Patient's question:
I have had sex with my boyfriend 20 times and have never felt intense pain. Once, on the last day of my period when there was still a little blood, I felt a bit of pain. Later, I found some blood but wasn't sure if it was from my hymen breaking or just menstrual blood. I want to ask, if it wasn't broken, would I not be able to get pregnant?Thank you!
Doctor's answer:
Methods for identifying a woman's virginity, besides the hymen, include:(1) Go to a Class III-A hospital, ask a friend to accompany you and your girlfriend, and draw one milliliter of blood from your wife for a sperm antigen test. If you haven’t had sex with your wife, the presence of sperm antigens would indicate that she is no longer a virgin, regardless of whether her hymen is intact. If you have had sex with your wife, the presence of two or more types of sperm antigens would suggest that there have been other men involved, either in the past or currently.
The scientific principle behind this method is that when a woman’s body comes into contact with sperm, it recognizes them as foreign invaders. As a result, the immune system produces antibodies to eliminate the sperm. Poor-quality sperm are destroyed, while high-quality sperm are allowed to fertilize the egg, embodying the principle of survival of the fittest. For a woman, sperm are like viruses invading the body. The immune system perceives them as foreign and produces corresponding antibodies to combat them. Therefore, different men’s sperm entering the same woman’s body can produce varying types of sperm antigens.
This same method can also be used to test whether a married woman has been unfaithful.
