Hypogonadotropic usually refers to hypogonadotropic hypogonadism. Hypogonadotropic hypogonadism can result in a decrease in sex hormone synthesis and secretion, which can lead to delayed puberty and, in adult patients, hypogonadism or infertility. Treatment includes etiologic therapy and hormone replacement therapy. Causes include pituitary tumors, which can be treated surgically. The purpose of hormone replacement therapy is to promote the development of secondary sex characteristics and maintain sexual function, and the principle of replacement therapy is to simulate the normal pubertal process. Patients with hypogonadotropic hypogonadism should go to the hospital for examination and treatment under the guidance of a doctor to avoid delays.
