Testosterone is a key hormone for women, not just men. It is made mainly by the ovaries and the adrenal glands, and it supports sex drive, energy, mood, and the strength of your muscles and bones. Women's levels fall gradually with age rather than crashing the way estrogen can around menopause. Both too little and too much testosterone can cause symptoms, and both are checked with a morning blood test read alongside how you actually feel.

What does testosterone do in a woman's body?

Women make roughly a tenth to a twentieth as much testosterone as men, but it is still one of the most abundant active hormones in the female body — often present in higher amounts than estrogen. It comes from the ovaries, the adrenal glands, and the conversion of precursor hormones (such as DHEA) inside fat, skin, and other tissues.

Its main jobs include:

  • Sexual desire and arousal: testosterone influences libido, the intensity of arousal, and orgasm.
  • Energy and mood: it contributes to drive, motivation, and an overall sense of wellbeing.
  • Muscle and bone: it helps build and maintain lean muscle and supports bone density, which matters more after menopause when fracture risk rises.
  • A building block for estrogen: your body converts some testosterone into estrogen, so the two are closely linked. Our explainer on estrogen vs progesterone covers how the other sex hormones fit together.

Because these effects overlap with so many everyday factors — sleep, stress, thyroid, iron, relationships — testosterone is rarely the whole story behind low energy or low libido. It is one piece of a larger hormone picture.

What is a normal testosterone level for a woman?

There is no single "correct" number, and reference ranges differ between laboratories and testing methods. As a rough guide, the Cleveland Clinic puts a typical adult woman's total testosterone at about 15 to 46 ng/dL (roughly 0.5 to 1.6 nmol/L) — a small fraction of a man's level. Your own report will list the specific range your lab used, and that is the number to compare your result against.

Two extra measures often matter more than the headline number:

  • Free testosterone — the small fraction not bound to proteins and available to your tissues.
  • SHBG (sex hormone-binding globulin) — the protein that binds testosterone. When SHBG is high (which happens with age and with oral estrogen), less free testosterone is available even if the total looks normal.

Importantly, there is no medically agreed cut-off that defines "low testosterone" in women, so a number alone does not diagnose a deficiency. Doctors interpret the result together with your symptoms. You can keep your own results in one place with our lab-results tracker.

How does testosterone change with age and menopause?

Unlike estrogen, testosterone does not suddenly plummet at menopause. It declines slowly and steadily from your twenties onward, so that by the mid-forties many women have roughly half the testosterone they had at their peak. Production of adrenal precursors like DHEA also tapers off with age.

A few things change the pattern:

  • Natural menopause causes only a gradual dip in testosterone — the dramatic hormone shift is in estrogen. If you are tracking hot flashes, mood, and libido together, our menopause symptom diary can help you spot patterns, and our menopause hub covers the wider transition.
  • Surgical menopause — having both ovaries removed — can cut circulating testosterone by about half almost overnight, which is why some women notice a sharper change in libido and energy after that surgery.
  • Oral estrogen therapy and the combined pill raise SHBG, which lowers free (usable) testosterone even when total levels look fine.

Falling estrogen after menopause is a separate but overlapping issue; if vaginal dryness or discomfort during sex is part of your picture, see the signs in our guide to low estrogen symptoms.

Signs of low versus high testosterone

Symptoms of low testosterone are vague and shared with many other conditions, while high testosterone tends to produce more specific, visible signs. Use the table as a starting point for a conversation with a clinician, not as a self-diagnosis.

Common signs of low versus high testosterone in women
Low testosterone (nonspecific) High testosterone (more specific)
Persistently low sexual desire that bothers you Excess coarse, dark hair on the face, chest, or back (hirsutism)
Reduced arousal or fewer, less intense orgasms Adult acne, often along the jaw and chin
Ongoing fatigue and low energy Thinning hair or a receding hairline at the scalp
Flat mood or a reduced sense of wellbeing Irregular, infrequent, or missing periods
Loss of muscle tone; harder to build strength Oily skin and, over time, reduced fertility
Possible gradual loss of bone density Rarely: deepening voice or clitoral enlargement (urgent — see below)

What low testosterone can look like

The most studied symptom is persistent, distressing low libido that is not explained by relationship, mood, sleep, or medication factors. Because fatigue and low mood have so many causes, low testosterone is usually considered only after more common explanations — thyroid problems, low iron, depression, poor sleep, and falling estrogen — have been looked at.

