The Maca Root, Fertility and Libido

Fertility improvement has been the main benefit attributed to the maca root since the 16th century, and it is believed that is one of the main reasons for the increase of population in the settlements located in the highlands of Peru.

There was an interest years ago in demonstrating the fertile effects of the maca in humans and lab rats. Nowadays, we are certain about the many benefits of maca; this is due to several studies that this root has been subject to, which results have verified that this food has similar components and reactions as testosterone over biological activities.


  • The maca has alkaloids that can act as a stimulator over the pituitary gland in charge of the acceleration of the sexual arousal impulse in both feminine and masculine reproductive organs.
  • A clear stimulation of the maturation of follicles can also be observed in both male and female lab rats.
  • An increase in the sperm can also be seen in the seminiferous tubules of the male rats.


  • Over 200 sterols have been isolated from a majority of vegetable food, the most abundant in the maca are βeta-sitosterol, campesterol and stigmasterol.
  • Sterols found in the maca improve the possibilities of fertility in men and women, in addition to the properties that help against high cholesterol levels, as an anti-inflammatory and antioxidant.
  • They act in the hypothalamic-pituitary axis, stimulating the secretion of reproductive system hormones in both men and women, which means that maca, without any direct hormonal contribution, acts on the body by supporting the endocrine system for the production of hormones.


  • The effects of pure essence extract of maca over lab rats show an increase in the spermatogenesis, follicle maturation, a rise in offspring and improvement of the metering by balancing the testosterone production.
  • It augments their quality given that it reduces damage to the sperm cells. This is due to the antioxidant effect that Vitamin C has, which protects the sperm cells from the oxidative attack of free radicals.
  • On the other hand, it also has a positive effect on sexual potency, stamina and performance.
    It corrects erectile dysfunction which may be due to the presence and effect of Arginine, an amino acid that promotes blood circulation in the penis.
  • The effects of dry, ground maca in guinea pigs show an increase in their fertility and progeny.
    Sheep fed with 80 grams of maca during 15 days showed an increase in sperm volume and enhanced the sperm concentration and mobility.
  • In the study of Gonzales, a 1500 mg a day dose of Lepidium meyenii was administered to six men and a dose of 3000 mg a day was administered to three other men over four months. At the end of this period a seminal exam was performed in accordance with the World Health Organization (WHO); a significant difference was found in:
    • Seminal volume increased from 2.23 ml to 2.91 ml,
    • The sperm count per ejaculation from 140.95 x 106/ml to 259.29 x 106/ml,
    • The mobile sperm count went from 87.72 × 106 / ml to 183.16 × 106 / ml respectively.
