If you stop your hormone therapy, your testosterone levels will gradually rise again and some side effects will reduce. Your side effects won't stop as soon as you finish hormone therapy – it may take several months. Surgery to remove the testicles (orchidectomy) can't be reversed, so the side effects are permanent.
Is ADT a radiation?
These are the most common: * Intermediate-risk men who are given six months of ADT plus external-beam radiation; * High-risk men who are getting radiation therapy. This is a finite course of ADT, and this combination – two or three years of ADT plus external-beam radiation – has been proven to cure cancer in many men.
Does ADT lower PSA?
The presence of distant metastases at the initiation of ADT, a higher PSA nadir after ADT, a higher velocity of PSA decline, and a time to reach PSA nadir of <9 months are associated with an increased risk of progression to CRPC.

ADT has a lot of side effects, including a higher risk of cognitive impairment, but the biggest elephant in the room is the fact that men on ADT lose their sex drive and ability to have an erection.
What is ADT treatment?
Androgen deprivation therapy (ADT) for prostate cancer. Prostate cancer needs testosterone to grow. Reducing how much testosterone your body makes may slow the cancer’s growth or shrink the cancer temporarily. Testosterone is an androgen (male sex hormone), so this treatment is called androgen deprivation therapy (ADT).

What hormones are used to remove testicles?
Estrogens (female hormones) were once the main alternative to removing the testicles (orchiectomy) for men with advanced prostate cancer. Because of their possible side effects (including blood clots and breast enlargement), estrogens have been replaced by other types of hormone therapy.
What are the main androgens in the body?
The main androgens in the body are testosterone and dihydrotestosterone (DHT). Most androgen is made by the testicles, but the adrenal glands (glands that sit above your kidneys) as well as the prostate cancer itself, can also make a fair amount.
Is prostate cancer permanent?
It is probably the least expensive and simplest form of hormone therapy. But unlike some of the other treatments, it is permanent, and many men have trouble accepting the remo val of their testicles.
What is the effect of orchiectomy?
Orchiectomy (surgical castration) Even though this is a type of surgery, its main effect is as a form of hormone therapy. In this operation, the surgeon removes the testicles, where most of the androgens (such as testosterone and DHT) are made. This causes most prostate cancers to stop growing or shrink for a time.
Can LHRH antagonists cause prostate cancer?
LHRH antagonists can be used to treat advanced prostate cancer. These drugs work in a slightly different way from the LHRH agonists, but they lower testosterone levels more quickly and don’t cause tumor flare like the LHRH agonists do. Treatment with these drugs can also be considered a form of medical castration.
What is the receptor that helps prostate cancer cells grow?
For most prostate cancer cells to grow, androgens have to attach to a protein in the prostate cancer cell called an androgen receptor . Anti-androgens are drugs that also connect to these receptors, keeping the androgens from causing tumor growth. Anti-androgens are also sometimes called androgen receptor antagonists.
What is the procedure to remove testicles?
This form of hormone therapy (also called androgen deprivation therapy, or ADT) includes: Orchiectomy, a surgical procedure to remove one or both testicles. Removal of the testicles, called surgical castration , can reduce the level of testosterone in the blood by 90% to 95% ( 5 ).
What is the LHRH agonist?

