  What Are the Benefits of Maca ...
  Maca root is touted for its benefits on the male libido and sexual function, reports WebMD. Although scientific evidence on these healing properties is far from conclusive, physicians may use it to treat hormone imbalances and fertility issues.
  Most of the support for maca root is anecdotal evidence passed down from generation to generation, reports WebMD. Scientific studies have not yet found conclusive evidence on its supposed libido-boosting properties in humans, but animal studies have found it to be an aphrodisiac. Dr. Adriane Fugh-Berman of Georgetown University Medical Center adds that the libido-boosting properties found in animal studies are only slight and often over-reported. Dr. Fugh-Berman also does not believe that maca root can directly cause sexual healing in humans, as there are social and psychological factors involved.
  There are other possible benefits of maca root other than improvement in libido, according to WebMD. Dr. Fugh-Berman reports strong evidence for the use of maca to improve sperm quality and fertility in specific men. Other physicians, such as Dr. Hyla Cass, use the root on a regular basis to treat hormone imbalances, in addition to libido issues and low fertility in both men and women. At the very least, maca root does not have negative health effects; it is a staple of Peruvian diet, and when used as a supplement, no significant side effects have ever been reported.
