The size of the testicles is related to age. From newborn babies to children under 12 years old, the testicles are in a relatively dormant period with a volume of about 1-4 ml. Boys enter puberty after the age of 12, and their testicles increase rapidly. The testicle volume of adult males is 16-25 ml, with an average of 19.8 ml. After the age of 60, men enter a stage of sexual decline and the size of their testicles gradually decreases. After the age of 70, the testicular volume can shrink to less than 16 ml. If the testicular volume of an adult is less than 10 ml, it is considered microtestis, which may lead to sexual dysfunction and male infertility. If the testicles are too small, the spermatogenesis function of the testicles may be impaired, resulting in a small number of sperm or even no sperm, and most of them will lose their fertility function. Testicle size: Examination shows that the plasma testosterone level is very low, the male secondary sexual characteristics are underdeveloped, the beard, pubic hair and axillary hair are sparse, the voice is low and thin, and in severe cases, feminine behavior may occur. Most patients have low libido and sexual dysfunction. The diseases that cause microorchia mainly include Klinefelter's syndrome, congenital adrenal hyperplasia and some hereditary diseases. Testicular abnormalities are mostly caused by diseases such as testicular tumors, epididymal tuberculosis, and testicular hydrocele. If these diseases are not treated in time, they will affect fertility or cause poor quality of sperm and semen, thus leading to infertility. Further reading: How can men prevent infertility? 1. Avoid malnutrition and overnutrition: Both malnutrition and overnutrition will affect male fertility. 2. Do not eat foods that affect fertility: cottonpol in cottonseed oil damages the spermatogenesis function of the testicles; food additives, colorants, preservatives, etc. affect the spermatogenesis function of the testicles; large amounts of pesticide residues in agricultural and sideline products seriously endanger human health and damage the spermatogenesis function of the testicles; hormone-regulating pollutants and estrogen analogs affect sexual and reproductive functions, such as pesticides and plastic packaging. 3. Avoid contact with substances that damage reproductive function: automobile exhaust, paint, cigarette smoke, coatings, gas, and heavy metals such as lead and cadmium. 4. Quit smoking and drinking: Tobacco contains more than 1,200 harmful substances, among which nicotine is the most harmful. Alcohol also greatly damages the spermatogenesis function of the testicles and is a killer of male fertility. 5. Prevent testicular trauma: Testicular trauma can cause serious immune damage. 6. Avoid ionizing radiation and non-ionizing radiation: Testicular tissue is very sensitive to ionizing radiation, such as: X-ray irradiation, marble and other materials; electromagnetic waves, microwaves, ultraviolet rays, etc.; tight underwear, hot baths, saunas, high-temperature work, etc. |
