Hormone therapy is delivered via an injection of a long-lasting drug into the patient’s body. This drug is usually called a lutenizing releasing agonist or LHRH agonist. Some formulations last up to 6 months. Another drug, called an LHRH antagonist, works faster than the agonist but does not last as long. There are pros and cons for both drugs. The drugs must repeatedly be injected and can be very costly if they are not covered by the patient’s insurance plan.
Another method of hormone therapy involves the removal of the portion of the testicles that produce testosterone. This is called a simple bilateral orchiectomy, an irreversible procedure that reduces testosterone levels more effectively than drugs and is less expensive. Usually the removal is an outpatient procedure done in the hospital.
