androgen replacement therapy

Also found in: Wikipedia.

androgen replacement therapy

The administration of androgens (e.g., testosterone or its congeners) in men with hypogonadal androgen-deficiency, which may be primary or secondary and either congenital or acquired. The intent of ART is to restore normal physiologic effects of testosterone, which depend on the stage of sexual development.

In androgen-deficient boys, the goal of ART is to initiate and maintain androgen-dependent activities, including somatic development (e.g., development of skeletal muscle and increased strength, long bone growth, redistribution of body fat and erythropoiesis), sexual behaviour (increased libido and potency) and development of 2º sexual characteristics (e.g., male pattern of hair growth, penile and scrotal enlargement, laryngeal enlargement and thickening of the vocal cords, and deepening of the voice).
