Titain's Testosterone Testosterone is a male hormone made in the testes (in males). It is used primarily by men to increase muscle mass. Testosterone is also used in men to increase sexual arousal and/or libido, to enhance muscular strength and to reduce symptoms of aging. Some men use testosterone to enhance muscle tone, androgenic side effects such as the growth of facial hair and beard and a greater level of physical activity. In men, testosterone is an important component of the male hormone system. A drop in testosterone levels can cause depression, poor mood, and an increased risk of developing some forms of cancer. Testicular (testis) health is of great importance to males. Testosterone is a major hormone that affects both muscle and bone development, muscle function, and overall strength and endurance. It is essential to the development of male secondary sex characteristics, which include facial hair and beard growth, muscle tone and strength, and an increase in muscle mass. Men with a low or undetectable level of testosterone have no symptoms of erectile dysfunction. However, in men with low levels of testosterone, erectile dysfunction is common, and the condition has been associated with a variety of medical problems, including prostate cancer.
Many people believe that increasing their testosterone levels will improve their sex life and reduce symptoms of depression.
