How long can sperm survive outside the body? Sperm can survive no more than 24 hours outside the body. Authoritative experts suggest: The survival time of sperm has certain requirements for the environment. Generally, it will die in less than 2 hours. Once sperm is ejaculated, there is no environment for survival. It can survive for up to 24 hours in the water environment outside the body and 3-5 minutes in the dry environment outside the body. If the temperature is reduced, the sperm survival time can reach several weeks; if it is refrigerated with liquid nitrogen, the sperm survival time can be longer, and it can even be stored for a long time.

The survival time of male sperm in the body 1. The survival time of sperm in the female vagina The survival time of male sperm in the female vagina is 2 hours after sexual intercourse, and 90% of them die. In the vagina of pregnant women, the higher the acidity, the faster the sperm die.

2. Survival time in the cervix: The survival time of male sperm in the cervix is ​​within 36 hours after sexual intercourse, but sometimes there are exceptions, and some sperm survival time is very long.

3. Survival time in the bilateral fallopian tubes In the bilateral fallopian tubes, there will be active sperm 14 hours after sexual intercourse, and sometimes there will still be active sperm after 35 days. Generally, those that survive for 14 days are more active, and some enter the abdomen. Those that move slowly are pushed back into the uterine cavity by the microvilli.

Sperm survival temperature How much does it cost? Semen is composed of sperm and seminal plasma. The sperm density of an adult male is about 2-6 ml each time, of which more than 95% is seminal plasma. For the sperm to survive, the temperature requirement is more critical. The sperm survival temperature is controlled between 34℃ and 36℃.

Generally speaking, in the case of AA, sperm will directly enter the female body through the vagina. If the female does not have a fever, the temperature belongs to the normal temperature of the human body, so the sperm can survive in the body for a period of time. Note: Sperm is suitable for temperature control at 34℃～36℃. It is best to avoid areas that are not suitable for the growth and development of sperm, such as taking a sauna, where the indoor temperature reaches 70℃～80℃. Such a temperature is very easy to destroy the growth and development environment of sperm, or cause too much "dead sperm" and lead to infertility, so it is better to avoid it.
