Maca and Fertility: Scientific Studies & Historical Evidence

Infertility is a growing challenge in the modern world, impacting an increasing number of couples. With medicine often unable to determine the cause in up to 30% of cases, many turn to in vitro fertilization (IVF). While IVF is an option, a time-honored natural solution exists: Peruvian Maca.

We've seen hundreds of couples worldwide, including dozens who failed multiple IVF attempts, find success with our Nuestra Maca products. Is this a coincidence? The history and science say no.


A Heritage of Potency and Fertility

In Peru, Maca has been synonymous with fertility for millennia, predating the Inca civilization.

  •     • The Moche Civilization (100–700 AD): The Moche, who lived on the Peruvian coast, left behind numerous clay figures emphasizing the fertility, potency, and sexual desire of both men and women. The frequent traces of Maca found in their settlements suggest it was a favorite and daily food source.

  •     • A Continuous Tradition: Maca remained a symbol of male potency and female fertility throughout the Inca civilization, the Spanish colonial era, and continues to hold this significance today in Peru and globally.


The Scientific Proof Behind Maca

Given its long history, universities in Peru and around the world have conducted numerous studies to confirm Maca's impact on fertility. Peru's esteemed Cayetano Heredia University is a leader in this research.

Key Findings from Academic Research:

  •     • Mechanism of Action: Studies have confirmed a positive effect on fertility in rats. Researchers isolated four alkaloids (Macaenes) responsible for this effect. These compounds were found to significantly improve egg maturation in females and increase sperm count and motility in males.

  •     • The Hypothalamic-Pituitary Axis: The pioneering work of Dr. Chacon concluded that Macaene activity influences the hypothalamic-pituitary axis, which explains its ability to induce positive changes in both sexes. Maca was also found to affect the adrenal axis.

  •     • Aphrodisiac Properties: The aphrodisiac qualities are often attributed to biologically active aromatic isothiocyanates and glucosinolates present in the root.

  •     • Specific Studies (Gonzales, 2001): A study using black Maca extract in men concluded that sperm levels and motility were significantly improved after just 15 days of consumption.

  •     • Red and Black Maca Benefits (Gonzales, 2014): Extracts of red and black Maca were found to:

  •           • Enhance sexual desire and energy.

  •           • Improve fertility of both partners.

  •           • Reduce the embryo mortality rate.

  •           • Lift mood, alleviate depression and anxiety, and improve memory.


    • Maca and IVF Success: Our Results

      The scientific evidence clearly shows that Maca, particularly red Maca, reduces the rate of embryo mortality. Building on this evidence, our five years of experience with Nuestra Maca have yielded remarkable results:

      •    • Dozens of couples who had failed multiple IVF attempts succeeded on their first try with the help of our products.

      •     For natural conception, the occurrence of fetal loss is minimized.

      •    • Our success rate for conceiving with our products is more than 60%.

      Maca is not a coincidence; it is a proven natural support for fertility.


      Abstract: Peruvian maca was used for medicinal purposes as a source of energy, vitality, and endurance. In addition, it was used as an aphrodisiac and tonic for postmenopausal problems (Leon, 1964). Studies on rats have confirmed a positive effect on fertility. Four alkaloids (Macaenes) isolated from Maca roots at the University of San Marcos in Lima are responsible for this effect (Chacon, 1990). These alkaloids were administered to male and female rats either purified or combined. A significant improvement in egg maturation was observed in females that received any type of preparation. Also, in both preparations, a significant increase in the amount of sperm as well as an increase in sperm motility was observed in males. Chacon concluded that Macaenes activity affects the hypothalamic-pituitary axis, which explains why Maca has the ability to induce changes in both sexes. Furthermore, Chacon found that maca has the ability to affect the adrenal axis. 

      The aphrodisiac properties of maca root can be attributed to the influence of biologically active aromatic isothiocyanates (Johns, 1981). Johns explains the positive effect on fertility by the influence of glucosinolates present in maca root. There are various scientific studies that have shown great results on the fertility of both sexes, enhancing sexual desire and energy (Canales y col, 2000; Zheng y col, 2000; Gonzales y col, 2001). The first study, where black maca extract is used in men, concluded that sperm levels and motility were significantly improved after 15 days of consumption. The article was published in the Asian Journal of Andrology in September 2001 (Gonzales y col., 2001).
