Hormone therapy is a prostate cancer treatment option that treats the cancer by depriving it of the male hormone androgen, which it needs to grow; this treatment option is also known as androgen deprivation therapy. It must be noted that hormone therapy can only slowed down the growth of cancer cells but not stopped stop them, therefore it is sometimes used with other treatment options.

There are two broad classes of hormone treatment therapy, that of orchiectomy (surgical castration) or drugs treatment such as Luteinizing Hormone-Releasing Hormone (LHRH) antagonists.

The testicles account for more than 95 percent of the testosterone production, the adrenal also produces a small amount. The Orchiectomy procedure involves the removal of the testicles from the scrotum; this results in a drastic fall in the amount of testosterone that is produced by the man. Orchiectomy is best and most often used in cases where the patient has advanced prostate cancer.

Hormone Therapy Side effects

The removal of large amounts of testosterone from the body can cause lots of problems and side effects, many of which are similar to those that a menopausal woman will have. However, most of these symptoms can be resolved with hormone replacement therapy. The Encyclopedia of Surgery lists the following as side effects of having an orchiectomy:
· loss of sexual desire (This side effect can be treated with hormone injections or gel preparations.)
· impotence
· hot flashes
· fatigue
· loss of sensation in the groin or the genitals
· osteoporosis (Men who are taking hormone treatments for prostate cancer are at greater risk of osteoporosis.)
· weight gain of 10–15 lb (4.5–6.8 kg)
· mood swings or depression
· enlargement and tenderness in the breasts

Other prostate cancer treatment options include:
· Brachytherapy Radiation
· Cryotherapy (cryosurgery)
· Radical Prostatectomy
· Watchful Waiting
· Herbal Alternatives
