Quick Answer: Ashwagandha works differently in men and women because it acts on sex-specific hormonal pathways. In men, it consistently increases testosterone and luteinising hormone (LH). In women, it improves oestradiol levels, reduces FSH and LH imbalances, and significantly helps with perimenopause symptoms. Both sexes benefit equally from stress and cortisol reduction, but the reproductive and hormonal effects diverge significantly based on biology.
Most ashwagandha guides treat men and women as the same. They're not, and the research makes this increasingly clear.
How Ashwagandha Affects Hormones Differently in Men and Women
Ashwagandha doesn't work by targeting a single hormone. It works by modulating the hypothalamic-pituitary-adrenal (HPA) axis, the master control system for your body's stress response, and the hypothalamic-pituitary-gonadal (HPG) axis, which regulates reproductive hormones.
The HPA axis effects are essentially the same for everyone: cortisol drops, stress resilience improves, the nervous system settles down. We've covered this in depth in the How Long Does Ashwagandha Take to Work guide.
Where things get sex-specific is the HPG axis. The downstream hormonal effects (what happens to testosterone, oestradiol, LH, FSH, DHEA-S) play out differently depending on your biology, because men and women start from different hormonal baselines and have fundamentally different reproductive systems.
A December 2025 narrative review published in Phytotherapy Research concluded that ashwagandha "notably increases testosterone levels in men and affects estrogen and gonadotrophins in women", two very different hormonal outcomes from the same plant compound.
Here's what that means in practice.
Ashwagandha Benefits for Men
Testosterone Support, What the Research Actually Shows
This is the most-asked question about ashwagandha for men, and the evidence is genuinely solid, with a few important caveats.
A comprehensive 2025 review concluded that "ashwagandha supplementation can increase testosterone levels in adults with no chronic disorders." The effect size in healthy men is in the range of 10–20% increase from baseline, which is meaningful but not the dramatic hormone overhaul some supplement marketing implies.
The mechanism works through three pathways:
- LH stimulation: Ashwagandha increases luteinising hormone, which signals the testes to produce more testosterone
- DHEA-S elevation: Research shows ashwagandha boosts DHEA-S, a precursor steroid hormone that converts into testosterone
- Oxidative stress reduction: Oxidative stress in the testes impairs testosterone production; ashwagandha's antioxidant activity reduces this interference
The effects are most pronounced in men with elevated stress or suboptimal baseline testosterone, because chronically high cortisol directly suppresses testosterone production. By lowering cortisol, ashwagandha removes a major hormonal brake.
In one trial of infertile men taking 675mg/day for 90 days, testosterone rose approximately 17%, LH rose 34%, and sperm count tripled. In healthy, resistance-trained men taking 600mg of KSM-66 daily, testosterone and muscle recovery improvements were measured at 8 weeks, the timeframe that appears consistently across the literature.
Bottom line for men on testosterone: The effect is real, moderate, and most pronounced for men who are stressed, have borderline levels, or are training hard. It won't replace medical treatment for clinical hypogonadism, but as natural support for the higher end of your normal range, the evidence is solid.
Sperm Quality and Male Fertility
Separate from testosterone, ashwagandha has some of the strongest male reproductive research of any botanical supplement.
Multiple trials have documented improvements in:
- Sperm count, significant increases in men with oligospermia (low sperm count)
- Sperm motility, percentage of sperm moving correctly improves meaningfully
- Sperm morphology, proportion of normally shaped sperm increases
- Seminal antioxidant levels, oxidative damage to sperm DNA is reduced
A 2023 double-blind RCT on healthy men found that 8 weeks of ashwagandha root extract produced significant improvements in sexual health markers, not just for infertile men but for healthy adults in normal reproductive health.
The mechanism here is largely antioxidant-driven. The male reproductive system is particularly vulnerable to oxidative stress, and ashwagandha's withanolide compounds appear to have a protective effect on sperm cell integrity.
Muscle Strength and Physical Performance in Men
Ashwagandha has clearer performance benefits for men than for women, partly because the testosterone increase adds an anabolic (muscle-building) dimension to the baseline recovery and endurance benefits both sexes experience.