Treatments that reduce androgen production by the testicles are the most commonly used hormone therapies for prostate cancer and the first type of hormone therapy that most men with prostate cancer receive. This form of hormone therapy (also called androgen deprivation therapy, or ADT) includes:
Which hormone is responsible for the production of testosterone?
Drawing shows that testosterone production is regulated by luteinizing hormone (LH) and luteinizing hormone-releasing hormone (LHRH). The hypothalamus releases LHRH, which stimulates the release of LH from the pituitary gland. LH acts on specific cells in the testes to produce the majority of testosterone in the body.
Does exercise help with bone loss?
However, drugs to treat bone loss are associated with a rare but serious side effect called osteonecrosis of the jaw ( 20 ). Exercise may help reduce some of the side effects of hormone therapy, including bone loss, muscle loss, weight gain, fatigue, and insulin resistance ( 20, 32 ).
What does it mean when your PSA is high?
An increase in PSA level may indicate that a man’s cancer has started growing again. A PSA level that continues to increase while hormone therapy is successfully keeping androgen levels extremely low is an indicator that a man’s prostate cancer has become resistant to the hormone therapy that is currently being used.
Where are androgens produced?
Most of the remaining androgens are produced by the adrenal glands . Androgens are taken up by prostate cells, where they either bind to the androgen receptor directly or are converted to dihydrotestosterone (DHT), which has a greater binding affinity for the androgen receptor than testosterone.

[20-22] Retrospective studies have found that men on ADT for nonmetastatic prostate cancer had a median weight gain of 1 to 2 kg after 1 year ...
Is ADT associated with CVD?
There are conflicting data on the risk of cardiovascular disease (CVD) with use of ADT. Currently, there are no prospective randomized controlled data assessing the association of ADT use with risk of CVD. In a large retrospective population-based cohort study, multivariate analyses demonstrated that men with newly diagnosed prostate cancer who received ADT had a 20% increased risk of CVD. [41] Somewhat paradoxically, the study found that men receiving treatment for less than 12 months were at higher risk for cardiovascular events compared with men who had been on ADT for longer. A major limitation of this study is that the researchers were unable to control for smoking and obesity, which are two major risk factors for CVD and could confound the results. Additionally, age was a major variable associated with CVD. A meta-analysis of eight large trials found no significant differences in risk of CVD in patients receiving ADT vs controls, nor was duration of ADT significantly associated with increased risk of CVD. [42]
Can men with prostate cancer take ADT?
Currently, no specific recommendation adjustments for men with prostate cancer receiving ADT should be pursued outside of primary prevention, including smoking cessation, and secondary prevention, including glycemic control, lipid-lowering therapy, and aspirin therapy for men with coronary artery disease.
Does ADT cause hot flushes?
Hot flushes are one of the most common and bothersome side effects associated with ADT. Up to 80% of patients undergoing treatment with GnRH agonists will experience hot flushes, with 27% of these patients reporting this symptom as the most significant adverse side effect. [3] .
Does EBRT cause erectile dysfunction?
Several studies have shown that treatment for clinically localized prostate cancer involving either radical prostatectomy, brachytherapy, or external beam radiotherapy (EBRT) can result in long-term erectile dysfunction. [9,10] Patients receiving neoadjuvant ADT with EBRT were found to have decreased frequency of erection, decreased overall sexual function, and an increase in frequency of hot flushes. [11] In addition, loss of libido is a major consequence of ADT. The degree of erectile dysfunction for patients on ADT is impacted by pretreatment sexual function, as well as by changes in libido; in patients previously able to attain an erection, phosphodiesterase 5 inhibitors, intracavernosal injection therapy, vacuum-assisted devices, or other topical agents may be used. Given the complex interplay between physiology, psychology, stress, and emotion involved in sexual function, a referral to a psychology or counseling service with a focus on sexual health is recommended for interested patients and their partners.
What are the side effects of ADT?
Often called chemical castration, the effects mimic those in men who have had both testicles removed (orchiectomies, also known as surgical castration.)

Does ADT cause prostate cancer?
The combination of ADT plus an anti-androgen drug shuts off the supply of testosterone, which is the fuel that drives prostate cancer growth. Traditionally this had been accomplished with ADT + a non-steroidal anti-androgen medication.
Does Xtandi delay chemotherapy?
Results of a phase III trial reported at the 2014 American Society of Clinical Oncology Annual Meeting demonstrated that treatment with Xtandi® significantly delays the need for chemotherapy in metastatic prostate cancer patients previously treated with hormone therapy.
