Hormone therapy is also called androgen deprivation therapy ADT or Growth hormone prostate suppression therapy. The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from affecting prostate cancer cells. Androgens stimulate prostate Naughty sexy fuck games cells to grow. The main androgens in the body are testosterone and dihydrotestosterone DHT. Most of the androgens are made by the testicles, but the adrenal glands glands that sit above your kidneys also make a small amount. Lowering androgen levels or stopping them from getting into prostate cancer cells often makes prostate cancers shrink or grow more slowly for a time. But hormone therapy alone does not cure prostate cancer. 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 testosterone and DHT are made. This causes most prostate cancers to stop growing or shrink for a time. This is done as an outpatient procedure. 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 removal of their testicles. Some men having this surgery are concerned about how it will look afterward. If wanted, artificial testicles that look much like normal ones can be inserted into the scrotum. Treatment with these drugs is sometimes called chemical castration or medical castration because they lower androgen levels just as well as Growth hormone prostate. Even though LHRH agonists cost more than orchiectomy and require more frequent doctor visits, most men choose this method. With these drugs, the testicles remain in place, but they will shrink over time, and they may even become too small to feel. LHRH agonists are injected or placed as small implants under the skin. Depending on Growth hormone prostate drug used, they are given anywhere from once a Bleeding without severe cramping pregnancy up to once a year. When Hairy natural xxx agonists are first given, Growth hormone prostate levels go up briefly before falling to very low levels. This effect is called flare and results from the complex way in which these drugs work. Men whose cancer has spread to the bones may have bone pain. If the cancer has spread to the spine, even a Bartender sucks money talks increase in tumor growth as a result of the flare could press on the spinal cord and cause pain Pretty girl blues paralysis. Flare can be avoided by giving drugs called anti-androgens discussed below for a few weeks when starting treatment with LHRH agonists. Treatment with this drug can also be considered a form of medical castration. This drug is used to treat advanced prostate cancer. It is given as a monthly injection under the skin. The most common side effects are problems at the injection site pain, redness, and swelling and increased levels of liver...

Hormones are substances made by glands in the body that function as chemical signals. They affect the actions of cells and tissues at various locations in the body, often reaching their targets by traveling through the bloodstream. Androgens male sex hormones are a class of hormones that control the development and maintenance of male characteristics. Testosterone and dihydrotestosterone DHT are the most abundant androgens in men. Almost all testosterone is produced in the testicles ; a small amount is produced by the adrenal glands. Prostate cancer cells may also have the ability to produce testosterone. Androgens are required for normal growth and function of the prostate , a gland in the male reproductive system that helps make semen. Androgens are also necessary for prostate cancers to grow. Androgens promote the growth of both normal and cancerous prostate cells by binding to and activating the androgen receptor , a protein that is expressed in prostate cells 1. Once activated, the androgen receptor stimulates the expression of specific genes that cause prostate cells to grow 2. Early in their development, prostate cancers need relatively high levels of androgens to grow. Such prostate cancers are referred to as androgen dependent or androgen sensitive because treatments that decrease androgen levels or block androgen activity can inhibit their growth. Most prostate cancers eventually become " castration resistant ," which means that they can continue to grow even when androgen levels in the body are extremely low or undetectable. Hormone therapy for prostate cancer —also called androgen suppression therapy or androgen deprivation therapy —can block the production and use of androgens 3. Currently available treatments can:. Treatments that reduce androgen production by the testicles are the most commonly used hormone therapies for prostate cancer. Normally, when androgen levels in the body are low, LHRH stimulates the pituitary gland to produce luteinizing hormone , which in turn stimulates the production of androgens by the testicles. However, the continued presence of high levels of LHRH agonists actually causes the pituitary gland to stop producing luteinizing hormone, which prevents testosterone from being produced. Treatment with an LHRH agonist is called medical castration sometimes called chemical castration because it uses drugs to lower androgen levels in the body to the same extent as surgical castration orchiectomy. But, unlike orchiectomy, the effects of these drugs on androgen production are reversible. Once treatment is stopped, androgen production usually resumes. LHRH agonists are...

