Theoretically, starting to masturbate at the age of 14 will not have an effect on fertility, but you need to control the frequency. The majority of the masturbation starts at the age of 12-16, the average age is 14, so it is said that starting to masturbate at the age of 14 does not affect fertility, but it must be under the premise of moderate masturbation. If you’re a frequent masturbator, the penis will be congested for a long time, which can easily lead to prostatitis or urethritis, which can seriously cause impotence and premature ejaculation, which can lead to impaired fertility. Therefore, it is not recommended to develop the habit of frequent masturbation at the age of 14. Students should focus more on their studies and other aspects to avoid exposure to obscene content, and seek medical help if necessary.
