Sperm survival time needs to be analyzed depending on the environment in which the sperm is stored. If the sperm is stored in the male testicles, it can survive for a long time, usually 10-15 days. They are gradually replaced by new sperm. If the sperm is outside the body, it can usually survive for an hour or so, and the higher the temperature, the shorter the sperm survival time. If the sperm has entered the woman’s body, it can survive in the woman’s uterus for about a week, within which time conception is accomplished. At the same time, the physical quality of the male also determines the sperm survival time, the stronger the physical quality of the person, the higher the sperm survival rate, the longer the survival time, in the same temperature and humidity environment, to maintain the number of active sperm will be more. It is recommended that men can exercise moderately in their daily life, which can improve the quality of sperm.
