Sexually transmitted infections are also referred to as sexually transmitted diseases (STDs) that are commonly spread by sexual activity, especially vaginal intercourse, oral sex, and anal sex. STIs seldom cause symptoms initially, which results in a greater risk of passing the disease on to others. Symptoms and signs of STIs may include vaginal discharge, pelvic pain, ulcers on or around the genitals, and penile discharge. Transmission of STIs can be witnessed to an infant before or during childbirth, which may result in poor outcomes for the infant. Some STIs can cause infertility. Safe sex practices, such as use of condoms, having a fewer number of sexual partners, and being in a relationship in which each person only has sex with each other also decrease the risk of STIs. Circumcision in adult males may be effective to prevent some infections.
