Question
Is regular masturbation or sexual intercourse harmful to fertility?
Answer
Regular masturbation and sexual intercourse are not harmful to fertility. To standardise semen analysis, the World Health Organisation states that there be a two to seven-day period of abstinence before the sample is collected. The longer period between the ejaculation, the greater the volume of semen and the higher the total number of sperm released. Ejaculating daily, or even more frequently, won't cause any damage; rather, it will just decrease the number of sperm in each ejaculate, but over the period of a week, you'll still make the same number of sperm.
The advice for people who are trying to get pregnant is that they should have intercourse at least every second day across the fertile week of the month.
