1. Male Infertility Causes
1. Genetic factors: KLINEFELTER syndrome, male Turner syndrome, etc. with abnormal chromosomes.
2, semen abnormalities: if there is no sperm or the number of sperm is too small, the activity is weakened, and the form is abnormal.
3. Abnormal testicles: There are three cases of testicles abnormal: 1) Cultivation tests, and the infertility caused by unilateral neck tests is about 30%to 60%, and the bilateral sides are 50%to 100%.Not only leads to infertility, but it can also induce malignant changes; 2) The fetal period is damaged due to adverse environmental factors; 3) early testicular injuries, which can be caused by domestic injuries during childbirth.
4. Testes are damaged after testicular: such as hernia repair, sheath effusion surgery, and testicular fixing surgery, which damage the testicular blood vessels, hindering the blood supply and the testicular atrophy.
5. Sperm transportation is blocked: The tuberculosis of the epididymis and the vollar tube can block the vascular vapor, hinder the passage of sperm, and premature ejaculation cannot enter the female vagina.
6. Chronic diseases and infertility: such as thyroid disease, liver disease, diabetes, renal failure, etc. can cause infertility.
7. Infertility caused by psychological and psychological factors: The abnormal mental and psychological state of the patient causes the nerve endocrine to disorder and cause the testicular sperm function to be low, or cause sexual intercourse dysfunction to cause infertility.
8. Hydrogen effusion: The hydrocele compresss the testicular blood circulation, which can cause testicular infection or atrophy.The incidence of this disease was 16%& mdash; 19%.
9. Endocrine factors: Men's endocrine is subject to the hypothalamus-pituitary-testicular axis. The minor sperm and non-sperm disease caused by dysfunction caused by dysfunction caused by dysfunction caused by dysfunction of the pituitary, thyroid and adrenaline dysfunction can cause infertility.
10. Gravity impact: Men can reduce the endogenous sperm of the testicles under excessive weights and cause infertility.
11. Immune factors: Because sperm exposes the immune system, sperm pulp produces antibodies against their sperm in the body. The ejected sperm has its own condensation and cannot conceive women.
12. Reproductive organs infection: Bacteria, viruses, raw insects and other infections can directly damage the testicular, leading to testicular atrophy, testicular tuberculosis, destroying testicular tissue, seriously affecting sperm's ability and reducing sperm activity and leading to infertility.For example, 20%of mumps in the early stage of youth development cause infertility.
13. Infertility caused by neurological dysfunction and neurological diseases: such as paraplegia and impotence.
