OHSS: 

OHSS is a rare complication of the controlled ovarian hyperstimulation needed for IVF. Your ovaries will be purposely hyperstimulated in order maximize egg production, however on rare occasions the ovaries over-respond to the medications. Rarely, hospitalization may be required for intravenous fluids and close monitoring of your vital signs and symptoms. Unfortunately, this complication is worsened or prolonged by the pregnancy itself. 

Cancer Risk and IVF:

There have been many articles in the medical literature evaluating the association between the use of fertility drugs and ovarian cancer. These drugs have been used for over 30 years in the treatment of infertility. It is important to know that most of the articles published have shown no increase in the risk of ovarian cancer with the use of these drugs.

A thorough analysis of all studies has been conducted by the American College of Obstetrics and Gynecology and the American Society For Reproductive Medicine. Further studies are ongoing and will help clarify any possible association. Another important point for any patient with infertility to know is that having a baby reduces your risk for ovarian cancer by over 50%.
