What is the cause of vaginal bleeding after intercourse?

Patient's question:

After menstruation, sexual intercourse causes bleeding

Doctor's answer:

In your case, it may be caused by cervical erosion. You need to go to the hospital for examinations such as colposcopy and vaginal ultrasound. You also need to undergo treatments like microwave therapy or loop electrosurgical excision procedure (LEEP). After the surgery, intravenous drip of a large amount of antibiotics is required for treatment. You should avoid sexual activity for one month after the surgery. Pay attention to local hygiene and prevent cross-infection.
