WHAT IS OHSS?

The medications (gonadotropins) used to stimulate your ovaries during In-Vitro Fertilization (IVF) or associated procedures for fertility treatment are designed to ensure that a reasonable number of eggs are obtained to maximize your chances of pregnancy.

Ovarian Hyperstimulation Syndrome (OHSS) happens when too many ovarian follicles have developed in response to the usual dosage of medication. It is a result of the hormones produced by the ovaries in response to the drugs given.
OHSS is usually mild and causes no more than a slight lower abdominal discomfort in most cases.

Although uncommon, it warrants medical attention as it can be potentially life threatening if left untreated in severe cases.
When detected early and managed appropriately, the condition can be alleviated.

OCCURRENCE OF OHSS

Some 6 to 8 percent of patients undergoing IVF treatment will experience mild forms of OHSS. The severe form will affect less than one percent of patients.
