The International Health Organization stipulates that men's sperm will not be less than 20 million per ml. If it is less than 20 million, it will be attributed to young sperm disease, and fertility will have a great impact.It is less than 20 million and between 10 million, called mild and less spermatozoa; less than 10 million, greater than 5 million, is called moderate minor spermatozoa; less than 5 million is called severe minimal spermatozoa; if it is saidYou can only find a few sperm in a high -power vision, or you can see a few sperm after centrifugation, called severe youth.
In recent years, the quality of human sperm has been declining with the environment of the environment, the pollution of estrogen poison and other factors.There are many factors that cause young sperm, inflammation and drugs; alcohol poisoning, excessive smoking, drugs can inhibit sperm production; sperm varicocele, etc. can inhibit sperm production.
(1) Endocrine abnormalities
Men's normal sperm function depends on the normal gland axis function of hypothalamus & mdash; pituitary & mdash; in any link of it will affect the spermatogenic function. Others such as thyroid and adrenal diseases will also affect the reproductive gland function and cause less sperm disease.
(2) Cultivation test
It is reported that there are about 30%to 60%infertility in unilateral ucchievable patients, while bilateral cryptor tests have 50%to 100%infertility, and about 9%of patients with cryptor tests in young sperm disease.In addition to the degeneration of the sperm tubular in the hidden test itself, the decreased testis on the other side may also have different degrees of damage. The reason may be due to the impact of anticin antibodies produced by cryptor test on normal testicles.
(3) Inflammation of the urogenital system
Including orchitis, epididymitis, seminal vesiculitis, prostatitis, urethritis, etc., these patients have the most proportion among young sperm disease.The inflammation of the urogenic tract can directly affect the sperm function of the testicular. It can also cause antibody antibodies in the blood or semen, affect the pH of the semen, and the direct killing effect of the pathogen to the sperm, which can cause sperm reduction.
(4) Excisite veins
The infertility caused by varicose veins accounts for 30%to 40%of male infertility.Due to the increase in testicular temperature and the accumulation of toxins, the testicular sperm function is affected, causing young sperm, and severe can cause no seizure.The symptoms of the iconic veins are not obvious since the beginning of the veins. Those with severe condition can feel the swelling of the scrotum part, protruding like earthworm -like blood vessels.Semen examination can be seen, the number of sperm decreased, poor activity, and increased sperm.
(5) Excessive temperature of the scrotum
The sperm tubes used to make sperm in the testicles are very sensitive to temperature changes. The suitable temperature of this part is 2 to 3 ° C than the body temperature of the human body. Excessive temperature is easy to suppress the survival and maturity of sperm, resulting in a decrease in sperm in semen or activity.Reduce ability.Therefore, male friends should wear less tight pants, take less sauna, avoid electromagnetic radiation and high temperature, and develop good living habits.
