Deprivation therapy is indicated for intermediate (gl =7, psa 10-20) and high risk (gl =/> 8/10; psa >20)prosca.
It is not curative. Seems most effective in gl 7. It prolongs time to psa rise, and a very small group may survive a little longer after 8-10 yrs. The older you are; the more risks, the fewer benefits. The longer the duration, imotence/libido
may be permanent.
