What Is Androgen Dominance in Women?

Androgen dominance describes a hormonal state in which androgens, the family of hormones that includes testosterone, dihydrotestosterone (DHT), and dehydroepiandrosterone (DHEA), are disproportionately high relative to estrogen and progesterone. It is not a formal clinical diagnosis in most medical textbooks, but the underlying biology is well-documented: androgen excess can originate from the ovaries, the adrenal glands, or both, and its effects ripple across skin, hair, metabolism, fertility, and mood. The picture is more nuanced than a single blood number being “too high,” because how much androgen actually reaches your tissues depends on binding proteins, enzyme activity, and insulin levels working in concert.

What Androgens Are and Where They Come From

Androgens are often called “male hormones,” but that label is misleading. Everyone produces them. In women, the ovaries and the adrenal glands each contribute a share, with different androgens coming from different zones. Inside the adrenal gland, the outer layers handle cortisol and aldosterone, while the innermost layer produces DHEA and its sulfated form, DHEAS. Several enzymes in that inner zone regulate how much DHEA gets made.¹ The ovaries, meanwhile, produce testosterone directly and also convert precursors into active androgens. When clinicians investigate androgen excess, they look at both sources, because the treatment path depends on which gland is overproducing.²

Once testosterone enters the bloodstream, it can be converted locally in tissues by an enzyme called 5-alpha reductase into DHT, which is the most potent androgen the body makes. DHT binds androgen receptors more strongly than testosterone does, and it drives much of what happens in the prostate, the hair follicle, and the skin’s oil glands.³ Two versions of the enzyme exist (type 1 and type 2), each concentrated in different tissues, which partly explains why androgen effects can show up in one organ but not another.⁴

Why “Total Testosterone” Can Be Misleading

A standard blood test reports total testosterone, but most of that hormone is bound to carrier proteins and inactive. The main carrier is sex hormone-binding globulin (SHBG), which holds testosterone tightly and prevents it from entering cells. A smaller fraction is loosely bound to albumin, and only a sliver circulates freely. It is this free fraction that actually reaches tissues and activates androgen receptors.⁵ That means two people with the same total testosterone level can experience very different degrees of androgen activity depending on how much SHBG they have.

Aging, genetics, body weight, and various diseases all shift the balance between bound and free testosterone. In animal models engineered to overproduce SHBG, total testosterone rose dramatically through feedback loops, yet the free portion stayed roughly the same and actual tissue effects were blunted.⁶ The practical takeaway is that conditions lowering SHBG, such as insulin resistance and obesity, can create functional androgen dominance even when total testosterone looks normal on paper.

The Insulin Connection

Insulin and androgens are tightly linked, especially in women. When insulin levels are chronically elevated, the ovaries get a signal to ramp up androgen production, independent of the usual hormonal regulators from the brain.⁷ High insulin also suppresses the liver’s production of SHBG, so not only do the ovaries make more testosterone, but less of it gets bound up and neutralized. The result is a double hit: more androgens produced and more of them free to act on tissues.

This is why weight gain centered around the midsection, blood sugar swings, and a diet high in refined carbohydrates often worsen symptoms of androgen excess. The hormonal imbalance is not just an ovary problem or an adrenal problem; it is, in many cases, a metabolic one that starts with insulin.

PCOS and Androgen Excess in Younger Women

Polycystic ovary syndrome is the most common endocrine disorder in women of reproductive age, and excess androgen production is its hallmark feature. Inside the ovaries of someone with PCOS, elevated local androgens push early-stage follicles to grow in unusual numbers, creating the characteristic cluster of small follicles visible on ultrasound. Paradoxically, those same androgens then stall the maturation process. The excess follicles appear to inhibit each other, partly through anti-Müllerian hormone signals, preventing any single follicle from being selected for ovulation.⁸ This is why irregular or absent periods are so common with PCOS: without successful ovulation, the cycle stalls.

The visible consequences often bring people to a doctor before the hormonal testing does. Acne along the jawline, excess facial or body hair (hirsutism), and thinning hair on the scalp are all driven by androgens acting on the skin and hair follicles.⁹ These symptoms tend to be particularly distressing, and they can persist even when blood levels of androgens look only mildly elevated, because local tissue conversion of testosterone to DHT amplifies the signal at the skin level.

