Testis is located in the scrotum, one left and right.The testicles are slightly flat oval, with smooth surfaces, divided into inner, outer sides, front, back edge, upper and lower end.The anterior edge is separated; the posterior edge has vascular, nerves, and lymphatic vessels in and out, and is in contact with the subciplication and the lower paragraph (testicular part).As the testicles grow rapidly with sexual maturity, the testicular of the elderly has shrunk with the decline of sexual functions.
Testes are male reproductive organs.Normal men have two testicles, which are located on the left and right sides of the scrotum.The testicular is oval and gray.Adult testicles are 3.5-4.5 cm long, 2-3 cm wide, 1-2 cm thick, and tested for 10-15 grams on each side.Generally, the left side is about 1 cm lower than the right.Some people have a large testicles, one, one high and one low, and if the difference is not large, it is normal.There are a lot of curved sperm tubes in the testicles, which contains interstitial cells.The sperm tube is a place where sperm is produced. The number of sperm generated by a person in his life is amazing, with 3-4 ml of ejaculation at a time, containing 30-400 million sperm, and less than 10 million.The number can reach more than 1 trillion.The generation of sperm is affected by various factors such as temperature. If the temperature around the testicles is too high or the influence of chemical poisons, the production of sperm will cause obstacles.Intective cells produce androgen are closely related to male second sexual characteristics and physiological functions.
There is a thick layer of fibrous membrane on the surface of the testicles, called white membrane, which is thickened along the white film of the testes, and the testicular septum is formed in the testes.Many connective tissues are issued from the vertical section, and the testicular essence is divided into many testicular leaflets.The testicular leaflet contains the sperm tubes of Panqu, and the epithelium of the fine tube can produce sperm.There are homogeneous cells that secrete male hormones in the connective tissue between small tubes.The fine tube is combined into a straight tube, and the testicular septum is intertwined into a testicular network.12 to 15 testicular output small tubes from the testicles, and the upper part of the testes enter the epididymis.
Testicles are men's "diamonds". It makes sperm and secretes androgen, which can be described as the foundation of its life.In the eyes of most men, the size of the testicles is related to the performance, the larger the better.
In fact, this is one -sided.Men's testicles have a normal range, and men can check themselves.
A study by Huang Zhixian, attending physician of the Department of Urology, Taipei Rongmin General Hospital, pointed out that there is a simple detection method to use the thumb and index finger to do the "OK" gesture.Men can use the circles of two fingers to set the testicles. If it is very loose or cannot be stuffed at all, it means that the testicular size is abnormal. It is best to go to the hospital for examination.
Generally, the testicular volume of Chinese adult men is about 15 & mdash; about 23 ml, and the difference between the sides of the testicles on both sides does not exceed 2 ml.Those who are less than 12 ml, indicate that testicular development is dysplasia or atrophic.If the testicular volume is abnormally increased, it may be a testicular semen cyst or tumor, or it may affect the testicular function.
In addition to the size, the testicular location is also a question that needs to be paid attention to.If the location is too high, the testicular function will be affected in the groin, even in the stomach.At the same time, the normal testicular texture is hard and has a certain elasticity.Hard but not elastic, or too soft, indicating that internal organizations may be damaged.It is recommended that men check their testicles every month in order to find problems early and receive treatment.
