Delayed genital development in boys may be caused by androgen deficiency, prepuce, hypospadias, etc. General treatment, medication and surgery are often used in clinical practice. 1. Androgen insufficiency: If a boy suffers from metabolic diseases or long-term malnutrition, it will cause androgen insufficiency, resulting in delayed genital development. It is recommended that patients eat more food rich in dietary fiber and high-quality protein, such as fish, lean meat, fruits and vegetables, etc., to consume sufficient nutrition and increase their own immunity, which will help alleviate the symptoms. 2. Phimosis: If the patient has a phimosis, it will also affect the development of the genitals. In children, the doctor can first try to dilate the opening of the foreskin by manipulation; the foreskin can also be treated with a foreskin expander; circumcision can be performed if necessary, which can help to relieve the symptoms. 3. Hypospadias: mainly due to the disorder of embryonic development process, the urethral groove is not completely fused to the distal part of the glans, and the urethral opening is located anywhere between the coronal sulcus and the perineum, which may lead to delayed genital development in boys. Clinical recommendations are based on surgical treatment, such as penile curvature correction and urethroplasty. Therefore, there are more causes of delayed genital development in boys, so you should choose to seek medical treatment early and follow the doctor’s advice for early treatment, avoiding unauthorized use of medication.
