Many infertility disorders are the result of not paying attention to prevention during adolescence or even childhood. Therefore, during early childhood, parents should let them know some hygiene knowledge and pay attention to and detect some problems in time to reduce the occurrence of infertility. For children nearing puberty, parents should explain some knowledge of puberty hygiene to them in time. Girls should be taught to pay attention to menstrual hygiene after puberty and go to the hospital early if abnormalities are found. When a gynecological examination is needed, do not refrain from treating the problem so as not to delay the treatment period and cause irreversible damage (such as hymenal atresia). A young girl with late menstruation may be a sign of delayed puberty, indicating late maturation of sexual function and should be married appropriately late. If married too early, they are prone to menstrual disorders and infectious diseases of the reproductive organs. For boys, the presence or absence of testicles in the scrotum and their development should be noted from birth. If the testicles have not dropped after one week of age, or if other abnormalities are found, you should go to the hospital in time to avoid missing the best treatment period. If the cryptomonads reach puberty, even after surgical reset, the spermatogenic function will not recover due to severe damage. During the mumps epidemic season, attention should be paid to active prevention, and in case of illness, the testicles should be kept in check and treated promptly. Vaccination with BCG vaccine is an important means to prevent tuberculosis and a fundamental measure to prevent the occurrence of tuberculosis of the fallopian tube and tuberculosis of the attachment sheet. In addition, during adolescence, attention should be paid to the protection of the genital organs, to prevent damage to the testicles due to falls, to prevent exposure to strong radiation, and not to wear tight pants for a long time. Only with good prevention from early childhood will the incidence of infertility in adulthood be significantly reduced.
