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 oligospermia. Bacterial, viral, mycoplasma, chlamydia, and other infections can lead to recurrent oligospermia 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 understanding of the causes of oligospermia, men should pay more attention to this symptom in daily life to prevent the occurrence of this disease.
