To be a healthy, masculine man, it is important to understand and protect your testicles. However, in real life, many people know little about the testicles. Let us take a look at it below.
The main physiological function of the testis
The physiological role of testes in the human body is mainly the production of sperm and androgens. During the formation of sperm, a suitable and constant environment is required. Among them, temperature is an important condition in the formation of sperm. Shortly after birth, the testicles descend from the abdominal cavity into the scrotum, and the scrotal relaxation and contraction has the effect of regulating temperature. When the outside temperature rises, the scrotum relaxes and expands the heat dissipation area; conversely, when the outside temperature decreases, the scrotum shrinks to keep warm. Through this adjustment, the temperature inside the scrotum is kept optimal, that is, 1.5 to 2.0 ° C lower than the abdominal cavity. In addition, diet, radiation, hormones, drugs, diseases, etc., can lead to abnormal or pause in the spermatogenesis process. In normal times, the functional activity of normal testes is regulated by neuro-humoral factors. The testicles have self-protection. When the person is in a state of nervousness, the testicles will be lifted up quickly and wrapped tightly by the scrotum to avoid danger.
Several male hormones can be extracted from human testes, usually called androgens. The main effects of androgens are as follows:
1. Stimulate the growth, development and maturation of male sexual organs (epididy, prostate, penis) and maintain their normal life function.
2. Stimulate the appearance of sexual characteristics, and maintain their normal state, such as thick bones, muscle development, low voice, thick throat, prominent beard and so on.
3. Promote sperm production and extend its life and childbearing period.
4. It has important metabolism, can promote protein synthesis, keep nitrogen, potassium, calcium and phosphorus in the body, produce positive balance of nitrogen, increase basal metabolic rate, promote muscle development and bone growth. Androgen also stimulates bone marrow hematopoiesis and increases red blood cells and hemoglobin.
Common testicular disease
The cryptorchidism testicular at the time of embryogenesis, on the sides of the lumbar retroperitoneal spine, gradually decreased with the development of the embryo, the testicles can stay in the abdominal cavity, the inguinal canal, the upper part of the scrotum, etc., without falling to the scrotum They are collectively referred to as cryptorchidism. Most cryptorchidism patients, because the testicles stay in an abnormal position for a long time, affect the development of the trematode tube, due to the high temperature of the abnormal parts, the tempering of the scrotum is lost, thus affecting the production and vitality of the sperm. In particular, patients with bilateral cryptorchidism, if not treated properly, will affect fertility.
The hydrocele of the testis has the ability to secrete the absorption of the slurry, such as excessive secretion or malabsorption, which can increase the fluid and fill the sheath cavity to form a hydrocele. It can be treated by traditional Chinese medicine or surgery.
Testicular tumors and testicular tumors are mostly malignant and benign. The cause is not very clear, and timely treatment of cryptorchidism is important for the prevention of testicular tumors. At present, the disease is mainly based on surgical resection and radiation therapy.
In addition, there are diseases such as epididymal tuberculosis and varicocele, which require timely treatment.
Do not wear tight pants, it is best not to wear tight underwear and jeans, especially in the summer, should wear loose pants, so that the air circulation, to avoid excessive temperature, affecting the normal function of sperm.
To prevent trauma, be careful not to expose the testicles to trauma, especially kick injuries.
Smoking cessation, alcoholism, smoking, alcoholism have adverse effects on sperm production and vitality, can cause infertility or fetal malformation, so you should quit smoking and limit alcohol.
In addition, malnutrition, especially the lack of vitamin E, vitamin A, etc., as well as obesity, etc. will affect the production of sperm, so we must pay attention to adjust the diet and strengthen prevention. Chronic wasting diseases such as tuberculosis, diabetes, etc. can affect the production of healthy sperm. Local lesions such as tuberculosis, syphilis, etc. can damage testicular tissue. Mumps and flu can induce orchitis, causing both testicles to shrink and not produce sperm. Suffering from chronic prostatitis can affect semen liquefaction. In short, suffering from the above diseases, should strengthen prevention and treatment, so as not to lead to normal testicular dysfunction, affecting fertility.
