What causes a cold scrotum?

Men are usually worried when they find that their scrotum feels cold. In fact, the scrotum is one or two degrees lower than normal temperature. Keeping it at such a low temperature is more conducive to the survival of sperm and ensures the quality of sperm.

1. A cold scrotum is a normal phenomenon. Under normal circumstances, a man's testicular temperature is about 1-2 degrees lower than normal body temperature. The testicular temperature must be kept cold so that sperm can survive normally and sperm motility can reach normal standards.

2. There are many wrinkles on the scrotum, which are used to regulate the temperature of the testicles. When the temperature of the crotum is too high, the scrotum will sag, and the wrinkles will open to dissipate heat. When the temperature of the crotum is low, the scrotum will shrink to ensure the temperature of the testicles. Therefore, when you take a hot bath, you will see that the scrotum sags severely and the testicles also sag. When you swim, the water temperature is relatively low, and you will see that the scrotum shrinks tightly together, and it feels like you can't even see the testicles.

3. Therefore: It is recommended that boys should not wear tight underwear and outer pants to give the scrotum a space to dissipate heat, thereby ensuring the activity of sperm. In recent years, many boys cannot get pregnant normally after marriage. Routine semen examination will find that the activity of sperm is lower than normal indicators, leading to infertility, which is directly related to wearing tight underwear and outer pants.
