Patient's question:
NoDoctor's answer:
If you feel there is a problem, check the hormone secretion. Generally, virgins do not have such conditions. If it looks very dark, from a medical perspective, you should go to the hospital to check the endocrine condition, as it is likely due to excessive hormone secretion or irregular menstruation. It could also be caused by uterine coldness. If the test results are normal, then it should be congenital.
