Maca study reveals increase in sperm production and libido

Maca study reveals increase in sperm production and libido


Researchers at the Universidad Peruana Cayetano Heredia, in Lima, Peru, performed a 12-week double blind, placebo-controlled, randomized trial in which active treatment with different doses of maca was compared with placebo.

Men aged 21-56 years received 3 g of maca. An improvement in sexual desire was observed with maca at 8 weeks of treatment. Serum testosterone and estradiol levels were not different in men treated with maca than in those treated with placebo.

Another study was designed to determine the benefit of a 4-month oral treatment with tablets of maca on seminal analysis in adult normal men aged 24-44 years old.

Nine men received tablets of maca (1500 or 3000 mg/day) for 4 months. Serum luteinizing hormone, follicle stimulating hormone, prolactin, testosterone and estradiol levels were measured before and after treatment.

Treatment with maca resulted in increased seminal volume, sperm count per ejaculation, and sperm motility. Serum hormone levels were not altered.


Maca has become a popular fertility herb and for good reason. Studies have shown repeat success in improving sperm health, increase in sperm count and stronger motility. Maca also increases libido and sex drive.

What is maca?

Maca (Lepidium meyenii) is a root-like vegetable shaped like a turnip that grows at 12,000 feet and is only found in the high Andes of Peru and Ecuador. For more than two millennia, native Peruvians have used maca root as food and medicine, to promote endurance and improve energy, vitality, sexual virility and fertility.

How does the Maca work?

It is not known exactly why maca does what it does, but that is the case for most herbs. Maca has the ability to effect key hormones and functions of reproduction without containing hormones. It has a type of wisdom as to what hormones need balancing and which to increase/decrease. Men who use maca have been shown to have an increase in libido and healthy sperm.

How do you use Maca?

Maca comes in powder, capsule, tincture or pills. You can use the powder in a fertility smoothie or with juice.

Dosage: Recommended dosage is 1000-3000 mg a day. To obtain desired results maca needs to be taken regularly. There are no side effects from taking maca, remember it is a food.

      Hello Prince!
      Maca works to support hormonal balance in both men and women, egg and sperm health, and FSH levels in women, encourages a healthy libido in both men and women and normal endometrium health. It can be taken by both men and women, even if you do not have fertility issues per say. It may be supportive of you.

  7. i have a watery sperm.hw do i cure it?

    • Elizabeth Willett, MA, CH

      Musa ~ watery semen can be normal. There are theories and internet posts that having intercourse or masturbating too frequently can affect semen viscosity (how thick or thin semen is) in negative way, meaning you won’t be able to conceive, but no one has proven this to be true. Diet, level of hydration and possibly frequency of ejaculation can all play a role in the viscosity of a man’s semen and this too varies from man to man. I am not sure there anything wrong or is reason to seek a cure. You can however support sperm health if you need by trying Maca and any number of other suggestions made here…

    My husband sperm is not moving and I wanna know
    Maca is good for It to fix it Pls waiting for Ans

    • Hi Mj,

      Typically when there is a sperm count of 0, there is a hormone imbalance present. It may also be an issue of a physical abnormality that is blocking the sperm or causing no sperm production. It would be best to find out why his count is absent and get a full hormone panel run. If you do find out it is a hormone imbalance, maca may be a supportive option.

      Good Luck!

  19. hi,
    can diabetic people take MACA??


    • Hi Melanie,

      This would be a good question for your doctor. Maca may help the body to utilize glucose for energy rather than process it for fat storage. As for how it affects insulin levels, in my research I have not found specific studies or notes on that. It is always best to get the approval by your doctor before beginning any nutritional supplement. Your overall health in relation to the diabetes is a factor that must also be considered.

      Best Wishes,


  20. Good day, please i have had two miscarriages with follow up D and C to evacuate the uterus and when my period returned after 3 months it only flows for 1 day instead of 3 days. i have also been trying to conceive for the past 6 months without success. please what can i take. I am 38 years.

    thank you

    • Hi Ruth,

      I am so sorry for your losses! It can take some time for the body to regulate hormones after a miscarriage, be patient with yourself. Begin my supporting it through eating really well, exercising (walking and yoga are best), as well as focusing on supporting your uterine health. Both miscarriage and D&C can be very hard on your uterus, it may need some extra healing and support! You can learn more about Improving Uterine Health for Fertility at this link:

  21. Hi Dalene,

    I went to my OBGYN today and she recommended a prescription prenatal and DHA supplement. It also contains iron. I currently am taking a multivitamin with iron as well, but am going to switch to the prenatal. i am not pregnant yet, but she wanted me to start on prenatals before hand while we are trying. I take Maca and have for a little less than a month I am up to 2 pills as I am introducing it slow. I know Maca has iron in it, and I want to know if I can take the prenatal pills with iron and the Maca and not overdose on iron? Thanks!

    • Hi Samantha,

      Because iron is naturally occuring in Maca it should be fine to use with your prescription prenatal vitamin. Maca is a food, so is spinach, blackstrap molasses and elk meat; these all contain iron and are good sources of iron, but you would not avoid them because you are taking a multivitamin. I hope this makes sense.

      Best Wishes,
