The key to masculinity and vitality is the human growth hormone that separates the boys from the men. It plays a vital role in the creation of muscle mass and strong bones. It contributes to deep voice and even sex drive. Low testosterone in men is known as hypogonadism. As a product of a modern world made for convenience the male body does not go through nearly as much rigorous activity. The lack of daily exercise contributes to the decrease in male testosterone. It can hit as early as the mid 20s and steadily decrease each subsequent year.
In the cardiovascular trial, researchers assessed coronary artery plaque buildup by CT angiography. That assessment showed more plaque buildup in men treated with testosterone than in men treated with placebo. Nonetheless, in all 788 men in the TTrials, the number of major adverse cardiovascular events was similar in the men treated with testosterone as in the men treated with placebo. However, Snyder added, "treating 788 men for one year is far too few to draw conclusions about the clinical significance of the increase in coronary artery plaque volume and the cardiovascular risk of testosterone treatment."
Television, the internet, and magazine ads all target men with products that address the drop in testosterone that occurs with age, but despite being classified as a male hormone, testosterone is also produced by women. While it’s true that men produce far more testosterone than women do, during the early reproductive years, women have 10 times more testosterone than estrogen within the body, leading experts to believe that it’s really testosterone loss that results in many of the symptoms women go through in midlife, such as low libido, fatigue, low muscle tone, weight gain, and loss of mental focus. 1
