Androgen suppression

Androgen suppression, also known as testosterone suppression, is a medical treatment to suppress or block the production or action of male sex hormones, typically used against certain cancers that rely on male growth hormones. This a done by castration (sometimes chemical castration) or by prescribing female sex hormones and drugs called antiandrogens. It is employed in androgen deprivation therapy for prostate cancer, feminizing hormone therapy for transgender women and against other androgen-dependent conditions.
