Most women never think about testosterone. It gets discussed as a male hormone, which means the conversation about hormone changes in women tends to begin and end with estrogen. Yet women produce it throughout their lives, and it plays a meaningful role in energy, muscle, bone, mood, and sexual desire. Levels peak in the twenties and decline from there, often falling by roughly half before menopause even begins.
For some women, that causes a few noticeable problems. For others, it contributes to symptoms attributed to stress, aging, or perimenopause without anyone ever measuring the hormone involved. At Optimal Health Associates, Dr. Noel R. Williams has spent more than 30 years caring for women as a board-certified OBGYN, and testosterone is a routine part of how the practice evaluates hormone health. Knowing what to look for is the first step toward feeling like yourself again.
Key Takeaways
- Women produce testosterone in the ovaries and adrenal glands, and levels decline gradually with age.
- Low sexual desire that causes personal distress is the symptom most closely associated with low testosterone in women.
- Symptoms overlap considerably with perimenopause, thyroid conditions, anemia, depression, and medication effects.
- Testing is more complicated in women than in men, and results should always be interpreted alongside symptoms.
- Treatment is individualized, dosed to female physiological ranges, and monitored over time.
What Does Testosterone Do in the Female Body?
Testosterone is an androgen, and while women produce far less of it than men, they produce it continuously. About half comes from the ovaries and half from the adrenal glands.
In women, testosterone contributes to:
- Sexual desire and arousal
- Muscle mass and strength
- Bone density
- Energy and stamina
- Mood and sense of well-being
- Cognitive function
Because it touches so many systems, changes can produce symptoms that seem unrelated. A woman may mention fatigue without connecting it to reduced interest in sex or to strength training that no longer produces results.
Those same symptoms have many other explanations. Thyroid dysfunction, iron deficiency, depression, sleep disruption, and certain medications can all produce a similar picture, which is why a full evaluation matters more than an assumption.
How Do Testosterone Levels Change With Age?
Testosterone in women peaks in the late teens and twenties, then declines gradually. By the forties, levels are often around half of what they were twenty years earlier.
This decline is not tied to menopause the way estrogen is. It happens steadily, on its own timeline, which is part of why it goes unrecognized. Many women notice changes in their late thirties, well before their cycles become irregular.
Surgical menopause is different. Removing both ovaries eliminates roughly half of a woman’s circulating testosterone at once, and the change is often abrupt.
Signs of Low Testosterone in Women
Symptoms tend to be subtler than in men and are more easily attributed to something else.
- Persistent low sexual desire, particularly when it causes distress
- Reduced arousal or difficulty reaching orgasm
- Fatigue that rest does not resolve
- Loss of muscle tone despite consistent activity
- Reduced strength or exercise tolerance
- Low mood or a flattened sense of well-being
- Difficulty concentrating
- Thinning hair or changes in body hair
One symptom on its own rarely means much. Several together, especially when they start affecting your relationships or your work, are worth a conversation.
How Low Testosterone May Affect Sexual Health
Of everything testosterone influences in women, sexual desire has the strongest evidence behind it.
What You Might Notice
Testosterone contributes to libido, arousal, and sexual response. Women with low levels may notice that sexual thoughts occur less often, that interest takes longer to build, or that arousal feels less accessible than it once did.
When It Becomes a Clinical Concern
The clinical term for persistently low desire that causes personal distress is hypoactive sexual desire disorder. The distinction matters, since many women experience a natural decline in libido without being troubled by it.
Bringing this up can feel uncomfortable, which is part of why so many women never do. At Optimal Health Associates, these conversations are routine, and they happen without judgment.
Testosterone Is Rarely the Only Factor
Vaginal dryness, painful intercourse, stress, sleep, and certain medications can all affect desire independently. That is why women’s sexual wellness is best approached as a full evaluation rather than a single hormone test.
Testosterone and Muscle, Bone, and Body Composition
Sexual health receives most of the attention, but testosterone influences your body in ways that are easier to measure and often easier to overlook.
Testosterone supports lean muscle mass and strength. Women with declining levels sometimes notice that the same workouts stop producing the same results or that strength gains take considerably longer than they used to. This becomes more noticeable in the forties and fifties, when muscle loss accelerates for other reasons as well.
Bone density is the other consideration. Testosterone contributes to bone maintenance alongside estrogen, so women who lose both, particularly after surgical menopause, may face greater risk. Testosterone therapy is not prescribed for bone health, but bone density is worth monitoring.
What Can Cause Testosterone to Decline in Women?
Age is only one factor. Testosterone in women can also be affected by:
- Surgical removal of both ovaries
- Primary ovarian insufficiency
- Adrenal or pituitary conditions
- Oral estrogen therapy, which reduces available testosterone
- Oral contraceptives, for the same reason
- Corticosteroid use
- Chronic illness or significant stress
- Chemotherapy or pelvic radiation
Oral estrogen and birth control pills are worth a closer look. Both pass through the liver, which responds by producing more of a protein that binds to testosterone and holds onto it. The testosterone is still in your bloodstream, but much less of it is available for your body to use. That is why a woman on oral hormone therapy can have normal-looking lab results and still feel the effects of low testosterone.
How Is Low Testosterone Diagnosed in Women?
Diagnosing low testosterone in women is harder than in men, and the reason is technical. Blood tests were built to measure the higher concentrations found in men, so at the lower levels typical in women they lose accuracy. There is also no agreed-upon number that defines deficiency in women the way one exists for men.
That is why a lab result on its own does not tell you enough. The process starts with a conversation about your symptoms, your medical history, your medications, and what has changed. Testing is usually done in the morning, when levels are highest, and free testosterone is often the more useful number, since it measures the portion actually available to your tissues rather than the amount bound up and inactive.
A thorough workup rarely stops there, since estradiol, thyroid markers, complete blood count, and iron studies frequently reveal something that matters just as much.
What Testosterone Therapy for Women Involves
When testing and symptoms both point toward low testosterone, treatment is possible. It looks different than it does for men, and it usually falls under bioidentical hormone replacement therapy.
Dosing Is Lower by Design
Treatment for women aims to restore levels to the normal female physiological range, not above it. Going higher does not improve results and increases the likelihood of unwanted effects such as acne, unwanted hair growth, or voice changes.
Pellets and Other Options
Hormone pellets are placed beneath the skin during a brief in-office procedure and release hormones gradually over several months, which avoids the daily application and fluctuating levels of other methods. Compounded creams are another option depending on your needs and preferences.
Sometimes the Answer Is Something Else
For some women, adjusting oral estrogen to a transdermal form, treating a thyroid condition, correcting iron deficiency, or changing a medication resolves the symptoms without touching testosterone at all. Follow-up testing and regular monitoring help confirm that whatever plan you begin is working.
What to Expect After Starting Treatment
Testosterone therapy is not immediate, and the timeline surprises some women who expect to feel different within days.
Changes come gradually over several weeks. Energy and mood often shift first. Improvements in sexual desire usually take eight to twelve weeks, and strength and body composition develop over months, particularly alongside resistance training.
Monitoring matters throughout. Follow-up lab work confirms your levels are landing where they should, and your provider at Optimal Health Associates will ask about side effects that would prompt an adjustment. Doses are based on how you respond rather than a fixed protocol.
Look at the Complete Picture of Your Health
Changes in energy, strength, mood, and desire are frustrating, particularly when you are doing everything right and still feel unlike yourself. Many women are told these changes are simply part of getting older. Some of them are, but you deserve an explanation.
