The scarcity testostéroneAlors low rate of symptomatic that almost a quarter of American men suffer from low testosterone levels, only about 5.6% experience symptoms of the condition known in medical terms as androgen deficiency. In a study by Dr. Andre Araujo and colleagues at the New England Research Institutes, it was found that all men with low testosterone exposure or symptoms of experience. There are fewer men with symptomatic androgen deficiency that there are men with testosterone levels bas.Comme most important sex hormone produced in the male body, testosterone or androgen is the hormone that is mainly responsible for production and maintaining the typical adult male attributes. At puberty, testosterone stimulates the physical changes that characterize the adult male as the enlargement of the penis and testes, growth of facial and pubic, deepening of the voice, increased muscle mass and strength, and growth in height. Throughout adult life, testosterone helps maintain sex drive, sperm production, hair patterns in humans, muscle mass and the mass of a man osseuse.Les testosterone levels decline naturally with age. However, there is no dramatic drop in sex hormones of a man as there are for women at the time of ménopause.Symptômes androgen deficiency include: · Loss of libido Erectile dysfunction · · Low count · Reduced sperm fertility · Increased breast size bone loss or fracture · · Two or more of what endocrinologists call “nonspecific symptoms”: sleep disturbance, depressed mood, lethargy and diminished physical performance .The men who suffer from sexual health problems such men as symptomatic androgen deficiency receive treatment if they have no cons-indications such as prostate or breast cancer. But the guidelines of the Endocrine Society treatment state that declines associated with aging without symptoms and testosterone should not be traités.Selon Dr. Robert Davis, a professor of urology at the University of Rochester in New York, men with a waist circumference over 40 inches, high blood pressure, and insulin resistance marks, and the so-called metabolic syndrome are at high risk of androgen deficiency. “These men have an incredibly high rate of androgen deficiency and to treat them with testosterone may correct their metabolic syndrome because they may be able to burn energy better with more muscle. Testosterone replacement may allow these men to avoid some of the consequences of metabolic syndrome such as coronary heart disease, “said Davis. An androgen deficiency is a male sexual health problem under diagnosed and under-treated.” One of the myths is that supplements Testosterone will cause cancer, “he said. Prostate cancer often regresses when testosterone is removed, but there is very little evidence to support the theory that normal testosterone levels increases the risk of cancer.En regarding men who have low testosterone levels, but no symptoms, there is a possibility of loss of bone density. According to Dr. Sol Jacobs, an endocrinologist and assistant professor of medicine at Emory University in Atlanta, “Even if you have a man who says, ‘I feel good and I do not want testosterone treatment,” at least measure her bone density. But usually the scenario is the patient is symptomatic and wants treatment “.However, the question of when to provide a replacement of the patient Testosterone is highly controversial. Even the Endocrine Society panel of experts disagree on the exact levels of testosterone at which doctors should offer testosterone replacement therapy.
