Androgens during Infancy, Childhood, and Adolescence: Physiology and use in clinical practice.

Androgens during Infancy, Childhood, and Adolescence: Physiology and use in clinical practice. Endocr Rev. 2020 Mar 02;: Authors: Mason KA, Schoelwer MJ, Rogol AD Abstract We provide an in-depth review of the role of androgens in male maturation and development from the fetal stage through adolescence into emerging adulthood and discuss the treatment of disorders of androgen production throughout these time periods. Testosterone, the primary androgen produced by males, has both anabolic and androgenic effects. Androgen exposure induces virilization and anabolic body composition changes during fetal development, influences growth and virilization during infancy and stimulates development of secondary sexual characteristics, growth acceleration, bone mass accrual, and alterations of body composition during puberty. Disorders of androgen production may be subdivided into hypo- or hypergonadotropic hypogonadism. Hypogonadotropic hypogonadism may be congenital or acquired, resulting from cranial radiation or trauma, although there are many less common causes. Hypergonadotropic hypogonadism occurs in males with Klinefelter syndrome and may occur in response to pelvic radiation, certain chemotherapeutic agents, and other less common causes. These disorders all require testosterone replacement therapy during pubertal maturation and many require life-long replacement. Androgen (or gonadotropin) therapy is clearly beneficial in those with pers...
