The disappearance of the epiphyses at the ends of the long bones is clinically known as epiphyseal closure. When the epiphyses close, the bones stop developing. Masturbation does not cause the epiphyses to close prematurely. Moderate masturbation itself will not bring damage to the body. However, frequent masturbation may bring about some negative consequences in terms of sexual function, such as premature ejaculation, impotence and other problems. Excessive masturbation, if not corrected in time, can lead to neurasthenia and genitourinary disorders as well as sexual dysfunction, so moderation is recommended. The early closure of epiphysis is mostly related to heredity, diet, nutrition and exercise. Pay attention to diet and nutrition on weekdays, eat more food rich in protein, vitamin D and calcium and other substances, such as milk, fish, meat, vegetables, fruits, etc., to slow down the epiphysis of the closure of the epiphysis has a certain effect.
