Note: The jeans can lead to infertility

wrapped inside the scrotum testicle, testis where sperm is produced.In the hot summer will relax the scrotum; When the weather is cold, the scrotum will tighten wrinkled into a small group, firmly attached against the body.This shows that the temperature of the scrotum requires appropriate, it will change with temperature self-regulation.

Careful to wear tight jeans

No subcutaneous fat and is rich in sweat glands to help heat dissipation.When the outside temperature is low, the stimulation of smooth muscle and the dartos cremaster muscle contraction, the increase in testicular position, scrotal skin to squeeze into the thick folds and retraction from the perineum to prevent the heat and help keep warm.

In contrast, when the outside temperature, smooth muscle, and cremaster muscle relaxation, testicular descent, left the body, the scrotum skin loose, increasing the cooling area, is conducive to local cooling.

In addition, the arteries of the spermatic cord wrapped in bundles parallel veins in the plexus, the blood vessels in the two systems, separated only by a thin vessel walls and reverse flow, forming a counter-current exchange system, blood continuously arterial blood from the abdominal cavity to the heat away, the results of testicular arterial blood temperature by 5.2 degrees Celsius lower than the abdominal aorta.Scrotum is through these types of mechanisms to regulate the temperature inside the scrotum and testicles.

this ability, it is too important for the future generations of human reproduction.

Because the temperature on the spermatogenesis process has great influence on the body scrotal temperature lower than 2 degrees Celsius is the optimum temperature of spermatogenesis.Temperature is too high, there will be obstacles to the process of spermatogenesis, or even completely stopped, while testosterone will also decrease.The failure of any one link in the chain will affect the scrotum temperature by regulating and cause infertility.

Wearing tights Note

Some young men like to wear tight pants, especially the poor ventilation, poor thermal profile of chemical fiber trousers pocket wrapped the scrotum, the scrotum in a closed state so that air does not circulate, so that the growth of bacteria, causing inflammation of the reproductive tract; also hinder the scrotal skin thermal cooling, limiting blood circulation, prevent spermatic vein reflux, on sperm production and nutrition at a disadvantage.Over time, likely to cause adverse consequences for future infertility.

tights look good, but from the perspective of reproductive health is not scientific.When buying jeans boys, should be chosen slightly larger, good ventilation, quality cotton pants is appropriate.
