Does sperm hate heat?

The male reproductive system has its own set of circulation rules. Many men will find that their scrotum will loosen up when it is hot and will gather together when it is cold, so this is a very strange phenomenon. In fact, the reproductive system is also very afraid of heat, and if you stay in a hot and humid environment for a long time, the quality and survival rate of sperm will be greatly reduced. So be sure not to let your body get cold, and choose loose pants when wearing them.

Mr. Sperm: How afraid of heat are you?

1. High temperature affects sperm survival

Sperm must be kept at a temperature 3-5℃ lower than normal body temperature, that is, generally speaking, the most suitable temperature for male testicles is between 34℃-35.5℃, in order to produce a large number of healthy sperm. If the temperature of the testicles reaches 36℃ or higher, the sperm will definitely suffer from heat stroke, thus affecting the quality of sperm and even causing male infertility.

Experts remind that long-term work in a high-temperature environment will definitely affect the survival rate of sperm. Therefore, men in some professions such as chefs and drivers need to pay more attention to heat dissipation in the summer to avoid the testicles being in a high temperature state for a long time.

2. The scrotum regulates the temperature of sperm

The testicles in the scrotum are where sperm is produced, and the epididymis is where sperm is stored. Under normal circumstances, the scrotum acts like a thermostat. When the temperature drops, the scrotal skin shrinks and thickens, bringing the testicles closer to the body and raising the temperature of the environment around the testicles.

When the temperature rises, the scrotal skin relaxes and becomes thinner, the testicles sag and move away from the body, the heat dissipation function is enhanced, the temperature of the environment around the testicles is reduced, and the temperature inside the scrotum is basically kept stable at 32 degrees Celsius to 33 degrees Celsius.

3. Mr. Sperm has heat stroke, the consequences are very serious

Under normal circumstances, the testicles produce about hundreds of millions of sperm every day, and the testicles are extremely sensitive to temperature. Once the temperature around the testicles rises abnormally for some reason, it may cause testicular spermatogenesis dysfunction or testicular spermatogenic epithelial cells to degenerate, resulting in semen abnormalities.

High temperatures harm sperm, which is mainly manifested by reduced sperm density in semen, decreased sperm motility, increased sperm abnormalities, and even azoospermia in severe cases. Due to the above changes in semen quality, the fertilization ability of semen is reduced, which often leads to infertility.
