How long can semen survive?

Semen is a substance secreted by male genitals, and it is also the main way of our inheritance. After being secreted, semen can generally survive for a few days. It can survive in the female vagina for three days. If it does not meet the egg within three days, it will die automatically and be discharged from the body. If we want to successfully conceive, we need to improve the quality of sperm and egg and make the sperm more active.

Sperm is not good at surviving in this world, and its life span is reduced by various factors. Even if it tries its best to survive the long and arduous journey inside the female body, it still has only a one in 200 million chance of fertilizing the egg (assuming all sperm in the same batch can make it to the end).

In the womb

Sperm can survive for up to 74 days in a man's own testicles, but the best place for sperm to survive is in the female body. More precisely, sperm can survive for up to two days on average in a woman's uterus (although thousands of them die on the way there). In fact, during ovulation, when a woman's vagina is moist and warm, sperm can survive for up to five days.

"This usually happens close to ovulation when there is enough cervical mucus in the vagina to nourish the sperm, but, very rarely, if the sperm are able to get into the right place, such as the fallopian tubes, they can survive for up to seven days." Unfortunately, this is the longest sperm can survive in your ejaculation.

In the human mouth

Theoretically, it is entirely possible for sperm to survive in the mouth (admittedly, the possibility is not high) because the human mouth is an ideal environment for sperm survival, it is warm and moist.

The science behind this is that the temperature in the mouth is warmer than outside the body, and the mouth is a mucous membrane structure with gums, crevices, and depressions. In theory, it is 100% reasonable that sperm that enters the human mouth through some well-known means can survive for a day or even two days. "

On the skin

, sperm can only survive for a few minutes outside the body. But how long it survives can vary dramatically depending on the surface or environment it's in. Semen can survive for 20 minutes near the vagina, where it's also likely to be warm and moist, which is why birth control via ejaculation outside the body is only 80% successful. The same goes for other moist skin surfaces, like a sweaty breast or a sticky palm.
