Maca stimulates sexual function in male mice
Male mice treated for 22 days with a lipidic extract of maca
(Lepidium meyenii)
demonstrated 2.9 to 4.1 times more mating behavior than mice in
an untreated control group, according to the results of a Chinese
study. The mice in the maca group showed a significant increase
in both mounting and copulatory behavior, compared with controls.
Two different maca preparations were tested, both standardized
to the fatty acids macaene and macamide. The researchers claim
that theirs is the first study to scientifically demonstrate an
aphrodisiac effect for maca. Zheng BL, He K, Hyungchan C, et
