Testosterone is the main male sex hormone, but it’s important for women as well, in smaller amounts. Testosterone helps maintain muscle mass and bone strength, enhances sex drive and helps with overall sense of well-being and zest for life. Overall, lower testosterone levels are being found among men in the general population. In men, testosterone levels decline about 10% every decade, but sometimes the levels drop sooner or more severe than they should. Environmental factors play a large role and low testosterone in men is commonly overlooked. Some of the warning signs of low testosterone levels include infertility, decreased muscle mass, depression, weight gain, decreased sex drive, and fatigue. There are many natural approaches to balancing hormone levels and supporting men and women in being healthy.
