Experts remind that men should not wear too tight jeans, which is related to the development and structure of male reproductive organs and the living environment required by external genitals.
Men's sex organs scrotum is wrapped in testicles, and testicles are sperm.In the hot summer scrotum will relax; when the weather is cold, the scrotum will tighten into a wrinkled small group, clinging to 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.
