Be alert to the ten external causes of male infertility and five behaviors that may easily lead to infertility

Male infertility is caused by a variety of comprehensive factors, not an independent clinical disease. External factors of male infertility include

1. Infertility due to blood supply disorder

Arteriosclerosis patients and diabetes patients, accompanied by testicular arteriole disease, sperm capacity decline infertility.

2. Mental factors lead to infertility

Mental depression, fear or excessive tension often lead to infertility due to erectile decline.

3. Drugs and drug infertility

Such as nicotine, alcohol, anesthetics, sedatives, antihypertensive drugs and hormonal drugs not only affect male function, but also affect testicular spermatogenesis function infertility.

4. Infertility due to mumps sequelae

20% of mumps in early puberty are accompanied by orchitis and infertility. What is serious is that mumps virus will cause testicular tissue atrophy, leading to orchitis, and the tissue of the seminiferous tubules will be destroyed. Accompanied by testicular swelling and pain, fever, chills, nausea, vomiting and other systemic symptoms.

5. Sterility due to genital infection

If infected with bacteria, viruses, protozoa, etc., it can directly damage the testis and seriously affect the sperm activity and sperm activity.

6. Abnormal testicular infertility

Acquired injury: herniorrhaphy, hydrocele surgery, testicular fixation surgery and other operations that damage the testicular blood vessels damage the embryonic base and early testicular injury due to adverse environmental factors in the fetal period, which can cause damage during delivery.

7. Immune factors lead to infertility

Because the sperm is exposed to the immune system, the sperm plasma produces antibodies against its own sperm in the body, and the ejaculated sperm agglutinates itself and cannot make women pregnant.

8. Respiratory diseases lead to infertility

For example, Young's syndrome and Kartagner's syndrome both cause infertility due to abnormal ultrastructure of respiratory mucosal cilia and sperm tail.

9. Infertility caused by hydrocele of tunica vaginalis

The hydrocele of the tunica vaginalis compresses the blood circulation of the testis, which can lead to infection or atrophy of the testis. The incidence rate of the disease after puberty is 16% - 19%.

10. Environmental impact on sterility

When miners and boiler workers who are overheated in the pit smoke too much, drink too much and lack oxygen, they will affect their fertility.

Five behaviors easily lead to infertility

Don't take a bath at too high temperature

Under normal circumstances, sperm can only develop normally in a constant temperature environment of 34 ℃~35 ℃. Too high water temperature in the bath often leads to "killing". For example, the room temperature in the sauna can be as high as 70 ℃ - 80 ℃, which is more than twice the temperature in the normal bathroom, which is not conducive to the growth of sperm, or causes too many "dead sperm" and leads to infertility.
