3.more  details:

CPA has been in use as an antiandrogen since 1964, and was the

first antiandrogen introduced for clinical use.It is widely

used throughout Europe, and is also used in Canada, Mexico, and

other countries. It is not FDA-approved for use in the United

States, due to concerns about hepatotoxicity;

medroxyprogesterone acetate has been used in this country

instead.CPA has been approved for the treatment of prostate

cancer, precocious puberty, androgen-related dermatological

conditions (such as acne, seborrhea, hirsutism, and androgenic

alopecia), and to reduce sex drive in sex offenders.Combination

formulations of CPA with ethinyl estradiol (a formulation

sometimes referred to as co-cyprindiol) have been available as

contraceptives since 1997.

Other uses of CPA include the treatment of benign prostatic

hyperplasia, priapism, hypersexuality, paraphilias, hot

flashes, and hyperandrogenism in women. In addition, with the

exception of the United States (where CPA is not available and

is generally employed instead), CPA is widely

used as a component of hormone replacement therapy for trans
Androgen deprivation, used to treat male benign
Hypertrophy of the prostate, and can be used as a male contraceptive pill
