What are the main causes of male infertility?

Infertility seems to be more and more common in life in recent years, especially among men. The increasing work pressure and bad eating habits are the root causes of male infertility. Below, let's take a detailed look at the causes of male infertility.

1. Sperm abnormality:

Such as no sperm, small sperm count, weak sperm activity, and abnormal sperm.

2. Testicular abnormalities:

For example, in the case of cryptorchidism, the infertility caused by a single case of cryptorchidism is about 30% to 60%; the infertility caused by bilateral cryptorchidism is about 50% to 100%, and it can also induce malignant changes.

3. Genital infection:

For example, bacterial, viral, and parasitic infections can directly damage the testicles, causing testicular atrophy, seriously affecting spermatogenesis and reducing sperm activity. For example, 20% of patients who have suffered from mumps during adolescence and then developed orchitis will suffer from infertility.

4. Smoking and drinking:

Medical research has found that male smokers have fewer sperm than normal men, indicating that smoking can kill sperm in the male body; and alcohol can cause sperm head and tail deformities, reduce vitality, and fail to combine normally with the egg, leading to male infertility.
