Does daily masturbation affect fertility, quantity and quality of sperm in the ejaculate?

See answer . Though there is likely some degree of variation from one individual to the next, daily or more frequent ejaculation is likely to diminish to some degree the quantity and quality of the sperm and therefore "potentially" the fertility as well. It is generally felt that 48-72 hours is the ideal time interval to maximize sperm and semen quality. If not trying to conceive, frequency is not an issue.
