Castrate level occurs
when the levels of the body’s
testosterone drop 90 to 95 percent, consistent with
the loss of the testicles. The testicles produce around
90 percent of a man’s testosterone. The traditional
form of castration would remove testicles, so the loss
of the ability to produce testosterone is called castrate
level. In prostate cancer hormone therapy, surgical
castration or chemical castration is used to ablate
testosterone. Testosterone fuels the production of the
prostate gland cells and the prostate cancer tumor.
The removal of testosterone from the body will temporarily
stop or slow the growth of the cancer.
