Testosterone is the hormone that makes men—men. Testosterone is considered as the most essential of all sex hormones. It is a steroidal hormone that is primarily secreted by the testes in males and in ovaries in females. Females also have small amounts of this hormone in their system because it is a precursor to estrogen. In men, it is responsible for bone and muscle development. As stated, testosterone is essential in male sexual health because it stimulates spermatogenesis and influences the development of male secondary characteristics like facial hair and deep voices. This hormone is also responsible for mental sharpness and sex drive. Some medical reports suggest that testosterone is important in the development of self-confidence and social success.
Other functions and roles of testosterone may include the following:
Promotes muscle strength and endurance
Increases libido
Increases bone density
Decreased fat in tissues
Promote overall health and well being.
Overproduction of testosterone in males may lead to aggressive puberty in men and amenorrhea (absence of menstrual period) in women. Recent medical studies suggest that testosterone levels in the United States are lower today than they were several years ago. Some of the possible factors that are responsible for this decline are explained in this article.
Excess weight and obesity
One possible explanation for testosterone decline is: men are more overweight than ever. Medical studies suggest that obesity is a significant predictor of low testosterone. These studies add that gaining ten percent in one's appropriate Body Mass Index (BMI) may lead to decreased testosterone levels by about ten percent. Because of this, fat or over weight individuals may have up to 25 percent less total testosterone than their fit counterparts.
Smoking
Cigarette smoking may damage the cells in the testes—male reproductive organs located in the scrotum which produces sperm and testosterone. Smoking-induced damage may hamper testosterone production and cause problems in male sexual health. It may also interfere with the body's efficiency and effectiveness in building muscles.
High blood pressure
In the long run, high blood pressure may damage the lining of the blood vessels and cause atherosclerosis, or hardening of the blood vessels. Because of this development, less blood which carries oxygen and nutrients flow to the penis. For a lot of men, decreased blood flow may cause difficulties in achieving and maintaining erections. High blood pressure may also interfere with ejaculation and reduce libido. Many medications used to treat high blood pressure may also bring similar adverse effects.
Making lifestyle changes are essential in maintaining the right testosterone levels and overall health. A man's testosterone levels will have a decline once he reaches the age of 40. But maintaining a healthy lifestyle and nutritious diets may slowdown this decline and maintain optimum sexual health. If these things fail there are medical methods available that may be used to improve one's testosterone levels. Undergoing testosterone replacement therapy and using testosterone supplements may improve one's testosterone levels. Individuals who want to engage in these methods should seek the approval of medical professionals.
