How many weeks does a mature spermatazoan typically survive?

4‐6 weeks

Mature sperm survive in the epididymis for approximately 4 to 6 weeks before being ejaculated or being catabolized and resorbed. A man is informed that he can father a child for up to 6 weeks following a vasectomy. Most urologists and or vasectomy clinics will test a mans sperm count after 20 ejaculations or 6 weeks following a vasectomy. Sperm are able to survive for this extended duration due to the lower temperatures within the scrotum. In the female reproductive tract, most sperm die within 2448 after ejaculation, although viable sperm can be recovered up to 5 days after a single ejaculation during intercourse.
