Maca,
does it really help with Female desire and sexual function, including antidepressant-associated sexual dysfunction?

30-Second Summary
C
Evidence Grade C · 40 · Safety caution
Trials in women are small, key total scores were null in antidepressant-associated dysfunction, and only selected subgroup signals remain
What the
research shows
Evidence for maca in women is small and inconsistent across scales and subgroups, supporting C. In an analysis of 42 women with antidepressant-associated sexual dysfunction, changes in total ASEX and MGH-SFQ scores did not differ significantly from placebo. A crossover trial in 14 postmenopausal women showed signals only on selected psychological and sexual-function measures.
What the
ads claim
Marketing claims hormonal balance, immediate libido enhancement, or reversal of antidepressant side effects. Some marketed products combine maca with red clover, pomegranate, zinc, or vitamins, so their effects cannot be attributed to maca alone.

Useful facts when choosing a product

  • Maca powders, capsules, and combination products are sold in Korea as foods or imported products, with differences in origin, color phenotype, gelatinization, and extract ratio.
  • The female antidepressant-associated trial used 3.0 g/day of maca root for 12 weeks, and the postmenopausal crossover trial used 3.5 g/day.
  • Products combining red clover, pomegranate, zinc, or vitamins are not equivalent to single-ingredient maca trials.
  • Short-term use may cause gastrointestinal discomfort or headache, while safety evidence is insufficient in pregnancy, lactation, and hormone-sensitive conditions. Antidepressants should not be reduced or stopped without medical guidance.

What the research actually shows

The 2015 Dording trial randomized 45 women with remitted depression and SSRI- or SNRI-associated sexual dysfunction and analyzed 42 in a modified intention-to-treat population. After 12 weeks of maca at 3 g/day, changes in total ASEX and MGH-SFQ scores were not significantly different from placebo overall or within premenopausal and postmenopausal subgroups, although selected remission thresholds and item-level signals appeared. The 2008 Brooks crossover trial in 14 postmenopausal women reported that 3.5 g/day improved selected psychological and sexual-function measures on the Greene scale. A 2010 systematic review concluded that evidence for sexual function was limited; its predominantly male evidence was not transferred to this female claim.

02

Why this is classified as C (40)

Direct female trials prevent a D or ? rating, but the most relevant antidepressant-associated trial was null on between-group total scores and the postmenopausal trial enrolled only 14 participants. Only subgroup and item-level signals remain, supporting C with 41 points.

Counterpoint. A responsive subgroup among postmenopausal women or users of particular antidepressants cannot be excluded. Male libido, erectile, and sperm studies were not used for this verdict.

Rejudgment record. New verdict — Direct trials in women exist, but key total-score comparisons were null, the postmenopausal trial was extremely small, and scale-level findings conflicted, capping the rating at C

Sub-claim grades by effect

This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.

Effect (sub-claim)GradeBasis
Antidepressant-associated sexual dysfunction in womenCAmong 42 analyzed women, changes in total ASEX and MGH-SFQ scores did not differ significantly from placebo, while only selected remission and item-level signals appeared.
Desire and sexual function in postmenopausal womenCSelected signals appeared in a 14-person crossover trial and a very small subgroup of the antidepressant trial, but sample size and replication are inadequate.

Cross-check — Codex and Claude

This verdict was drafted by Codex through literature review and source-existence checks, cross-checked through blind grading and adversarial audit, and settled by reapplying the methodology boundary rules. Cases with split grades were resolved through rejudgment.
