The fertilizing effects of MACA are undeniable; it contains a biochemical substance that stimulates the brain and the reproductive organs. Many have proven that MACA favors fertility and helps to regulate the menstrual cycle. Castro De Leon (1998) affirms that it all seems to indicate that MACA is an excellent invigorator, which can perform real miracles in people afflicted with problems related to frigidness, sterility, or all these deficiencies together. As a result, many women that regularly consume the MACA root have returned to being very fertile. 

Some of the work and investigations indicate the following results: 

REA and PULGAL VIDAL (1980), the MACA root contains properties that help with fertility, since positive results were obtained when given to sterile animals. According to REA, the protein rich content of the MACA root make it superior to roots cultivated 2500 meters above sea level. (Ibis, pg. 105)

HELMAN M. (1985) states that reproductive function of MACA is well known. 

LEON (1974) other than its nutritional values, MACA increases reproduction in animals and humans, the colonial Spaniards knew this even before today’s scientific results. (Ibis, pg 105)


FERTILIZING ACTIONS OF MACA: Dr. Freddy Madrid Giranda; Dr. Gloria Chacon de Popovici, Universidad Mayor de San Marcos, MACA nutritional course II, December 3-5, 1998.

    dog3.jpgCASE #1: ‘Silvi’, a 12 kg Cocker Spaniel, 1.5 years old. Ever since Silvi was born, she never went into heat. She was given 2 grams of MACA with her food and after 3 months she went into heat. She was mounted manually as shown in the photograph. Silva was impregnated and went through normal labor giving birth to 4 healthy puppies. One of the puppies was given to the owner of the male.  

   dog2.jpgCASE #2: ‘Yosi’, a 30 kg German Sheppard, 2 years old. Ever since she was born, Yosi was never in heat. She was given 5 grams of MACA with her food for 77 days. She went into heat and was mounted manually. She was impregnated, went through a normal labor and gave birth to 9 puppies, 2 died during the process and 7 survived, 2 females and 5 males, all healthy.

   dog1.jpgCASE #3: ‘Pepita de Altamira’, a 23 kg Basset Hound, 4.5 years old. Ever since her birth, Pepita never went into heat. She was given 3.5 grams of MACA for 58 days. She went into heat and was mounted manually. She was impregnated, went though labor and had a cesarean. She gave birth to 9 puppies, 1 died during the process and 8 survived, 4 males and 4 females, all healthy.  

Studies show that the use of MACA in animals is not only limited to dogs, as discussed in her book “MACA, the Medicinal and Nutritional Plant from Peru”, by Dr. Lida Obregon Vilches, 1st edition, 1988; Lima, Peru.

“The Zoological Faculty from the University of Central Peru, Huancayo, in 1995 presented the following thesis: ‘Effects of MACA  in the presentation of heat in cows in the ‘Chaera Valdivia’ stable in Matahuasi-Concepcion, the results were overwhelming as to the procreation of the animals. 

There is an interesting investigation involving the use of MACA and the reproduction of sheep. In 1961, Yauri and Valerion studied the volume, ph, concentration of the seminal fluid, motility of the spermatozoids, and used this information to determine the effects of MACA in sheep. They used 12 sheep around five years of age and administered 80 grams of MACA orally in 300cc for the space of 15 days.

MACA did have a significant effect on the amount of semen ejaculated, concentration of seminal fluid and spermatozoid motility. (Tony Matos Tovar, 1995). Therefore, the use of MACA in sheep increased the production of semen and the activity of the spermatozoids.    

In 1961, Dr. Chacon de Popovici performed studies in rats and frogs as part of her thesis to obtain her bachelors degree in Biological Sciences: “Phyto-chemical study of the Lepidium Meyenii Walp.” The purpose of her research was to investigate the frequency of procreation and the effects of MACA on the reproductive organs of these animals. Her research showed that MACA had vigorous effects on the maturation of the follicles (structure in the ovary that produces the egg), and increased the number of spermatozoids in males. Studies performed with animals have always yielded great results. According to Dr. Chacon, the fertilizing effects of MACA have been scientifically proven.
