How does it work?

Androcur 50mg tablets contain the active ingredient cyproterone acetate, which is a type of medicine known as an anti-androgen. Cyproterone acetate is also available without a brand name, ie as the generic medicine.

Androgens are male hormones such as testosterone. Testosterone is produced by the testicles and is the main hormone essential for normal growth and development of the male sex organs and male sexual characteristics. During adult life, testosterone is essential for the production of sperm, the maintenance of sex drive, erectile potency, and the functioning of the prostate gland and other reproductive structures.

Cyproterone acts on an area of the brain called the hypothalamus and causes a reduction in the amount of testosterone produced by the body. It also prevents testosterone from binding to androgen receptors in other areas of the body. The result of this is a decrease in the amount of testosterone circulating in the body, which can help control sexual desire.

Androcur  50mg tablets are used to control sex drive in men with severe hypersexuality and or sexual deviation. Sexual deviation refers to men who prefer sexual practices that are biologically abnormal or considered morally wrong or illegal, for example paedophilia or bestiality.
