Cyproterone has the ability to competitively bind to
tissue androgen receptors in target organs, reducing or completely
eliminating the effects of androgens (both endogenous and exogenous origin) in
target organs of men and women. In addition to the antiandrogenic effect
cyproterone has a powerful antigonadotropic and progestogenic effect.
In men, while taking cyproterone, there is a weakening of sexual desire and
decreased testicular function. Cyproterone reduces or completely eliminates the effects
androgens to the prostate.
