If you have had 20 or more eggs collected and/or very high oestradiol (a hormone measured during your treatment) levels during IVF, your chance of developing OHSS is increased.

How do I know if I have OHSS?

Diagnosis and Tests Physical exam: Checks your weight and measures the size of your waist to look for signs of swelling. Ultrasound: Looks for free fluid in the abdomen and the size of the ovaries. Chest X-ray: Looks for fluid in the chest. Blood test: Measures hormone levels for signs of OHSS.