Prepared by Harvard Health Publications' editors, this page report describes the causes and treatment of prostate diseases and provides practical advice for coping with troubling side effects. Get weekly health information and advice from the experts at Harvard Medical School. Learn more about this site in a welcome video from Dr. Marc Garnick, editor in chief. Androgens, the family of male sex hormones that includes testosterone, function as a fuel for growth — a quality that explains their central role in both normal development and prostate cancer. In adolescent boys, androgens not only trigger sexual development, but also contribute to a deeper voice, a beard, and increased muscle strength and bone mass. When prostate cancer develops, however, this androgen fuel contributes to tumor growth and progression. Androgen-deprivation therapy, more commonly known as hormone therapy, is one of the most powerful weapons in the fight against prostate cancer because it significantly reduces the fuel supply that is feeding malignant growth. First developed in the s, based on studies by Dr. Charles Huggins and other researchers at the University of Chicago, hormone therapy produced such dramatic early results that investigators thought they had found a way to cure prostate cancer. Unfortunately, long-term clinical trials later showed what we now know to be the case: Eventually prostate cancer becomes resistant to androgen-deprivation therapy and progresses. Eventually, these resistant prostate cancer cells multiply and the disease advances. In fact, one of my patients has now been on some type of hormone therapy for nearly 16 years. Once reserved solely as a treatment for metastatic prostate cancer, hormone therapy is now also used in a variety of other ways. And medication options — in terms of both the number of drugs available and choices about the timing and duration of therapy — have also evolved and improved. This article serves as a basic primer about hormone therapy for prostate cancer. It explains when to consider hormone therapy, what your options are in terms of drugs or combinations of drugs, and what you should know about side effects. Finally, it explores several controversies currently being debated...

Edited by Patricia K. Benign prostatic hyperplasia BPH is a pathologic proliferation of prostatic glandular and stromal tissues; a variety of growth factors and inflammatory processes are inculpated in its pathogenesis. Previously we showed that potent synthetic antagonists of GHRH strongly inhibit the growth of diverse experimental human tumors including prostate cancer by suppressing various tumoral growth factors. Reduction of prostate weights was observed after 6 wk of treatment with GHRH antagonists: In turn, GH stimulates the production of insulin-like growth factor 1 IGF1 , a major anabolic growth factor and a potent mitogen for many cancers 2. GHRH and its pituitary-type receptor as well as its truncated receptor splice variants SV are expressed in various normal human tissues including prostate, kidney, lung, and liver 3 and on many human cancer cell lines and tumors 1. To develop therapies for cancer, our laboratory has synthesized GHRH antagonists with high antiproliferative activity in numerous experimental cancer models 1. The inhibitory effect of these analogs is exerted in part by indirect endocrine mechanisms through the suppression of GHRH-evoked release of GH from the pituitary, which in turn results in the inhibition of the hepatic production of IGF1 7. Recent studies also indicate that GHRH antagonists reduce generation of reactive oxygen species 8 , which cause damage to prostatic stroma and epithelium 9. Benign prostatic hyperplasia BPH is a progressive hyperplasia of prostatic glandular and stromal tissues. Currently, there is no completely effective treatment for BPH. In some patients surgery, mostly transurethral resection of the prostate, is the only effective intervention New therapies are clearly needed. Despite the enormous burden of BPH on public health, its pathogenesis is incompletely understood. A model of BPH in male rats can be produced by repeated injections of testosterone This model has been adapted for...

What man is not aware that internal secretions of estrogen are the "magical" essence of a woman's behavioral mystique? Conversely, women have learned that most of the bad and some of the good that men do can be explained by their levels of testosterone. Estrogen and testosterone are steroid hormones, and levels of these chemicals in the body define sexuality and regulate behavior. The human body also manufactures protein hormones. Adrenaline is a protein hormone, and so is insulin. Human growth hormone is also a protein. These hormones are responsible for metabolic functioning and "internal housekeeping. This hormone was much more powerful than human growth hormone. The resemblance ends when the potency of IGF-I is compared to insulin. IGF-I is times more potent than insulin. Eat pizza with mozzarella or Parmesan on pasta, ice cream or yogurt, and you deliver this hormone to your body. This prestigious journal is read by over , scientists every week. On January 23rd, vol. Oxford researchers determined that a diet without meat or dairy products could reduce the risk of contracting prostate cancer. The authors cite earlier studies suggesting that high levels of IGF-I play a key role in causing prostate cancer. Physician and founder Neil Barnard writes this must-read column: Please copy today's column and give it to any friend, relative, or associate who is a candidate for, or has been diagnosed with, prostate cancer.
