Patient's question:
I have had sex with my boyfriend 20 times and have never felt intense pain. On one occasion, on the last day of my period when there was still a little blood, I felt a slight pain. Later, I found some blood, but I wasn't sure if it was from my hymen breaking or just period blood. I want to ask, if it wasn't broken, would I not be pregnant?Doctor's answer:
Here are the translations for the provided text:Except for the methods to determine if a woman is a virgin, there are:
(1) Go to a Class III-A hospital, ask a friend to bring your girlfriend, and have one milliliter of blood drawn 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 or not. 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 besides you who have had sex with her.
The scientific principle behind virginity testing is:
When a woman’s body comes into contact with sperm, the sperm are perceived as foreign invaders by her body. As a result, the immune system produces antibodies to eliminate the sperm. This process kills off lower-quality sperm while allowing higher-quality sperm to fertilize the egg, embodying the principle of survival of the fittest. For a woman, sperm are similar to viruses invading the human body. The immune system recognizes them as foreign and produces corresponding antibodies to combat them. Therefore, different men’s sperm entering the same woman’s body will produce different types of sperm antigens.
This same method can also be used to test whether a married woman has cheated.
