Lepidium Meyenii (maca root)

Lepidium meyenii (AKA Maca root) is plant native to the high Andes of Peru around Lake Junin. It is grown for use as a root vegetable, a medicinal herb, and a supposed aphrodisiac. Its Spanish and Quechua names include maca-maca, maino, ayak chichira, and ayak willku.

Experimental evidence showed maca has nutritional, energizer, and fertility-enhancer properties, and it acts on sexual dysfunctions, osteoporosis, benign prostatic hyperplasia, memory and learning, and protects skin against ultraviolet radiation. Clinical trials showed efficacy on sexual dysfunctions as well as increasing sperm count and motility. Maca is a plant with great potential as an adaptogen and appears to be promising as a nutraceutical in the prevention of several diseases.

Testosterone controls sexual desire and spermatogenesis. However, the effect of maca on these physiological processes does not seem to be regulated by changes in serum testosterone or intratesticular testosterone levels. However, the mechanism is not yet known. Thus, further chemical and molecular research is required to identify which of the many components of maca accounts for the effects observed.

There is evidence that maca may improve sexual desire but is inconclusive an effect on erectile function. Small-scale clinical trials performed in men have suggested that maca extracts can improve semen quality, and boost libido. A small double-blind, randomized, parallel group dose-finding pilot study has shown that Maca root may alleviate SSRI-induced sexual dysfunction.

A 12-week randomized, double-blind, placebo-controlled study in 56 subjects found that Maca has no effect on sex hormone levels in men, including LH, FSH, prolactin, 17-OH progesterone, testosterone or estradiol.

A recent review states "Randomized clinical trials have shown that maca has favorable effects on energy and mood, may decrease anxiety and improve sexual desire. Maca has also been shown to improve sperm production, sperm motility, and semen volume."
