Patient's question:
Medical Description: My girlfriend helped me with her hands because she was in her fertile period, and I ejaculated outside of her body. After that, she used toilet paper to wipe her hands but did not wash them. About 5 minutes later, my girlfriend said she touched her vagina with her hands. I want to ask: If the sperm on her fingers was not completely wiped off, would touching her vagina with her hands cause the sperm to swim into her body and lead to pregnancy? Since she was in her fertile period and the sperm had only been outside of her body for about 5 minutes, I don't know if they have died.History of Treatment and Effect: No treatment history.
Help Needed: Please have a doctor answer this.
Doctor's answer:
The vaginal acidic secretion is normally pH 3.5-4. Although theoretically, only one viable sperm is needed for fertilization, in the acidic environment of the vagina, most sperm die shortly after entering. Only with the buffering effect of a certain amount of semen can the survival time of a small number of highly resilient sperm be extended, giving them a chance to enter the uterus and fertilize. Without the sacrifice of a large number of sperm and without the buffering effect of a sufficient amount of semen to improve the acidic environment of the vagina, a single sperm or a very small number of sperm would not be able to survive and fertilize in the acidic environment. Generally, the survival time of sperm in the vagina is as follows: 2 hours after intercourse, 90% die; 36 hours later, even the dead ones are no longer visible. In pregnant women, the stronger the acidity, the faster the sperm die.
