Will I run out of sperm if I ejaculate too many times a day?

There’s no limit in the amount of sperm that a man can produce. If you ejaculate several times in a row, while you may have less sperm in each subsequent ejaculation, it will return to normal levels within a day. Scientists recommend frequent ejaculation to help keep your prostate healthy. So, have all the orgasms you want without fearing that your sperm will ever run out. In fact, you can learn to have an orgasm without ejaculation, but that is another topic we will deal with.
