Patient's question:
Hello doctor, I would like to ask how long it takes for a man's sperm to regenerate? My wife and I are planning to have a child. If I have intercourse with my wife today and ejaculate once, how long should I wait to produce sperm that is capable of fertilization? Some people say it takes 90 days, is that really so long??? How long does it take for a man's sperm to regenerate?Doctor's answer:
Hello, the maturation time of sperm is approximately 64-72 days. It stays in the epididymis for about 19-25 days to further mature, so the entire maturation process of sperm takes about 90 days. Sperm is produced in the testes through circulation, and after sperm is expelled, a new batch of sperm is generated.
