Patient's question:
I want to know that men have semen, but there are no sperm in the semen. I have had two tests, and the doctors who treated me said there were no sperm. We are still trying to have a child recently. What are the causes of a man not having sperm?Doctor's answer:
No sperm, one possibility is a blocked vas deferens, and the other is that the testicles do not have the function of producing sperm. In your case, you need to do a testicular biopsy and a vasography. If it is a blocked vas deferens, it can be cleared. The vasography mainly applies to male infertility suspected to be caused by blocked vas deferens. For example, if there are no sperm in the semen but the testicular biopsy shows normal sperm production function, the vasography can clearly determine whether the vas deferens is blocked and the specific location of the blockage, so that corresponding treatment measures can be taken. If it is that the testicles do not have the function of producing sperm, then it is quite troublesome.
