Testosterone in Women: Yes, You Have It Too

The stubborn myth that testosterone is a male hormone has caused a lot of confusion — and a lot of women being told their symptoms don't count. In fact, women's bodies produce testosterone every day, and it does meaningful work. Not as much of it as men make, but enough that low or high levels are noticeable.

This guide covers what testosterone actually does in women, how much is normal, what low or high testosterone looks like, why levels shift, and how to support balance — with the honest caveat that hormone therapy in women is a specialized medical topic that belongs with a qualified clinician.

Do women really have testosterone?

Yes — and calling it a "male hormone" was always more sociology than biology. Both men and women produce estrogen, progesterone and testosterone. The difference is in the ratios, not the ingredients.

In women, testosterone is produced by the ovaries and the adrenal glands, in roughly equal amounts. It circulates in the bloodstream — mostly bound to a carrier protein called SHBG — and a smaller "free" fraction is what actually acts on tissues. Its receptors are found in muscle, bone, fat, brain, breast tissue, ovaries, skin and clitoris. Wherever it lands, it has a specific job to do.

Testosterone can also be converted to estrogen through an enzyme called aromatase. So even outside its direct action, testosterone is quietly feeding into your overall hormone economy.

What testosterone does in women

Testosterone is an androgen — one of a class of hormones with characteristic effects on tissue. Its key roles in women include:

Libido and sexual response. Testosterone is a major driver of desire in women, though libido is complex and shaped by many factors (relationship, stress, sleep, mood, medications). Persistent low libido that doesn't respond to those other factors sometimes has a testosterone component.

Energy and mood. Testosterone influences motivation, drive and mood stability. Very low levels can feel like a flatness that's hard to name — nothing is wrong, but nothing feels lit up either.

Muscle mass and strength. Testosterone supports muscle protein synthesis, which is part of why building muscle takes deliberate effort — women have less of the hormone that helps automatically. Adequate testosterone helps you keep the muscle you build.

Bone density. Alongside estrogen, testosterone supports bone health. Its decline over time contributes to gradual bone loss, especially after menopause.

Cognition. Emerging research suggests testosterone plays a role in mental clarity, verbal memory and spatial reasoning, though this area is still being mapped out.

Skin, hair and body composition. Testosterone influences oil production, hair growth patterns, and body fat distribution. In balance, it's part of what makes you you; out of balance in either direction, its skin and hair effects become noticeable.

Normal testosterone levels in women

Reference ranges vary by lab, but total testosterone in women is typically in the range of about 15 to 70 ng/dL. Men's range is roughly 300 to 1000 ng/dL — so women make somewhere between 5 and 10 percent of the male level. Even so, the biology cares about that smaller amount.

Free testosterone (the unbound, biologically active fraction) is measured in even smaller numbers and can be more informative in some situations. SHBG — the protein testosterone binds to — matters too: higher SHBG means less free testosterone available to act, and lower SHBG means more.

An honest note about testing: a single testosterone measurement in isolation rarely tells the full story. Levels vary across the day (they're highest in the morning), fluctuate a little across the cycle, and need to be interpreted alongside symptoms, SHBG, and the rest of your hormone picture. This is a job for a clinician who understands the nuance.

How testosterone changes across life

20s to early 30s. Testosterone is at its peak. Libido, energy and muscle-building capacity are typically at their strongest.

Mid-30s onward. Testosterone begins a gradual, steady decline — roughly 1 to 2 percent per year — that continues throughout life. It's slow enough that most people don't notice year to year, but the cumulative effect can be meaningful.

Perimenopause and menopause. The transition doesn't cause a dramatic drop in testosterone the way it does for estrogen — but ovarian testosterone production does decline. Combined with the earlier gradual decline, many women feel the difference.

After ovary removal. Surgical removal of the ovaries (oophorectomy) causes an abrupt drop in testosterone as well as estrogen — often more noticeable than natural menopause.

Signs of low testosterone in women

Because testosterone acts on so many systems, "low" can look like a lot of things:

• Low libido that isn't explained by other factors
• Persistent fatigue not fixed by rest
• Low mood, motivation, or a general dulling of drive
• Difficulty building or maintaining muscle despite training
• Brain fog or difficulty concentrating
• Thinning bones over time

Low testosterone in women is under-recognized and often missed — partly because the symptoms overlap with so many other conditions (thyroid, depression, anemia, sleep apnea, low iron, poor recovery from training). That's exactly why a proper medical workup matters rather than a self-diagnosis.

