What causes bleeding during sexual intercourse?

Bleeding during sexual intercourse is not a normal phenomenon and should be taken seriously, as it may be caused by various factors: 1. Mucosal injury: It could be a result of minor damage to the vaginal or uterine mucosa during sexual activity. Usually, the bleeding is minimal and can heal on its own. 2. Infection and inflammation: Conditions such as vaginitis or cervicitis may cause mucosal congestion and damage, leading to bleeding. 3. Sexually transmitted diseases: STDs such as genital warts or gonorrhea can also cause bleeding after sexual intercourse. 4. Endometriosis: This refers to the growth of endometrial cells outside the uterus, which may cause pain during intercourse and bleeding. 5. Tumors: Although relatively rare, cervical cancer or other gynecological tumors may also lead to postcoital bleeding. It is recommended to seek medical examination promptly to determine the cause and receive appropriate treatment.