The Menopausal Shift Toward Relative Androgen Dominance

Androgen dominance is not only a young woman’s issue. During and after menopause, estrogen levels plummet while testosterone declines only modestly. The result is a shift in the ratio: androgens occupy a larger share of the hormonal landscape even though their absolute levels may not be high by any standard reference range.¹⁰ Longitudinal studies tracking women through the menopausal transition confirm this pattern: androgen concentrations declined only slightly compared to the steep drop in estradiol.¹¹

This relative androgen excess is not just a biochemical curiosity. The SWAN study found that the shift predicted the development of metabolic syndrome, a cluster of risk factors including elevated blood pressure, high blood sugar, and abdominal fat gain. For some postmenopausal women, new-onset acne, facial hair growth, or scalp hair thinning that appears for the first time in their 50s is the visible sign of this hormonal rebalancing.¹²

Getting the Testing Right

Measuring androgens accurately turns out to be harder than you might expect. The standard immunoassay methods many commercial labs use have poor precision at the low end of the range, which is exactly where most women’s testosterone levels sit. One review found that routine direct immunoassays can produce results that are effectively meaningless in women and children because of their wide variability.¹³ For reliable results, total testosterone should ideally be measured in the morning, in a fasting state, using a method called liquid chromatography tandem mass spectrometry, which is more accurate than standard immunoassays.¹⁴

Free testosterone is even trickier. The most common quick-and-cheap lab method (a direct radioimmunoassay) has been shown to have unacceptable bias and random variability compared to gold-standard equilibrium dialysis. A calculated free testosterone using the mass action equation, which factors in total testosterone and SHBG levels, tracks the gold standard closely — but the reliability depends on which assays were used for those individual measurements.¹⁵ If you are trying to understand your own androgen status, asking your clinician specifically about the assay method and the lab’s certification is more useful than simply requesting “a testosterone test.”

Metabolic and Liver Effects

Beyond skin and fertility, androgen dominance has metabolic consequences. In a multiethnic study of atherosclerosis, women in the highest third of bioavailable testosterone had roughly 77% higher odds of fatty liver compared to those in the lowest third.¹⁶ The relationship between androgens and liver fat may be partly mediated by insulin resistance, which both drives androgen excess and promotes fat deposition in the liver — a vicious cycle where each condition worsens the other.

The cardiovascular picture is similarly concerning. Relative androgen excess at midlife has been linked to the development of metabolic syndrome, as noted in the SWAN data, and metabolic syndrome is itself a strong predictor of heart disease and type 2 diabetes. This is one reason clinicians increasingly view androgen excess not just as a cosmetic or reproductive problem but as a cardiometabolic risk factor worth monitoring over the long term.

Dietary and Lifestyle Strategies

Because insulin is such a strong driver of androgen production, interventions that improve insulin sensitivity tend to lower androgen levels as a downstream effect. A study of overweight women placed on a low-glycemic diet with mild calorie restriction for 60 days saw total testosterone drop, SHBG rise, and the free androgen index fall significantly.¹⁷ Similar results appeared in women with PCOS specifically, where a restricted-energy, low-glycemic diet led to meaningful drops in total testosterone and the free androgen index, alongside a large increase in SHBG.¹⁸

Strength training combined with carbohydrate reduction has also shown promise. A randomized trial in women with PCOS found that pairing a lower-carbohydrate diet with resistance exercise shifted several hormonal markers, including DHEA and the ratio of luteinizing hormone to follicle-stimulating hormone.¹⁹ The common thread across these studies is that you do not necessarily need to target androgens directly; improving how your body handles glucose and insulin often lowers androgen activity as a side benefit.

Pharmaceutical Options for Reducing Androgen Effects

When lifestyle changes are not enough, several medications target androgen activity at different points in the pathway. Spironolactone, originally a blood-pressure drug, blocks androgen receptors and is widely used off-label for hormonal acne and hirsutism. In one study of women with acne, roughly 86% showed clinically significant improvement on spironolactone, with measurable drops in DHEAS levels, though total testosterone did not change much.²⁰ This suggests the drug works primarily by blocking what androgens do at the receptor rather than by reducing how much is made.

