These three peer-reviewed articles research the pathophysiology of the erectile dysfunction (ED) associated with bicycling. They together report that the high pressures in the perineum while straddling a saddle compress and temporarily occlude penile blood flow. They also hypothesized that the lining vessels of the compressed arteries become damaged, thus leading to potential permanent artery blockage.

However, not all men who ride bicycles will develop erectile dysfunction. One past study suggested that sexual health consequences adversely affect 5% of riders (based on survey data that would therefore include 1,000,000 riding men with ED).
