Maca has been scientifically researched for the use of increasing fertility since 1961 and has been shown to contain specific compounds called glucosinolates which directly can affect fertility for both men and women. These alkaloids are responsible for maca’s ability to support hormonal balance.
In women, maca works by controlling estrogen in the body. Estrogen levels that are high or low at the wrong time can keep a woman from becoming pregnant or keep her from carrying to term. Excess estrogen levels also cause progesterone levels to become too low. Taking maca may help to increase the progesterone levels which are essential to carrying a healthy pregnancy.
Estrogen in men produces erectile dysfunction or lack of libido, low sperm count, and lowered production of seminal fluid. Studies have shown that men who use maca may experience an increased libido and an increase in sperm health.
Maca is a beneficial herb that has been used for thousands of years and consumed everyday as a food and medicine by the Peruvians. Based on its long history of use as a food it appears to be very safe. Toxicity studies (conducted at Product Safety Labs of East Brunswick, N.J.) showed absolutely no toxicity and no adverse pharmacological effects. - http://natural-fertility-info.com/maca
