What are the causes of male infertility?

Patient's question:

Previously, my wife had blocked fallopian tubes, so we couldn't have children. Now, more than six months after the surgery, there's still no sign of pregnancy. A few days ago, I went for a check-up, and the doctor told me it was my problem—I have male infertility. I feel very desperate now. Could you please tell me: What are the causes of male infertility?

Doctor's answer:

1. Smoking, drug use, and pesticide residues can also interfere with the quality and quantity of sperm.
2. Poor lifestyle habits, such as disliking leather or denim pants, wearing synthetic underwear, or taking saunas, can lead to a decrease in scrotal temperature, disrupting sperm development and vitality.
3. The destruction of the blood-testis barrier can expose sperm antigens to the body's immune system, leading to the production of anti-sperm antibodies that cause sperm agglutination or immobilization, impairing sperm vitality. A deficiency in trace elements can severely affect sperm motility, especially a lack of zinc. For infertility patients, timely treatment can reduce the incidence, but if left untreated, it may affect overall health. Therefore, patients should seek timely and targeted treatment, maintain regular sexual activity in daily life, and avoid prolonged sitting. Wishing you a speedy recovery.
