Maca root is everywhere in fertility shopping: powders, capsules, “his and hers” bundles and smoothie boosters. Couples trying to conceive (TTC) often ask the same three questions: does maca help fertility, is it for men or women, and is it worth buying? Here’s a practical, evidence-first buyer’s guide.
This is educational, not medical advice. For the full picture on supplements for both partners, see fertility supplements for couples.
1. What maca is
Maca (Lepidium meyenii) is a root vegetable grown in the high Andes of Peru, traditionally eaten cooked or dried. In stores you’ll see yellow, red and black maca, plus “gelatinized” maca, which has been heat-processed to remove starch and is often easier on the stomach.
2. What the research shows — men vs women
| Men | Women | |
|---|---|---|
| Main topics studied | Libido and semen parameters | Libido, mood and menopause symptoms |
| Study size | Mostly small studies (often dozens of men or fewer) | Small studies, few in women actively TTC |
| Doses used | Commonly 1.5–3 g of maca a day in early studies | Varies by study |
| Pregnancy rates | No large, high-quality trials show that maca increases the chance of pregnancy. | |
Some small studies in men reported changes in semen measures and libido, while others found no clear difference. Systematic reviews describe the evidence as limited and mixed. That makes maca a reasonable “nice-to-have” for some couples — not a replacement for a semen analysis, a prenatal or a doctor’s evaluation.
3. Who maca may suit — and who should ask first
- May suit: couples who want a food-based add-on for energy or libido, who have already covered the basics (prenatal for her, a targeted male formula for him) and have their doctor’s OK.
- Ask first: anyone with a thyroid condition — maca is a cruciferous plant that contains glucosinolates; your doctor can tell you whether it fits. See thyroid health and conception.
- Ask first: anyone with a hormone-sensitive condition, or on fertility medicines or IVF.
- Stop: at a positive pregnancy test, unless your OB says otherwise — there isn’t enough safety data for pregnancy or breastfeeding.
For him, sperm take roughly 72–90 days to develop, so any change you make shows up in a repeat semen analysis about 3 months later. Read what 90 days can and can’t do.
4. Maca vs a targeted fertility formula
| Maca powder/capsule | Targeted TTC formula | |
|---|---|---|
| What you get | One root, usually no vitamins or minerals | A combination designed around TTC wellness, listed per serving |
| Best use | Optional add-on | Core of a plan, alongside a prenatal (for her) |
| Things to check | Color/type, gelatinized or raw, grams per serving, heavy-metal testing | Full label, overlap with your prenatal, how to take it |
If budget is tight, most couples get more from covering the basics for both partners first and adding maca later. Our budget buying order shows what to buy first.
5. Buying maca: 5 quick checks
- Grams per serving clearly listed — not hidden in a proprietary blend.
- Gelatinized vs raw: gelatinized is often easier to digest.
- Third-party testing for heavy metals and contaminants (USP, NSF or a published certificate of analysis). In Canada, look for an NPN.
- No overlap surprises: some “male fertility” blends already include maca — read the label before stacking. Our male label check helps.
- A review date: plan to check in with your doctor after about 3 months, with a repeat semen analysis for him if one was abnormal.

FAQ
Does maca help you get pregnant?
There are no large, high-quality trials showing that maca increases the chance of pregnancy. Small studies looked at libido and semen measures with mixed results.
Is maca better for men or women?
Most fertility-related maca research is in men, focused on libido and semen measures. Studies in women mostly look at libido, mood and menopause symptoms.
How long does maca take to work for sperm?
Sperm take roughly 72–90 days to develop, so any change would show up in a repeat semen analysis about 3 months later.
Is maca safe if I have a thyroid condition?
Maca contains glucosinolates, like other cruciferous plants. Ask your doctor before using it if you have a thyroid condition.
Can we take maca with AGO Mom and AGO Dad?
Ask the AGO care team for the product labels and review them with your doctor or pharmacist so you know exactly what you’re combining.
Should I stop maca when I get a positive test?
Yes, pause and ask your OB. There isn’t enough safety data on maca during pregnancy or breastfeeding.
