What is Maca Root?

Maca is an exotic root traditionally taken to improve sexuality and fertility. Oral administration significantly improved the sexual behavior in male rats and mice. More recently, it has been demonstrated that Maca improves spermatogenesis in male rats. Maca root is rich in essential minerals, especially Selenium, Linolenic, Palmitic and Oleic Acids, and Polysaccharides.

How does it work?

Maca is an adaptogen, which means it helps the body adapt to stress, and helps to return a dysfunctioning system back to normal balance. Maca supplementation showed increased seminal volume, sperm count per ejaculum, motile sperm count and sperm motility.

Where does it come from?

The root of this Peruvian plant grows in the central Andean region of Peru between 4,000 and 4,500 m altitude, mainly in Junin and Cerro de Pasco.

Safety / Side Effects

There have been no reported side effects with taking Maca root. Its long-term use as a food source in Peru suggests that it’s safe.

Studies Involving Sperm

Nine men received tablets composed of a Maca root formula (1,500 or 3,000 mg/day) for four months.  Seminal analysis was performed according to guidelines of the World Health Organization.  Serum Luteinizing Hormone (LH), Follicale Stimulation Hormone (FSH), Prolactin (PRL), Testosterone (T), and Estradiol (Es) were measured before the treatment.  Treatment with the supplement resulted in increased seminal volume, sperm count per ejaculum, motile sperm count, and sperm motility.

Interactions

At this time, there are no known interactions between Maca root and other therapies.
