Scientifically Validated Options to Increase Testosterone

First, what is low testosterone? Testosterone is the primary male sex hormone and a key anabolic steroid. It helps promote secondary sexual characteristics such as increased muscle and bone mass and the growth of body hair. It is also important in mood and energy levels. Men with low testosterone often have low libido, erectile dysfunction, osteoporosis, sleeping problems, depressed mood, and decreased physical performance. Some men only have one or two of these symptoms.