Studies with resistance-trained men consistently show improvements in:
- Bench press and leg extension strength gains over 8 weeks
- Faster recovery between training sessions
- Reduced exercise-induced cortisol spike (which normally breaks down muscle tissue)
- Greater muscle mass gains compared to placebo over the same training programme
A July 2025 review in the Journal of Education, Health and Sport confirmed that ashwagandha produces improvements in strength, recovery, and hormonal stability "particularly in physically active men."
For men who train regularly, Okie Bee's Men's Vitality Formula pairs well with ashwagandha. It's designed to support the multiple performance pathways (energy, recovery, vitality) that ashwagandha works on from the hormonal side.
Sexual Health and Libido in Men
The research on ashwagandha and male sexual health is more robust than most people realise, and extends beyond testosterone numbers.
A 2025 RCT in the Journal of Ayurveda and Integrative Medicine found that 8 weeks of ashwagandha root extract produced significant improvements in sexual function scores, including satisfaction, performance, and subjective wellbeing, in healthy men without pre-existing sexual dysfunction. This suggests the effect is partly independent of testosterone, likely related to the cortisol reduction, improved blood flow from the adaptogenic response, and the psychological benefits of reduced anxiety.
Ashwagandha Benefits for Women
How Ashwagandha Affects Female Hormones
The hormonal picture for women is more complex and more nuanced than for men. Here's what the clinical evidence actually shows:
Oestradiol: Multiple trials show ashwagandha increases oestradiol in women, most consistently in perimenopausal and postmenopausal women where oestradiol naturally declines. This is clinically meaningful because declining oestradiol drives many of the most disruptive perimenopause symptoms.
FSH and LH: Ashwagandha reduces FSH (follicle-stimulating hormone) and LH levels in perimenopausal women. Both of these hormones tend to rise as ovarian function declines. Normalising FSH and LH levels is associated with reduced hot flashes, improved mood stability, and better sleep during this transition.
Testosterone in women: The picture is mixed. Women do produce testosterone (primarily in the ovaries and adrenal glands), and some case studies show elevated testosterone in women taking ashwagandha. However, large-scale trials in women have not found the consistent, significant testosterone increases seen in men. For most women, testosterone is not the primary hormonal benefit.
The key mechanism in women appears to be the GABA mimetic action of withanolides, which stimulates gonadotropin-releasing hormone and helps to normalise the hormonal feedback loop that becomes dysregulated during perimenopause and chronic stress.
Perimenopause and Menopause Symptom Relief
This is where the women-specific evidence is strongest and most clinically relevant.
A 2020 randomised, double-blind, placebo-controlled trial found that 300mg of ashwagandha twice daily for 8 weeks significantly reduced hot flashes, night sweats, and anxiety scores in perimenopausal women compared to placebo.
A 2025 RCT published in Frontiers in Reproductive Health evaluated ashwagandha root extract in menopausal women over 56 days and found significant improvements in total menopause symptom scores, including vasomotor symptoms, psychological symptoms, and sleep disturbance.
A 2025 Australian review of 14 clinical trials concluded that ashwagandha "can significantly improve vasomotor symptoms, psychological well-being, sleep quality, cognition, stress resilience, fatigue, and sexual function in perimenopausal women."
The KSM-66 clinical trial showed menopausal symptom severity improved by 24% in women taking ashwagandha versus 11% in the placebo group after 8 weeks. That's a clinically meaningful difference, particularly for women who are not candidates for hormone replacement therapy or who prefer a natural approach.
Why this works: The cortisol-lowering effect reduces the stress-driven exacerbation of hot flashes and mood disruption. The oestradiol-supporting effect helps address the hormonal root. Both mechanisms work simultaneously, which is why the symptom relief extends across multiple domains rather than targeting a single complaint.
For women navigating perimenopause alongside daily stress, pairing Okie Bee's Ashwagandha with Magnesium Glycinate covers both the hormonal modulation and the sleep-specific support that this life stage demands.
