Patient's question:
Hello doctor, I would like to ask how long it takes for a man's sperm to renew? My wife and I are planning to have a child. If I have sex with my wife today and ejaculate once, how long do I need to 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 renew?Doctor's answer:
The date of ovulation is generally about 14 days before the next menstrual period. Starting from the first day of the next menstrual period, subtracting 14 days or counting backward 14 days gives the ovulation day. The ovulation day, along with the 5 days before it and the 4 days after it, together constitute the fertile window. The specific calculation depends on your menstrual cycle, and it requires an extremely accurate menstrual cycle to ensure the correctly calculated fertile window.Advice: If you want to get pregnant, you can start from the first day of your fertile window, having intercourse every two days. If there are no special circumstances, you will usually become pregnant.
