Under normal circumstances, 1 ml of human 1 ml of semen contains 20 million to 25 million sperm, 1 to 6 ml of ejaculation is 2 to 6 ml, and ejaculation discharges about 120 million to 150 million sperm each time.The total number of sperm is less than 60 million, and the pregnancy ability is reduced; less than 20 million, the chance of conception is very small.
How is young sperm disease formed?
Simple sperm disease is sperm -generated disorders. If there is a disease, there is a cause. What are the causes of sperm production?
According to relevant clinical data, the main factors that lead to young sperm disease are:
1. Decreased special sperm, long -term injecting androgen injection ofrogen, due to negative feedback effects that the hypothalamic gonadotropin release hormone is reduced, resulting in a reduction of gonad hormone secretion, resulting in sperm reduction or lack of lack;
2. The effect of drugs can directly or indirectly affect sperm production;
3. Radial irradiation, which is the most sensitive to naive cells, including sperm epithelium, can cause sperm cells to delay or stop, or even cause irreversible damage;
4. Other factors, alcohol poisoning, excessive smoking, and drugs can inhibit sperm production; chronic, sperm varicocele, etc. can inhibit sperm production.During the formation of sperm, it is adjusted by endocrine hormones. Any factors affecting sperm function will cause the number of sperm to decrease.