PCOS and Hormonal Imbalance in Women
PCOS (polycystic ovary syndrome) is a condition driven by abnormal LH:FSH ratios and often elevated androgens. A January 2026 review published in Cureus found that ashwagandha's effect on reducing LH and normalising gonadotropin levels may have implications for PCOS, since the abnormal LH:FSH ratio is a defining feature of the condition.
The evidence here is still emerging and extrapolated partly from perimenopausal data, so it should be treated as promising rather than established. However, the 2024 meta-analysis also found that ashwagandha may improve insulin sensitivity in women, which is highly relevant for PCOS, where insulin resistance often drives hormonal disruption.
If you have PCOS and are considering ashwagandha, the most important step is speaking with your gynaecologist or endocrinologist first, particularly because PCOS treatment is highly individual and the hormonal effects of ashwagandha, while generally beneficial, can interact with existing medication protocols.
Sexual Health and Libido in Women
A frequently overlooked area: ashwagandha has demonstrated benefits for female sexual health in clinical research.
A 2015 double-blind RCT (confirmed in subsequent reviews) found significant improvements in sexual function scores in women taking ashwagandha, including arousal, lubrication, orgasm, and overall satisfaction, compared to placebo. The likely mechanism is multi-pathway: cortisol reduction reduces the psychological barriers to sexual response, oestradiol support improves tissue sensitivity, and the general adaptogenic effect on energy and mood creates conditions where libido can function naturally.
This benefit is relevant across age groups, not just perimenopausal women. Chronic stress is one of the most powerful suppressors of female libido, and addressing cortisol may be as important as any direct hormonal effect.
Thyroid Support for Women
Women are significantly more likely than men to experience thyroid dysfunction, Hashimoto's thyroiditis and hypothyroidism affect women at roughly 7–10 times the rate of men. Ashwagandha's effect on thyroid hormones is therefore more relevant as a topic for women than men.
The evidence shows ashwagandha can increase T3 and T4 in subclinical hypothyroid patients. This is a potential benefit for women with borderline thyroid function, though it's an important caution for women already on thyroid medication, as ashwagandha can amplify the effect. This was covered in the Best Ashwagandha Supplements guide, but it's worth restating here because the population most at risk is predominantly female.
If you're on levothyroxine or other thyroid medications, talk to your doctor before starting ashwagandha.
Benefits Both Men and Women Share Equally
While the hormonal differences are the most interesting part of this comparison, it's important to be clear about where ashwagandha works the same way for everyone, because these are often the most impactful benefits in daily life:
Cortisol reduction, Studies consistently show 20–30% reduction in serum cortisol in chronically stressed adults, regardless of sex. The mechanism is identical.
Cognitive function, Improvements in reaction time, memory, and task performance under pressure are documented in both sexes, driven by the NMDA receptor modulation and stress reduction.
Immune modulation, Withanolides have immune-supporting effects that operate independent of sex hormones.
Sleep quality, Both men and women benefit from the cortisol-lowering and GABAergic effects on sleep architecture. Timing and dosage work the same way for both.
Endurance and recovery, The reduction in exercise-induced cortisol and improvement in VO2 max markers has been documented in both sexes, though the anabolic dimension is more pronounced in men due to testosterone.
Dosage: Is It Different for Men and Women?
The clinical studies use similar dosing across both sexes. There's no established evidence that women require a different dose than men.
| Goal | Recommended Dose | Duration |
|---|---|---|
| Stress and cortisol (both sexes) | 300–600mg standardised extract | 4–8 weeks minimum |
| Testosterone support (men) | 600mg/day (300mg × 2) | 8–12 weeks |
| Perimenopause symptoms (women) | 300mg × 2/day (600mg total) | 8 weeks minimum |
| Sperm quality (men) | 675mg/day | 90 days |
| PCOS / hormonal balance (women) | 300–600mg | Ongoing, with medical supervision |
| Sleep quality (both) | 300mg 30–60 min before bed | 2–4 weeks |
Key point on form: All studies showing sex-specific hormonal benefits used standardised root extract, either KSM-66 or equivalent. Generic ashwagandha, leaf-based products, and unstandardised extracts have not been validated for these hormonal outcomes.

