Often the jeans are worn in male sterility
The boy should not wear too tight jeans, this correlates with living environment that development, structure and external genitalia of male genitals need.
Wrapping up the testis in the male sexual organ scrotum, the testis is the place for producing the sperm. The scrotum will be relaxed in hot summer; When it is cold, the scrotum will be tightened into a wrinkled small group, abut body tightly. It means, the scrotum needs suitable temperature, it will vary with temperature and carry on self-regulation.


Careful to wear the close-fitting jeans


There is not lower fat of skin that have abundant sweat gland, contribute to dispelling the heat. When the external temperature is low, stimulate the smooth muscle of the membrane of meat and carry the skin of testis to shrink, make the position of testis rise, the skin of scrotum is tightened into dense fold, and the retraction is to the perineum department, prevent dispelling the heat, contribute to keeping warm.


On the contrary, when the external temperature is raised, smooth muscle and carrying the skin of testis relaxedly, the testis drops, leave the body, the skin of scrotum is lax, increase the heat-dissipating area, help the part to dispel the heat.


In addition, the artery in the spermatic cord is twined on the intravenous clump that Cheng Shu runs side by side, the blood is in two sets of blood-vascular systems, but flow backward, form a adverse current exchange system only through the thin blood vessel wall, intravenous blood take away the intersection of arterial blood and heat to come from abdominal cavity constantly, blood of testicular artery warm to 5.2 degrees centigrade lower than belly aorta finally. The scrotum adjusts the temperature in scrotum and testis through these kinds of mechanisms.


Must not look down upon the ability of scrotum, it multiply descendants to be too important to mankind. Because the temperature has influence greatly, low about 2 in specific humidity organism in the scrotum on that the testis grows the precise course, it is the optimum temperature of growing precise function. The temperature is too high, growing the precise course will present the obstacle, even dead stop, the secretion of ketone of testis will be reduced at the same time. Any above-metioned link is cranky will because influence the regulation of the scrotum temperature and cause sterility.


The close-fitting trousers are worn should pay attention to


Some young man, like, wear close-fitting trousers, especially good chemical fibre " wrap the intersection of shelf and trousers up " Wrapping up the scrotum, let the scrotum be in airtight state, the air does not circulate, makes the bacterium breed, cause inflammation of the reproduction one; Hinder the skin of scrotum from dispelling the heat and lowering the temperature at the same time, restrain the blood from circulating, hinder the intravenous reflux of spermatic cord, production and nutrition to the sperm are very unfavorable. If things go on like this, easy to cause the sterile bad consequence in the future.


Although close-fitting trousers are goodlooking, it is not scientific from the viewpoint of healthy reproduction. The boy should choose the trousers of slightly great, ventilative good, cotton quality while buying the jeans.
