We know that testicles are the important organs of men and men's gonads. The testicles grow in the scrotum, one left and right. After adulthood, each testicles are about 4 & mdash; 5 cm long, 3 cm wide, about 2.5 cm thick, volume volume, volumeIt is 20 & mdash; 30 ml. The testicular interior is divided into 200 & mdash; 300 testicular lobular leaves have three to four fine tubes in each testicles, which are a place for sperm.The testicular network is issued by Gaowang.com 10 & mdash; 15 testicular output small tubes, wearing testicles, and finally a total testicular output small tube and move towards epididymia.
There are two functions of the testicles. One is to produce sperm and make men have fertility. The other is to secrete androgen. Through blood circulation, it acts on the south, so that men can produce sexual desires, appear and maintain the second sexual characteristics of men, but because of becauseThere are many factors such as genetic diseases and nutrition. The testicles varies from person to person. Of course, some are larger, and some are smaller, but as long as they are within the normal range, it is generally slightly larger.The height cannot be judged with the size of the testicles. It is stronger to have a stronger sexual function, and the sexual function is weak. It is not just that.But there is a bottom line that if the testicular volume is less than 10 ml, it indicates that the testicular development is poor or atrophic.这时候受影响较大的当然在生精这块影响就很大了，一般这种情况，小于10毫升这种睾丸，往往精液中找不到精子，先天性无精子症，或者精子减少，或者Sperm activity rate is extremely low.
If the testicles on both sides are less than 6 ml, the interstitial cells that secrete androgen secreted in the testicles will also be affected. At this time, not only the sperm is affected, but the interstitial cells that secrete androgen may also be affected, which will affect sexual function.
The cause of testicular dysfunction is mainly in the following situations
The first is endocrine abnormalities. If endocrine is abnormal, such as hypothyroidism with gonadotropin decreased gland dysfunction, as well as pituitary micromanoma, etc., it affects the development of gonads, causing this testicular dysplane.
The second case is genetic factors, that is, chromosomal abnormalities. For example, the Clan syndrome, which is primary small testosckles or essence of small tubes.
The third is anatomical factors. Individual cases are caused by blood supply disorders during embryo, or testicular development caused by sperm coffee during small testicles, which is caused by anatomical factors.
The fourth type is the infection factors. The most powerful is the viral orchitis caused by mumps caused by childhood, which can cause testicular dysfunction.Pay attention to men's health from hours of grabbing, do not cast major diseases, sometimes irreversible.
The fifth aspect is trauma or surgical trauma. Some people have a good time when they are young and youthful development.Testis development is dysplasia or atrophy.
