Patient's question:
I recently had sex with my wife while using a condom, but I'm also worried that sometimes sperm might be left on the hair, which could cause my wife to get pregnant. I don't know how long sperm can survive outside the human body. We don't plan to have children for now. I haven't really researched this topic much.What kind of help do I need: How long can sperm survive outside the body?
Doctor's answer:
After normal semen is emitted, it becomes gelatinous under the action of seminal vesicle coagulase and turns into a liquid after 15 to 30 minutes under the action of prostatic liquefying enzyme. This is called semen liquefaction. Therefore, the survival time of sperm outside the body is very short, generally around 15 to 30 minutes.After normal semen is emitted, it becomes gelatinous under the action of seminal vesicle coagulase and turns into a liquid after 15 to 30 minutes under the action of prostatic liquefying enzyme.
