Maca is a traditional plant common to the Andes Mountains and has been used for centuries to enhance fertility, improve sexual function, improve energy and more. Maca (aka Lepidium Peruvianum and Lepidium meyenii) belongs to the mustard family and is considered an adaptogen—helping us to adapt to a variety of stressors.
A systematic review was done to assess the clinical evidence for or against the efficacy of maca for sexual dysfunction. The review included only randomized clinical trials comparing maca to a placebo in men or women with sexual dysfunction. Four randomized controlled trials (RCT) met the inclusion criteria. Two of these trials suggested a positive effect of maca on sexual dysfunction or libido in menopausal women or adult. One other RCT did not show effect of maca in cyclists. The fourth study assessed the effects of maca in men with erectile dysfunction and did show significant effects.
While the evidence is limited, there does appear to be some effectiveness of maca in improving sexual function.
