I am forty years old, without sperm-producing cells, and have been treated at major hospitals in Wuhan without improvement.

Patient's question:

Married for fifteen years without children, blood tests and testicular biopsies have been done, checked at hospitals in Hubei Province, Wuhan Tongji has also been examined.

Doctor's answer:

Hello, according to your description, there are several common reasons why sperm production may be reduced in general germ cells. These include:
Congenital developmental abnormalities: Such as bilateral cryptorchidism, congenital testicular dysgenesis.
Systemic factors: Long-term malnutrition, smoking, excessive alcohol consumption, excessive mental stress, and frequent sexual activity.
Local factors: Orchitis complicated by mumps, testicular tuberculosis, varicocele.
Only by identifying the cause can we discuss the possibility of treatment.
