Overview

The overall incidence of Fournier gangrene annually is 1.6 cases per 100,000 males. The incidence peaked and remained steady after age 50 at 3.3 cases per 100,000 males. Fournier gangrene affects individuals of all ages but more commonly affects individuals older than 50 years of age.. Men are more commonly affected with Fournier gangrene than women, with a male:female ratio of 10:1.. Mortality rate decreases with early aggressive treatment. The mortality rate of Fournier gangrene is between 20% to 80%. Higher mortality rates are found in daibetics, alcoholics and those with colorectal sources of infection.
