Sexually transmitted diseases are a special type of infections that spread by sexual relations by vaginal, anal or oral sex. Mostly these infections do not show symptoms in early stage of the disease and spread from one to another silently. The major symptoms of these infections include abnormal vaginal or penile discharge, ulcers on or around the genitals, and chronic pelvic pain. Some infections are too dangerous that they may cause failure to get pregnant, can pass to new baby or even can cause death. Some sexually transmitted diseases are listed below

To prevent these sexually transmitted diseases unprotected intercourse with any partner should be avoided.
