Medical action:

Cyproterone belongs to a group of medications known as steroidal antiandrogens. It is used to treat advanced prostate cancer. Antiandrogens such as cyproterone block the effect of the hormone called testosterone. This causes a reduction in the production of testosterone in the testicles, which prostate cancer cells require for growth.
