How is low sperm count caused

Patient's question:

Married for many years without having children, the check revealed that I suffer from oligospermia. How is oligospermia caused

Doctor's answer:

Reproductive system infections are one of the main causes of male oligozoospermia. Bacteria, viruses, mycoplasma, chlamydia, and other infections can lead to recurrent oligozoospermia in men. Long-term standing, excessive physical labor, and other factors can cause varicocele in men, a condition that interferes with spermatogonial cells and disrupts the development of sperm.
With this, I hope male friends have a better understanding of the causes of oligozoospermia. Therefore, in daily life, men should pay more attention to this symptom and take measures to prevent the occurrence of this disease.
