1. Testicular abnormalities: There are three types of testicular abnormalities:
① Cryptorchidism not only leads to infertility, but also induces malignancy;
② Fetal damage to embryonic primordia due to adverse environmental factors;
③ Early testicular injury can be caused by injury during childbirth.
2. Chromosome abnormalities: such as hermaphroditism, reproductive organ dysplasia, etc.
3. Acquired testicular injury: such as hernia repair surgery, hydrocele surgery, testicular fixation surgery, etc., damage testicular blood vessels, hinder blood supply, and cause testicular atrophy.
4. Hydrocele of the tunica vaginalis: Hydrocele of the tunica vaginalis compresses the blood circulation of the testes, which can lead to testicular infection or atrophy. The incidence rate of the disease after puberty is 16% - 19%.
5. Gravity effect: Men can reduce testicular spermatogenesis and lead to infertility when subjected to excessive weight bearing.
6. Psychological factors: Those who are excessively nervous often experience infertility due to poor erectile function.
7. Blood supply disorder: arteriosclerosis patients and diabetes patients are often accompanied by testicular arteriole disease, which makes the ability to produce sperm decline and cause infertility.
8. Drugs and drug effects: Excessive amounts such as nicotine, alcohol, opium, etc. can all affect sperm production. Anti epileptic drugs have a direct impact on spermatogenesis.
9. Environmental impact: miners and boiler workers who overheat in the tunnel; Underwear is too tight; Excessive smoking and drinking; Under hypoxic conditions, it can affect fertility.
10. Genital organ infection: Infections such as bacteria, viruses, and pathogens can directly damage the testes, seriously affecting sperm production ability and reducing sperm activity, leading to infertility. For example, 20% of cases of mumps in the early stages of puberty are accompanied by orchitis, resulting in infertility.
