It is recommended to seek timely medical advice and give reasonable treatment to improve the situation of delayed genital development to the greatest extent.1. Insufficient hormone secretion: If children suffer from metabolic diseases or malnutrition, it can lead to insufficient secretion of estrogen and androgen in the body, and thus the phenomenon of delayed development. If the hormone secretion deficiency is caused by long-term malnutrition, attention should be paid to adjusting the diet to ensure that children take in sufficient nutrition. If the hormone secretion is insufficient due to diseases, such as pituitary gland function defects, resulting in a decrease in the secretion of luteinizing hormone, resulting in insufficient androgen secretion, testosterone treatment can be applied under the guidance of a doctor. 2. Genetic factors: If there are family members with genital developmental delay, the offspring may also have the problem of developmental delay. Genetically induced genital development retardation requires timely treatment at a hospital, such as congenital small penis, which can be treated with GnRH pulse therapy, gonadotropin and androgen replacement therapy, either alone or in combination.