Signs of high testosterone in women

High testosterone tends to make itself known through androgen-driven changes:

• Persistent acne, especially along the jaw and chin
• Excess facial or body hair (hirsutism)
• Scalp hair thinning in a male-pattern distribution
• Irregular or absent periods
• Deepening voice (uncommon; suggests significantly elevated levels)
• Increased muscle mass or body composition changes
• Oily skin

The most common cause of mildly to moderately elevated testosterone in women is PCOS. Less commonly, higher levels can come from other endocrine conditions or medications. Sudden or rapidly worsening symptoms deserve prompt medical attention.

Testosterone and PCOS

PCOS — polycystic ovary syndrome — is the most common cause of higher testosterone in women. In PCOS, the interplay between insulin resistance and ovarian function raises androgen production, which drives the visible signs: acne, excess hair, hair thinning and irregular cycles. Not everyone with PCOS has elevated testosterone on blood tests, and not every person with elevated testosterone has PCOS. It's the pattern that matters.

If you're seeing the constellation of irregular periods plus androgen-driven skin or hair changes, our full guide to PCOS walks through the diagnostic picture. And if PCOS is on your mind, please see a clinician — it's diagnosed and managed medically.

How to support healthy testosterone in women

You can't fine-tune testosterone with willpower, but you can create conditions that support healthy production and use of it.

Strength train. Resistance training is one of the most reliably supportive things you can do for testosterone in women — plus its downstream benefits on muscle, bones and metabolism are enormous in their own right.

Eat enough, and eat enough protein. Chronic under-eating and low protein intake both suppress testosterone and the systems it supports. Adequate fuel matters.

Sleep. Testosterone production is tied to sleep quality. Short or fragmented sleep suppresses it, and this shows up quickly.

Manage stress. Chronic cortisol elevation competes with sex-hormone production. This is a real biological trade-off, not a wellness cliché.

Watch alcohol. Heavy alcohol use suppresses testosterone in women as it does in men.

Address underlying issues. If low testosterone is one symptom of a broader picture — thyroid disease, iron deficiency, poorly managed diabetes, chronic under-eating — treating the underlying issue often does more than any targeted intervention.

The single most testosterone-supportive thing most women can do is lift weights, sleep well, and eat enough. Everything else is a rounding error.

A note on testosterone therapy for women

Testosterone therapy in women is a real medical option — but a specialized one, with limited approved indications (mainly for menopausal low libido that hasn't responded to other approaches). It's not a general wellness supplement, and using higher doses than recommended can cause exactly the androgen side effects we listed above.

If you think testosterone therapy might be relevant to you, please see a clinician who specializes in hormone health. They can assess whether it's appropriate, at what dose, and how to monitor it. Buying testosterone online or dosing without medical supervision is genuinely risky.

When to see a doctor

Talk to a clinician if you notice:

• Persistent low libido that troubles you
• Ongoing fatigue not explained by sleep or life factors
• Difficulty building or keeping muscle despite training
• Signs of high androgens — acne, excess facial or body hair, scalp hair thinning
• Irregular cycles with any of the above
• Any sudden or rapidly worsening symptom — always worth prompt attention

A good clinician will test more than testosterone in isolation — they'll look at SHBG, other hormones, thyroid, iron, and the full picture. That's the standard to hope for.

Frequently asked questions

Do women have testosterone?

Yes. Women produce testosterone in the ovaries and adrenal glands, at roughly one-tenth to one-twentieth the amount men produce. Despite the smaller quantity, testosterone plays real roles in women's libido, energy, mood, muscle mass, bone density and cognition.

What are symptoms of low testosterone in women?

Low testosterone in women can include low libido, persistent fatigue, low mood or motivation, difficulty building or maintaining muscle, and a general dulling of energy. It becomes more common after menopause, with certain medications, or after removal of the ovaries. It should be assessed by a clinician, not self-diagnosed.

What are symptoms of high testosterone in women?

Higher-than-typical testosterone in women can cause acne, excess facial or body hair (hirsutism), scalp hair thinning, irregular or absent periods, deepening voice, or changes in muscle mass. It is a common feature of PCOS and warrants a clinician's assessment to identify the cause.

How much testosterone do women naturally have?

Women typically have total testosterone in the range of roughly 15 to 70 ng/dL, though normal ranges vary by lab and by life stage. Free testosterone — the biologically active fraction — is a small percentage of that. Levels naturally decline gradually from the 20s onwards and drop further around and after menopause.

How can women support healthy testosterone naturally?

Strength training, sufficient protein, adequate sleep, stress management and avoiding chronic under-eating all support healthy testosterone levels. These are foundations; testosterone therapy in women is a specialized medical decision with limited approved indications and should only be considered with a qualified clinician.
