Testosterone Information And Role Of Them In Men-www.ggg258.com

Up to this day, many people are still confused as to what is testosterone. This is a hormone that plays an important role in a persons reproductive and sexual development. This is considered the most important of all male hormones. Women also produce the same hormone, but at significantly lower levels compared to men. Testosterone is included into a class of male hormones also known as androgens that are sometimes known as anabolic steroids, or simply, steroids. In men, testosterone is mainly produced in the testes, with a few amounts produced in the adrenal glands. Testosterone has a role in developing the male sex organ before the person is born. It also contributes to the development of secondary sex qualities during puberty including the deepened voice, increased penis size, and the growth of body as well as facial hair. Role of Testosterone The hormone plays a big role in a persons sex drive, muscle strength maintenance, and production of red blood cells. In other words, testosterone works in maintaining the overall health of a man. Among women, adrenal glands and ovaries produce testosterone. However, womens testosterone levels are only 1/10th or 1/20th compared to a mans. Before a boy is born, testosterone is already working to form his genitals. As he reaches puberty, testosterone works in developing a lot of male traits like deeper voice and facial and body hair. The same hormone also promotes sex drive and body mass. The peak of testosterone production is at late puberty or early 20s. Men having lower levels of testosterone may have erectile dysfunction. Also, they may lose their desire for sexual activities. Testosterone levels go up whenever a man is sexually stimulated, and it can drop after prolonged inactivity to sex. Testosterone and the Central Nervous System The human body has a system that is responsible for testosterone control. This sends messages through the hormones and other chemicals released to the bloodstream. The brains hypothalamus allows the pituitary gland to know how much testosterone is necessary, which the gland then sends to the mans testicles. Testosterone also contributes to the development of certain human behaviors including dominance and aggression. The hormone also helps in setting off competitiveness and strengthening self-esteem. As sexual activity can cause testosterone levels to rise, engaging in activities with competition involved can cause the hormones levels to either rise or fall. Low levels may cause poor self-esteem and little motivation. For a man, low levels of testosterone can also lower his ability to focus. It can also cause feelings of sadness and mild depression. Lack of energy and disturbances during sleep may also be caused by lower levels of such hormone. It should, however, be noted that the levels of testosterone is just one factor that can affect a persons personality traits. Testosterone Relationship to Skin and Hair As a man passes from his childhood and enters adulthood, his testosterone stimulates the growth of hair around his body such as his armpits, face and around his sexual organ. Some men also grow hair on their chest, legs and arms. When his testosterone levels shrink, he may also lose some body hair. Testosterone therapy is available for people with deficiency of such hormones, but they do come with side effects. These side effects include enlargement of breasts and acne. Testosterone patches can cause skin irritation for some. Topical testosterone gels are also available, but a person should take care when using it to avoid transferring hormones to another person through skin contact. Muscle, Bone and Fat in Relation to Testosterone Many factors are involved in developing a persons muscle mass and strength. Testosterone increases the level of neurotransmitters, encouraging growth of tissues. It also interacts with nuclear receptors located in DNA, causing protein synthesis. Testosterone increases growth hormone levels, making exercises more likely to build muscle mass. Besides building muscle mass, testosterone can also increase bone density and stimulate the production of more red blood cells. Men having low testosterone levels are more likely to suffer fractures and other bone-related injuries. Testosterone plays an important role in fat metabolism. This helps men burn fat more effectively. When a mans testosterone level drops, chances are, he will increase his body fat and weight. The Heart and the Circulatory System Testosterone hormones travel along the bodys bloodstream. To measure the bodys testosterone level, a blood test should be performed. Studies show that testosterone may also have good effects to the heart. However, some research that focus on investigating the hormones effect on blood pressure, cholesterol, and blood-clot breaking ability had different results. When it comes to testosterone therapy regarding the heart, studies gave conflicting results and other studies are still ongoing. Hormone therapy given though intramuscular injection can increase blood cell counts. Other side effects are also reported. Low Testosterone Causes and Effects As a man reaches the age of 30, his testosterone levels start to decline naturally. Other causes of low testosterone are infections, certain injuries or loss of the testicles. Radiation treatment can also decrease testosterone levels. Other disorders that can cause the decline of the hormone are chronic conditions like liver cirrhosis, recurring kidney failure, alcoholism, stress, and excess fats especially in the abdominal area. Certain changes in the body happen whenever the testosterone levels are low. These include increased body fat, decreased muscle mass, changes in the bodys cholesterol count, mild anemia, and brittle bones. How to Find Out if You have Low Testosterone The most accurate way to determine if you have low testosterone level is to have a doctor examine your blood. More than a few measurements should be undertaken to be sure if you have a deficiency. This is because the hormones levels tend to fluctuate many times a day, and a single measurement may not be as accurate. Some symptoms can be observed even if you havent check with your doctor. When you have fewer erections every morning, decreased muscle strength, irritability, and have low or no interest for sex, you are most probably low in testosterone. If you are one of those who are asking what is testosterone, then it is one of the most important hormones responsible for the overall well-being of the human body. 相关的主题文章:
