Testosterone stimulates the prostate to grow.
When prostate cancer cells develop, they also rely on testosterone for continued growth. The goal of hormone therapy is to lower the level of androgens circulating in the body and slow the growth of prostate cancer. This may be done by blocking the production of testosterone or by blocking signals from the brain that tell the testicles and adrenal glands to produce testosterone.