Who Should Be Cautious
Both men and women should be aware of specific situations where ashwagandha requires medical guidance:
Women specifically:
- Pregnancy, not recommended; evidence of uterotonic effects in traditional use
- Hormone-sensitive conditions, oestrogen-sensitive cancers, endometriosis (the mild oestrogenic activity warrants caution)
- Thyroid medication users, ashwagandha can amplify thyroid hormone levels
- PCOS on medication, may interact with hormonal treatment protocols
Men specifically:
- Prostate conditions, the testosterone-elevating effect warrants discussion with a doctor for men with prostate cancer history or BPH
- Hormone-replacement therapy users, potential amplification of exogenous testosterone effects
Both sexes:
- Autoimmune conditions (immune-modulating effects can be unpredictable)
- Pre-surgery (stop 2 weeks before any procedure)
- Liver health monitoring with long-term high-dose use (rare but documented risk)
Frequently Asked Questions
Does ashwagandha increase testosterone in women?
The evidence is mixed. Unlike in men, where testosterone increases are consistently documented, women do not show the same reliable testosterone elevation. Some case studies report increased testosterone in women taking ashwagandha, but large clinical trials in women have not found significant changes in testosterone. Women's primary hormonal benefits from ashwagandha are improved oestradiol levels and normalised FSH/LH ratios, particularly during perimenopause.
Is ashwagandha safe for women to take daily?
Yes, for most women ashwagandha is safe for daily use at 300–600mg of standardised extract. The exceptions are pregnancy (not recommended), women on thyroid medication (requires doctor supervision), and women with hormone-sensitive conditions. A 2025 review of 14 trials found a favourable safety profile in perimenopausal women with no significant adverse events.
Can ashwagandha help with menopause symptoms?
Yes, this is one of the strongest areas of women-specific clinical evidence. Studies show ashwagandha reduces hot flashes, night sweats, sleep disturbance, and anxiety in perimenopausal women. KSM-66 ashwagandha at 300mg twice daily for 8 weeks improved total menopausal symptom scores by 24% versus 11% for placebo in one RCT.
Does ashwagandha affect testosterone the same way in men and women?
No, the effects are clearly different. In men, multiple trials show consistent testosterone increases of 10–20% from baseline, driven by LH stimulation and DHEA-S elevation. In women, the primary hormonal effects are on oestradiol, FSH, and LH, reflecting the different hormonal baseline and reproductive system. A December 2025 review confirmed this sex-specific difference explicitly.
Can men take ashwagandha for fertility?
Yes, the evidence for male fertility is among the most robust in ashwagandha research. Studies document significant improvements in sperm count, motility, morphology, and seminal antioxidant status. One 90-day trial showed sperm count tripled and testosterone rose 17% in men with low sperm count. Benefits have also been found in healthy men without pre-existing fertility issues.
Is ashwagandha good for women with PCOS?
Emerging evidence suggests it may help, primarily by improving insulin sensitivity and potentially normalising the LH:FSH ratio that is dysregulated in PCOS. However, the evidence is still extrapolated partly from perimenopausal data, and PCOS is a complex condition that requires individualised medical management. Speak with your doctor or gynaecologist before starting ashwagandha if you have PCOS.
How long does ashwagandha take to show hormonal benefits?
For testosterone effects in men, studies consistently measure results at 8 weeks of daily use. For perimenopause symptom relief in women, the most cited trial duration is also 8 weeks. For sperm quality improvements in men, 90 days is the timeframe used in most trials. Hormonal changes are slower-building than stress and sleep benefits, patience and consistency are essential.
Can men and women take the same ashwagandha supplement?
Yes. The supplement itself is the same, what differs is which hormonal pathway it most strongly activates based on your biology. Both sexes should look for a standardised KSM-66 or Sensoril extract, minimum 300mg per serving, and the same quality criteria (third-party tested, root-only, withanolide percentage listed). Okie Bee's Ashwagandha is formulated to these standards and is suitable for both men and women.
