how long does sperm live in testicles
It is heat sensitive and cannot survive in high temperature. In the man's testicles, the semen or seminal fluid provides a favorable environment. Here, the seminal fluid allows the sperm to be motile and in constant temperature. Inside the body, sperm lives for up to 74 days. The main reason why male's testicles are hanging further away from the man's body is that to protect the sperm from the heat of the body. Sperm may also die due to the person's negative lifestyle. Alcoholism, smoking, drugs and others can affect sperm survival rate.
