Patient's question:

I have been married to my wife for many years, and we have not taken any contraceptive measures, but we have never had children. After checking at the hospital, I was diagnosed with a disease. Please ask, what check-up items are usually required for dead sperm?

Doctor's answer:

Prevention of Dead Sperm
For the prevention of asthenozoospermia (male infertility), it is essential to have certain sexual knowledge and understand male physiological characteristics and health care. If any abnormalities are noticed in the testicles, such as swelling, hardness, unevenness, or pain, it is crucial to seek medical attention promptly.
The testicles are a very delicate organ, and their optimal working temperature is about 1 degree lower than the human body temperature. If the temperature rises, it can interfere with sperm production. Therefore, any factors that may lower testicular temperature should be avoided. First and foremost, it is important to receive vaccinations on schedule and maintain good personal hygiene habits to prevent various infectious diseases that can harm male fertility, such as mumps and sexually transmitted infections.
