Ovarian hyperstimulation syndrome

Published: 01/11/2007

Ovarian hyperstimulation syndrome (OHSS) is a potentially serious complication of fertility treatment, particularly of in vitro fertilisation (IVF) treatment.

This information leaflet provides advice to women taking fertility drugs to stimualte ovary production. It covers:

  • Symptoms of OHSS
  • Causes of OHSS
  • Who is at risk of OHSS
  • How long OHSS lasts for
  • What you should do if you have mild OHSS
  • When you should call for medical help
  • What happens if you need to stay in hospital
  • Treatments for OHSS
  • Other sources of useful information

This patient information leaflet is based on the RCOG clinical guideline Management of Ovarian Hyperstimulation Syndrome, which contains a full list of the sources of evidence used to produce this guidance.

In line with the College process of reviewing all guidance every three years, this information is currently under review. The information in this version is still valid.
