Men's sex organs scrotum is wrapped in testicles, and testicles are sperm.In the hot summer scrotum, it will relax; when the weather is cold, the scrotum will tighten into a wrinkled small group, leaning against the body tightly.This shows that the scrotum needs to be appropriate temperature, which will self -regulate with the temperature.
Character wearing tight jeans
No subcutaneous fat and rich sweat glands can help heat dissipation.When the external temperature is low, stimulate the smooth muscle and testeus muscle contraction of the meat membrane, so that the testicular location is increased. The scrotum skin is tightened into dense wrinkles and retracted to the perineum to prevent heat dissipation and help heat thermal insulation.
On the contrary, when the temperature is rising, the smooth muscle and the testis of the testis are relaxed, the testicles decrease, and the testicles are left. The scrotal skin is relaxed and increased the heat dissipation area, which is conducive to local heat dissipation.
In addition, the arteries in the sperm cable are wrapped on the intravenous veins in parallel, and the blood is in the two sets of blood vessel systems.The internal arterial blood heat was taken away, and the blood temperature of the testicular arteries was 5.2 degrees Celsius lower than that of the abdominal aortic.Scrotum is to adjust the temperature in the scrotum and testicles through these mechanisms.
Don't underestimate the ability of the scrotum, it is too important for humans to reproduce descendants.
Because the temperature has a great impact on the process of sperm of testicular, the temperature in the scrotum is about 2 degrees Celsius lower than the body, which is the optimal temperature for the effect of sperm.If the temperature is too high, there will be obstacles, or even completely stopped, and the secretion of testosterone will be reduced.Any failure of the above links will cause infertility due to the adjustment of the temperature of the scrotum.
Pay attention to tight pants
Some young men, who like to wear tight pants, especially the chemical fiber "pants" with poor breathability and poor heat dissipation, wrap the scrotum in a closed state, the air does not circulate, causes bacteriaIt also hinders the heat dissipation of scrotal skin, restricting blood circulation, and hindering the return of sperm veins, which is not good for the generation and nutrition of sperm.In the long run, it is easy to cause bad consequences of infertility in the future.
Although tight pants look good, it is unscientific from the perspective of reproductive health.When boys buy jeans, they should choose pants with slightly larger, breathable, cotton -quality pants.
