Friday May 23, 2013 (foodconsumer.org) -- A study published in the Feb 2009 issue of Andrologia suggests taking Lepidium meyenii (Maca) extract when as a dietary supplement can significantly enhance sexual performance in men with mild erectile dysfunction.

T. Zenico and colleagues conducted the clinical trial and found the score of the International Index of Erectile Function (IIEF-5) was significantly improved among men after taking the Maca root extract for 12 weeks.

For the trial, 50 Caucasian men suffering mild erectile dysfunction were treated either with 2400 mg of Maca dry extract or placebo for 12 weeks. The score of IIEF-5 and the Satisfaction Profile were determined for each participant before and after intervention.

Men in both arms of intervention experienced a significant improvement in the IIEF-5 score while only those taking Maca extract experienced a more significant increase than those treated with placebo.

Also significantly improved in both arms was psychological performance-related SAT-P score. But only Maca supplementation improved this score even more significantly.

Also only Maca-treated patients significantly improved physical and social performance-related SAT-P score, compared with the baseline. 

The researchers concluded "Maca supplementation on subjective perception of general and sexual well-being in adult patients with mild ED "erectile dysfunction)".

Lepidium meyenii (Maca) is a member of the brassica family used as an aphrodisiac in some regions. The aphrodisiac properties of maca root may be due at least in part to a compound called p-methoxybenzyl isothiocyanate.

Other ingredients or herbs or herbal preparations that may help enhance male sexual performance include yohimbe, Siberian ginseng, tribulus terrestris, ginkgo biloba, DHEAm, oat straw, and arginine which are commonly used in male performance enhancement products. (David Liu)
