Maca As Sexual
Enhancer
Maca's ability to help
restore libido for men and women is probably what it is
best known for. It is often described as an
aphrodisiac for both sexes because of its beneficial
effect on testosterone, progesterone and estrogen.
Therefore, it facilitates balance to the hormonal
changes of aging. In both sexes, it restores a healthy
functional status in which they experience a more active
libido.
While Maca is often
compared to the drug Viagra, it actually works very
differently in regards to its sexual effects. Viagra's
effects are circulatory whereas Maca's effects are
hormonal. As an energizer, Maca also helps to create
more vigor for sexual activity.
The first known published
human study on Maca's effect on libido and fertility in
men was conducted in Peru and published in the Asian
Journal of Andrology. Study data showed that Maca
increased sexual desire (libido) by 180% and increased
sperm count by 200%. Other benefits included increased
sperm mobility, increased DHEA levels, decreased anxiety
and stress, lower blood pressure and a general sense of
well-being.
In the prestigious medical
journal Urology (April 2000), scientists studied the
effects of Maca on rats with erectile disorders and low
testosterone levels. The Maca-fed group had an amazing
400% more copulation than the non Maca-fed group.
Rodents with low testosterone levels demonstrated a
significant increase in sexual activity, indicating a
possibility that men with low testosterone or erectile
dysfunction may experience improvement. In the studies,
the more Maca extract fed to the animals, the greater
their strength, libido and sexual
function.
The fertility powers of
Maca are highly prized by couples in the Peruvian
highlands. Men and women who fail to conceive a child
often eat Maca on a regular basis until conception
occurs. It is the actions of alkaloids and
isothiocyanate p-methyl benzyl that have been shown to
increase fertility in humans.
Maca alkaloids act on the
hypothalamus-pituitary axis and the adrenals. These
areas of the body produce hormones as well as energizing
substances like adrenaline. The end result is an
increase in energy, vitality, and virility. There are
numerous physicians' claims that Maca positively affects
ovarian function in women, and sperm count and quality
in men.
In studies with rats,
females given either Maca powder, or alkaloids isolated
from Maca root, showed significantly increased Graaf
follicles and other favorable endometrium
characteristics, which indicate a higher fertility
level. Male rats had significantly higher sperm
production and motility rates than in control groups.
The effects were measurable within 72 hours of dosing
the animals.
