What is an "imperforate hymen"?

An imperforate hymen is a condition where the hymen, a thin layer of tissue that partially covers the opening of the vagina, completely blocks the vaginal opening. This condition is present at birth and can lead to symptoms such as abdominal or pelvic pain, difficulty urinating, or difficulty passing menstrual blood due to the blockage. It can also interfere with sexual intercourse, leading to pain or discomfort during attempted penetration. Treatment typically involves a minor surgical procedure called hymenotomy, where a small cut is made in the hymen to create an opening, allowing menstrual blood and other fluids to pass through.
