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
