The bleeding can be from the uterus, cervix, vagina and other tissue or organs located near the vagina.[4] Postcoital bleeding can be one of the first indications of cervical cancer.[5][6] There are other reasons why vaginal bleeding may occur after intercourse. Some people will bleed after intercourse for the first time but others will not. The hymen may bleed if it is stretched since it is thin tissue. Other activities may have an effect on the vagina such as sports and tampon use.[7] Postcoital bleeding may stop without treatment.[8] In some instances, postcoital bleeding may resemble menstrual irregularities.[9] Postcoital bleeding may occur throughout pregnancy. The presence of cervical polyps may result in postcoital bleeding during pregnancy because the tissue of the polyps is more easily damaged.[10] Postcoital bleeding can be due to trauma after consensual and non-consensual sexual intercourse.[11][4]
A diagnosis to determine the cause will include obtaining a medical history and assessing the symptoms. Treatment is not always necessary.[12]
