A synthetic hormone that blocks the effects of testosterone, used medically to treat conditions like prostate cancer, severe acne in women, and abnormal sexual development.
Blend from cyano- (chemistry prefix) + progesterone-like structure + -one (ketone chemical suffix), synthesized in the 1970s as an androgen antagonist for hormone therapy.
Cyproterone was accidentally discovered to reduce testosterone while testing other hormone treatments, and this accidental finding has been transformative for treating hormone-sensitive cancers—many modern medicines are discovered by scientific serendipity rather than direct design.
