âEstradiol plays an important role in libido in men taking testosterone supplementation,â Dr. Ramasamy said, adding that this finding is similar to what was identified in a recently published study by Joel S. Finkelstein, MD, and collaborators at Massachusetts General Hospital in Boston.
While its importance is normally attributed to women, estrogen in men plays an important role. As teenagers, men have high levels of testosterone and low levels of estrogen. As they age, testosterone levels in men decrease while their estrogen levels increase. Not surprisingly, high levels of estrogen in men usually correspond to low levels of testosterone.
