Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Maca (Lepidium meyenii) is a root vegetable native to the Andes mountains and has a long history of use in traditional Peruvian medicine as a tonic for energy, stamina, and fertility. Traditionally, maca has been consumed to enhance libido and improve reproductive health in both men and women. The belief that maca supports the testosterone body system is largely based on historic and anecdotal use rather than robust scientific evidence.

Modern scientific studies investigating maca’s effects on testosterone levels in healthy men have generally found no significant impact on serum testosterone concentrations. Several clinical trials, including randomized controlled studies, have shown that while maca supplementation may improve self-reported sexual desire and function, it does not appear to directly raise testosterone levels. A 2010 systematic review concluded that the evidence for maca’s effect on sexual function is limited and the mechanisms are not fully understood, with no clear link to increased testosterone production.

In summary, maca’s use to support the testosterone body system is primarily justified by traditional use and folklore. Scientific studies do not currently validate a significant effect on testosterone levels, though there may be other benefits related to sexual health and well-being. Therefore, the evidence rating for maca’s impact on testosterone is moderate for tradition but low for scientific validation.