For hair loss driven by androgens, a different class of drugs comes into play: 5-alpha reductase inhibitors, which block the conversion of testosterone to the more potent DHT. Finasteride and dutasteride are the two main options. Head-to-head comparisons consistently show dutasteride outperforming finasteride in hair regrowth, likely because dutasteride inhibits both type 1 and type 2 versions of the enzyme while finasteride mainly targets type 2.²¹ A systematic review confirmed that dutasteride produced significantly greater increases in hair count than finasteride at comparable timeframes, with no meaningful difference in side-effect rates.²² Both drugs require medical supervision and carry specific risks, particularly for women of childbearing age because of the potential for fetal harm.

Supplements and Herbal Approaches

Several supplements have accumulated enough trial data to be worth discussing, though none replaces medical treatment for significant androgen excess. Myo-inositol, a sugar alcohol found in some foods, has been studied extensively in women with PCOS. A meta-analysis of randomized controlled trials found that it reliably lowered fasting insulin and insulin resistance, with a trend toward reduced testosterone that fell just short of statistical significance in the pooled analysis. When supplementation continued for at least 24 weeks, SHBG levels rose significantly.²³ A more recent meta-analysis was somewhat more optimistic, finding significant reductions in both free and total testosterone with inositol treatment compared to placebo.²⁴ The mechanism likely circles back to insulin: inositol improves insulin signaling, which in turn reduces the ovarian stimulus to overproduce androgens.

Spearmint tea gets mentioned frequently in online PCOS communities, and there is some controlled trial data behind it. A 30-day randomized trial in women with PCOS found that drinking spearmint tea twice daily significantly lowered both free and total testosterone.²⁵ An earlier pilot study in women with hirsutism showed a significant drop in free testosterone but not total testosterone after a shorter course of spearmint tea.²⁶ The evidence is still thin — these are small, short studies — but the safety profile is obviously favorable for something you can try alongside other interventions.

Androgen Excess from External Sources

Not all androgen dominance arises from your own glands. Anabolic-androgenic steroids, used in bodybuilding and sometimes prescribed for legitimate medical conditions, flood the body with androgens far beyond physiological levels. The side-effect list is long and serious: acne, high blood pressure, liver damage, abnormal cholesterol, testosterone deficiency after stopping (because the body’s own production shuts down in response), and heart muscle damage.²⁷ Androgen abuse has been associated with increased overall mortality, along with infertility, long-term suppression of natural hormone production, and mental health disturbances including aggression and depression.²⁸

Environmental chemicals can also interfere with androgen signaling, though in more subtle ways. Phthalates, found in many plastics and personal-care products, have been shown to bind to the androgen receptor and block its normal activity, acting as antiandrogens. They can also interact with estrogen receptors, creating a complex mix of hormonal disruption.²⁹ While phthalates tend to suppress rather than promote androgen signaling, their presence in everyday products adds another layer of complexity to the hormonal environment your body is navigating.

Mood, Anxiety, and Androgen Receptors in the Brain

Androgens do not only affect the body from the neck down. The brain is dense with androgen receptors, particularly in regions that regulate emotion. Animal research has shown that excess testosterone exposure during fetal development produces anxiety-like behavior in offspring, and that this effect is mediated directly through androgen receptors in the amygdala. Blocking those receptors reversed the anxiety behavior. The same research found changes in serotonin- and GABA-related gene expression in brain regions tied to emotional regulation.³⁰ While translating animal studies to humans always requires caution, the findings are consistent with clinical observations that women with androgen excess often report higher rates of anxiety and mood disturbance than would be expected from their other symptoms alone.

Testosterone and Life-History Trade-Offs in Female Mammals

Zooming out from clinical medicine, there is a fascinating evolutionary dimension to androgen levels in females. A broad review across female mammals found that testosterone seems to mediate a fundamental trade-off: females with relatively higher testosterone tend to be more dominant, more aggressive, and better at acquiring resources, but they also reproduce later and have fewer offspring. Females with lower testosterone reproduce earlier and more prolifically but tend to be less competitive.³¹ This pattern shows up across species from rodents to primates, suggesting that the tension between androgen-driven competitive ability and reproductive capacity is not a modern pathology but a deeply conserved biological balancing act. Human androgen dominance, in this light, may represent one end of a natural spectrum that only becomes problematic when pushed past the body’s ability to compensate.
