Blog Can a Man Run Out of Sperm?

Question

Is it possible to have too many orgasms or ejaculations? Can a man ever run out of sperm?

Answer

This is a very common myth, but no, there is not a limited amount of sperm in a man's body. He can have all the orgasms he wants without ever running out. While it is true that if a man ejaculates several times in a row, he will have less sperm in each subsequent ejaculation, it will return to normal levels within a day.

The testicles contain a series of small tubes known as the seminiferous tubules. It is within these structures that spermatogenesis (sperm production) takes place. After puberty, a healthy man will produce hundreds of millions of sperm every day.

Infertility occurs when there is some type of malfunction in spermatogenesis or in the sperm reaching the penis. But it never occurs because a man has "run out" of sperm. Indeed, unlike women, men never go through a stage like menopause -- they will continue to produce sperm until they die.

So there is no need to worry. In fact, recent studies have found that frequent ejaculation helps keep the prostate healthy, which is an important part of fertility!
