Patient's question:
Brother-in-law is already 32 years old, and sister still doesn't have children. They've been married for many years. Brother-in-law suffers from infertility, and despite all these years, it hasn't been effectively treated. They don't know what factors or causes it could be. How could this happen? They hope he can be cured.Doctor's answer:
Hello, long-term excessive drinking and smoking can cause impotence, abnormal ejaculation function, and even lead to abnormal sperm quality, resulting in infertility or fetal malformations. It is essential for every patient to clearly understand that malnutrition can cause a deficiency in proteins, vitamins, and trace elements, affecting sperm production and capacitation, leading to abnormalities in sperm quantity and quality, and similarly causing male infertility.
