Does Ashwagandha Make Women Horny?

A small but growing body of clinical evidence suggests ashwagandha can improve several aspects of sexual function in women, including arousal, lubrication, orgasm frequency, and overall satisfaction. The most-cited trial on the topic is a pilot study of 50 women that found statistically significant improvements across all of those measures compared to placebo. That said, the research base is still thin, and the mechanism likely has more to do with lowering stress hormones than with any direct aphrodisiac effect, which makes the picture more interesting and more complicated than a simple yes or no.

What the Women-Specific Trial Found

The study most directly relevant to this question was a randomized, double-blind, placebo-controlled pilot trial that gave 50 women a standardized ashwagandha root extract or a placebo for eight weeks. The researchers tracked sexual function using a validated questionnaire that scores arousal, lubrication, orgasm, satisfaction, and pain, along with a distress scale and a count of total sexual encounters. By the end of the eight weeks, the ashwagandha group showed significant improvements over placebo in arousal, lubrication, orgasm, satisfaction, overall sexual function, sexual distress, and the number of successful sexual encounters.¹

Those results look impressive on paper, but this was a pilot study with just 50 participants. It has been cited widely and sometimes presented as definitive proof, but the researchers themselves called it a pilot, meaning it was designed to test whether the idea was worth pursuing in a larger trial. The effect was real within that group, but it needs replication at a much bigger scale before anyone can call the question settled.

The Stress Connection

The most likely explanation for how ashwagandha improves sexual function in women is indirect: it lowers cortisol, the body’s primary stress hormone, and stress is one of the biggest libido killers. A systematic review and meta-analysis pooling data from 23 randomized controlled trials found that ashwagandha significantly reduced cortisol levels and increased serotonin, a neurotransmitter linked to mood regulation.² If you are chronically stressed, your body is essentially in survival mode, and sexual desire is one of the first things to get deprioritized. By pulling cortisol back toward normal and nudging serotonin upward, ashwagandha could create conditions where desire has room to surface again.

This distinction matters because it means ashwagandha is unlikely to boost libido in women who are not stressed to begin with. If low desire is caused by relationship issues, medication side effects, or hormonal changes unrelated to stress, there is no good reason to expect ashwagandha to help. The herb appears to work best as a stress-relief tool that happens to have sexual side benefits, not as a direct sexual stimulant.

It Does Not Raise Testosterone in Women

One common misconception is that ashwagandha boosts libido by raising testosterone. In men, there is decent evidence for this: the same meta-analysis found that ashwagandha increased testosterone in men by a meaningful amount but produced essentially no change in women. A separate trial that measured testosterone levels in women taking ashwagandha found a nonsignificant change of less than one percent, no different from what happened in the placebo group.³ The meta-analysis confirmed this gender difference: testosterone rose in men but not in women, and the difference between the sexes was statistically significant.²

The same analysis also found no effect on estradiol levels in either sex, which rules out another popular theory: that ashwagandha works by boosting estrogen. Whatever is happening to improve women’s sexual function scores in the pilot study, it does not appear to be driven by a straightforward change in sex hormones. The cortisol and serotonin pathway looks far more plausible as the primary mechanism.

A Different Story During Perimenopause

There is one exception to the “no hormone changes in women” pattern, and it involves women going through perimenopause. A randomized, placebo-controlled trial of 91 perimenopausal women found that ashwagandha supplementation was associated with a significant increase in estradiol and significant reductions in follicle-stimulating hormone (FSH) and luteinizing hormone (LH) compared to placebo. The ashwagandha group also showed significant improvements in urogenital symptoms, psychological symptoms, and overall quality of life.⁴

The “urogenital” domain in that study includes symptoms like vaginal dryness and changes in sexual desire, so improvements there are directly relevant to the question of whether ashwagandha affects women’s sex drive. And the hormonal picture in perimenopausal women was different from what was seen in younger women: estradiol actually went up, and the pituitary hormones that climb when estrogen drops (FSH and LH) came back down. Testosterone, however, still did not change between groups.⁴

This suggests ashwagandha may be especially relevant for women whose sexual function is declining alongside other perimenopausal symptoms. The estradiol increase is notable because falling estrogen is a major driver of vaginal dryness, reduced arousal, and lower desire during this transition. Whether ashwagandha would produce the same hormonal shift in premenopausal women with healthy estrogen levels is unknown, and extrapolating the result to all women would be premature.

Timing and What to Expect

The clinical trials that showed benefits in women generally ran for eight weeks using standardized root extracts. This aligns with how ashwagandha is thought to work: it modulates stress hormones and neurotransmitters gradually rather than producing an acute, on-demand effect. Nobody should take a dose and expect to feel different that evening. The adaptogenic mechanism takes weeks to shift the hormonal baseline enough for downstream effects on mood, sleep, and sexual function to become noticeable.

Doses in the women-specific studies typically ranged from about 300 mg twice daily to 600 mg daily of a concentrated root extract. The exact formulation matters because “ashwagandha” on a supplement label can mean anything from raw root powder to a highly concentrated withanolide extract, and the clinical trials used standardized preparations. A product containing plain root powder at the same milligram count as a concentrated extract is not comparable.

