Trichomoniasis is a common sexually transmitted infection that can be extremely unpleasant and even dangerous. Here are the worst types of trichomoniasis: Trichomoniasis vaginalis is the most common form of the infection and is caused by a parasite that lives in the vagina. It most commonly affects women between the ages of 18 and 45, but it can also affect men and children. Symptoms may include itching, discharge, pain during sex, and fever. If left untreated, trichomoniasis can lead to pelvic inflammatory disease (PID), which can cause serious complications including infertility. Trichomoniasis urogenitalis is a more severe form of the infection caused by a parasite that lives in the male reproductive system.
