Patient's question:
I have had sex with my boyfriend 20 times and have never felt severe pain. Once, 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 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:
Here are the translations of the provided text into English, with the specified requirements followed: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, bring your girlfriend along, draw one milliliter of blood from your wife, and conduct a sperm antigen test. If you haven’t had sex with your wife, the presence of sperm antigens would indicate that your wife is no longer a virgin, regardless of whether she still has her hymen. 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.
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 the female body. As a result, the body produces certain antibodies to eliminate the sperm. Therefore, lower-quality sperm are destroyed, while higher-quality sperm are unaffected and can combine with the egg. This is the principle of survival of the fittest.
Sperm are like viruses to a woman—her immune system recognizes them as foreign invaders and produces corresponding antibodies to combat them. Thus, when sperm from different men enter the same woman’s body, the types of sperm antigens produced vary.
The same method can also be used to test whether a married woman has cheated.
