<unk>  is available in pharmaceutical formulations for medical use as an androgen. It is used mainly as a form of androgen replacement therapy in the treatment of male hypogonadism and is specifically approved for this indication in certain countries. However, it is no longer recommended for this purpose due to biological differences from testosterone such as lack of estrogenic effects and partial androgenic effects. Topical<unk>  is useful in the treatment of gynecomastia. Similarly,<unk>  enanthate via intramuscular injection has been found to be effective in the treatment persistent pubertal gynecomastia. The medication has also been used as a topical gel to treat small penis in pre- and peripubertal boys with mild or partial androgen insensitivity syndrome.<unk>  was found to be effective in the treatment of advanced breast cancer in women in the 1950s, although it was used in very high doses and caused severe virilization. It was used as a microcrystalline aqueous suspension by intramuscular injection. Shortly thereafter, drostanolone propionate (2α-methylandrostanolone propionate) was developed for this use instead of<unk>  due to its superior pharmacokinetics and was introduced for this indication in the United States and Europe in the early 1960s.<unk>  was used at a dose of 25 mg sublingually two to three times per day in androgen replacement therapy for men.
