It's well worth reading Dr Myers book, "Beating Prostate Cancer: Hormonal Therapy & Diet".
He has sections on two common myths about hormonal therapy, and several case studies of patients he has treated for some time who had PSA readings of 3488 3656 and 1026, and now have very low readings.
I know a number of men using hormone treatment. Most cope well with it and have few side effects. One has his story on the yananow site under mentors experiences.