What high testosterone can look like

Excess testosterone is most often driven by polycystic ovary syndrome (PCOS), especially when it comes with insulin resistance. Other causes include congenital adrenal hyperplasia and, rarely, hormone-producing tumors of the ovary or adrenal gland. High androgens can travel alongside shifts in other hormones, which is why doctors usually test a small panel rather than testosterone alone.

How is testosterone tested in women?

Testosterone is measured with a simple blood draw, but timing and technique matter:

  • Time of day: levels peak in the morning, so the sample is usually taken between about 7 and 10 a.m.
  • What's measured: total testosterone (bound plus free), often with free testosterone and SHBG. Standard assays are designed for higher male ranges and can be imprecise at the low female end, so results are interpreted cautiously.
  • Cycle timing: if you still have periods, your clinician may pick a particular day of your cycle.
  • The wider panel: when high testosterone is suspected, testing often includes DHEA-S, LH, FSH, and 17-hydroxyprogesterone to look for PCOS or adrenal causes.

The single most important rule: numbers are read together with symptoms. A "normal" result does not rule out a problem, and a slightly low one does not prove testosterone is the cause of how you feel.

How can women support healthy testosterone naturally?

Here is the honest version: no food, workout, or supplement reliably raises a woman's testosterone by a large amount. What lifestyle changes can do is protect your body's hormone-making machinery and directly improve the symptoms often blamed on low testosterone — energy, mood, libido, and strength. That is a meaningful win even when the number barely moves.

  • Strength training. Lifting weights or doing resistance work produces short-lived hormone responses, but the real payoff is building and keeping muscle and bone regardless of your baseline testosterone. Start with our strength and movement guides.
  • Protect your sleep. Short or broken sleep lowers sex hormones and libido. Aiming for 7 to 9 solid hours is one of the highest-value changes you can make.
  • Eat enough, with enough protein. Very low-calorie or very low-fat diets and chronic overtraining can suppress reproductive hormones. Adequate protein, healthy fats, and correcting deficiencies such as vitamin D, zinc, or iron support the whole system — see our nutrition basics.
  • Lower chronic stress. Ongoing stress and high cortisol suppress the reproductive-hormone axis. Practical tools are in our guides on what cortisol does and managing stress and cortisol.
  • Mind your metabolic health. In women, excess visceral fat and insulin resistance tend to raise testosterone (as in PCOS), so weight and blood-sugar management cut the other way if your levels run high.
  • Go easy on alcohol. Heavy drinking disrupts sleep and hormone balance.

What about supplements?

Evidence for over-the-counter "testosterone boosters" in women is weak, and most studies were done in men or in people with a genuine deficiency. Zinc, magnesium, vitamin D, and ashwagandha may help if you are deficient or under stress, but they will not push a normal level higher in any dramatic way. DHEA is a hormone precursor sold as a supplement in some countries; because it is a hormone, not a casual vitamin, it should only be used with a clinician's guidance. If you want to sort useful from hyped, our women's multivitamin buyer's guide and supplement library are good starting points.

When should you see a doctor?

Book a routine appointment if you notice:

  • New or worsening excess facial or body hair, adult acne, scalp hair thinning, or irregular and missed periods — these point toward androgen excess and deserve testing for PCOS or other causes.
  • Persistent low libido that distresses you and does not improve after addressing sleep, stress, relationship factors, and vaginal dryness.

Seek prompt medical care for the red flags of rapidly rising testosterone, which can rarely signal a hormone-producing tumor:

  • A deepening voice, noticeable clitoral enlargement, or fast, dramatic muscle changes.
  • Excess hair growth or male-pattern balding that appears suddenly and worsens quickly.

Please do not treat yourself with testosterone bought online or with compounded pellets — dosing and safety in women require medical supervision.

Natural support versus prescription testosterone therapy

Lifestyle changes are the right first move for most women, and they improve many of the symptoms testosterone is blamed for. For genuinely low sexual desire that causes distress and persists despite addressing the basics, there is an evidence-based medical option: low-dose testosterone prescribed off-label under specialist supervision, most often after menopause. It is not FDA-approved for women, benefits are modest, and it is not a fix for fatigue or mood on its own. We cover who it may suit, how it is monitored, and its limits in our dedicated guide to testosterone therapy for women. Keep this page as your educational foundation, and use that guide when you are ready to weigh the medical route with a clinician.