The men’s data offers a useful parallel here. A placebo-controlled trial in healthy men found that sexual desire scores increased substantially by week eight with a standardized root extract, with a large effect size compared to placebo.⁵ While men and women may respond through different pathways, the eight-week timeline and the importance of using a standardized extract appear consistent across studies in both sexes.

Safety Concerns Worth Knowing About

Ashwagandha is generally well tolerated in healthy adults at the doses used in clinical trials, but “generally safe” is not the same as “safe for everyone.” A review focused specifically on safety flagged significant risks for several groups: pregnant women, people with thyroid disorders, and anyone with liver or kidney problems. The same review noted that multiple cases of liver damage have been reported, raising questions about long-term use.⁶

The thyroid issue deserves special attention for women, since thyroid disorders are far more common in women than in men. Ashwagandha can influence thyroid hormone secretion, with evidence that it may increase T3 and T4 output and subsequently lower TSH.⁷ A meta-analysis confirmed a modest increase in T4 levels.² For someone with a healthy thyroid, this shift is probably inconsequential. For someone already taking thyroid medication like levothyroxine, or someone with an overactive thyroid, stacking ashwagandha on top could push things in a bad direction. If you have any thyroid condition, talk to your doctor before trying it.

As for pregnancy, historical ethnobotanical texts have flagged ashwagandha as a possible abortifacient, though a systematic review found that the evidence behind these claims is weak and plagued by citation distortion. Animal studies showed high tolerability with no significant reproductive toxicity at human-relevant doses, and human clinical data has not shown adverse effects on reproductive health.⁸ Still, the evidence is inconclusive enough that avoiding ashwagandha during pregnancy remains the sensible default.

How Ashwagandha Compares to Shatavari

If you have been searching for herbal options for women’s sexual health, you have probably also come across shatavari (Asparagus racemosus), another adaptogenic herb from the Ayurvedic tradition. A recent three-arm clinical trial compared shatavari root extract alone, shatavari combined with ashwagandha root extract, and placebo in women over eight weeks. Both active groups outperformed placebo on total sexual function scores. But the combination group showed improvements in arousal, lubrication, and orgasm that the shatavari-only group did not reach individually.⁹

The shatavari-only group still improved in overall satisfaction and total scores, but the broader range of improvements in the combination group suggests the two herbs complement each other through different pathways. This is one trial, so it is far from conclusive, but it points toward the possibility that combining adaptogens with different mechanisms could produce more well-rounded effects than either alone.

The Research Is Promising but Thin

A systematic review covering the breadth of human trials on ashwagandha acknowledged that the strongest evidence for any ashwagandha application is stress and anxiety relief. When it comes to sexual function specifically, the review noted that trials often involved small sample sizes and were primarily conducted in India, making generalizability uncertain.¹⁰ The women-specific sexual function trial had just 50 participants. The perimenopause trial had 91. These are reasonable sizes for pilot and early-stage research, but they are not the large confirmatory trials that would let anyone say definitively that ashwagandha reliably improves women’s sexual function.

There is also the question of who funds the research. Many ashwagandha studies are sponsored by supplement companies that manufacture proprietary extracts. That does not automatically invalidate the results, as industry-funded trials can be well-designed, but it does mean independent replication is especially important. The ideal scenario would be a large, multi-center, independently funded trial in women with low desire or clinically diagnosed sexual dysfunction. That trial does not exist yet.

For now, the most honest read of the evidence is that ashwagandha probably helps some women feel more interested in and responsive to sex, primarily by reducing chronic stress. The effect is not dramatic in the way a pharmaceutical intervention might be, and it is not instant. Women going through perimenopause may have an additional hormonal reason to consider it. But anyone hoping for a guaranteed result from a supplement is going to be disappointed, because the science just is not there yet to make that promise.

Thyroid Interactions in Women Already on Medication

Because thyroid disorders are so common in women and because ashwagandha’s thyroid-stimulating properties are well-documented, this interaction deserves a closer look. The endocrine review of ashwagandha research found that the herb’s active compounds can increase the secretion of T3 and T4 by the thyroid gland, with a subsequent decrease in TSH through the feedback loop between the hypothalamus, pituitary, and thyroid.⁷ In someone with subclinical hypothyroidism who is not yet on medication, this could theoretically be helpful. In someone already taking levothyroxine at a carefully calibrated dose, it could tip the balance toward hyperthyroid symptoms like heart palpitations, anxiety, or weight loss.

Women with Hashimoto’s thyroiditis, the most common autoimmune thyroid condition, are in a particularly tricky spot. The autoimmune component means their thyroid function can fluctuate unpredictably, and adding a thyroid-stimulating herb to the mix introduces another variable that makes management harder. If you have Graves’ disease, where the thyroid is already overactive, ashwagandha is essentially contraindicated. The general rule: if you are managing any thyroid condition, ashwagandha is not something to try casually based on social media recommendations. Get your levels checked and discuss it with whoever manages your thyroid care.
