Does unilateral vas deferens blockage affect fertility?

Patient's question:

Hello, my wife and I have been married for one year and four months. We have never used any form of contraception, thinking that if we conceive, we will just let it happen. However, more than a year has passed, and she still hasn't become pregnant. I had my vas deferens checked, and after the doctor examined it, they said it is blocked on one side. What are the effects of this condition on fertility?

Doctor's answer:

Hello, unilateral vas deferens obstruction has little impact on fertility; when bilateral obstruction occurs, sperm cannot be expelled normally, leading to infertility. The main factors or causes include congenital underdevelopment or malformation of the vas deferens, infection, tumors, trauma, or surgery. It is recommended to combine your specific examination results and seek timely treatment. During treatment, avoid spicy foods. There are many factors that can cause vas deferens obstruction, and patients need to respond promptly to the symptoms. It is advisable to seek treatment at a reputable hospital for your condition. Pay attention to the progression of your condition, avoid indiscriminate treatment, and prioritize self-care, including a balanced diet, maintaining cleanliness, and best wishes for your recovery!
