Low Testosterone in Women: Symptoms, Causes, Testing, and Treatment

Testosterone is often called a “male hormone,” but women need it too. In women, testosterone plays a role in sexual desire, energy, mood, muscle support, motivation, and overall sense of vitality. When levels are low or when the body is not responding well to hormonal changes, some women may notice symptoms that affect daily life.

Low testosterone in women can be confusing because the symptoms overlap with menopause, thyroid issues, stress, depression, poor sleep, nutrient deficiencies, relationship strain, medication side effects, and other hormone changes. That is why testing, medical history, and a full wellness evaluation matter.

At Tucson Wellness MD, hormone concerns are reviewed through a whole-body lens that may include menopause support, metabolic health, peptide therapy guidance when appropriate, natural healing strategies, and longevity care.

Why Testosterone Matters for Women

Women naturally produce testosterone, primarily through the ovaries and adrenal glands.

Testosterone plays a role in sexual function and other physiological processes, but symptoms such as fatigue, brain fog, mood changes or reduced exercise performance should not automatically be attributed to testosterone levels.

Current evidence is strongest for testosterone therapy in appropriately evaluated women with hypoactive sexual desire disorder, particularly after menopause.

A testosterone blood level alone does not establish the diagnosis of HSDD and should be interpreted alongside symptoms, health history and other possible contributors.

Primary Symptoms

There is no single symptom pattern that proves a woman has clinically meaningful testosterone deficiency.

Symptoms such as low sexual desire, fatigue, mood changes, reduced motivation and difficulty building muscle can overlap with:

• Menopause
• Thyroid disorders
• Iron deficiency or anemia
• Poor sleep
• Depression or anxiety
• Medication side effects
• Relationship factors
• Nutritional deficiencies
• Metabolic conditions

Of these concerns, persistent low sexual desire associated with personal distress has the strongest evidence base for considering testosterone therapy after other contributors have been evaluated.

Symptoms Sometimes Associated With Hormonal Changes

Symptom	How It May Feel	Other Possible Causes
Low sexual desire	Reduced sexual interest or fewer sexual thoughts	Menopause, relationship factors, medications, pain, vaginal dryness, depression
Fatigue	Lower stamina or persistent tiredness	Anemia, thyroid disease, poor sleep, stress, depression
Mood changes	Irritability, reduced motivation or low mood	Menopause, mental-health conditions, sleep problems, medications
Difficulty building muscle	Reduced strength or slower progress	Aging, inadequate protein, inactivity, training factors
Brain fog	Difficulty concentrating or mental fatigue	Sleep problems, menopause, thyroid disorders, stress, medication effects

These symptoms are not specific to low testosterone and should not be used alone to decide whether testosterone therapy is appropriate.

Low Sex Drive

Low sex drive is one of the most discussed symptoms linked with low testosterone in women. Some women describe it as a Low sexual desire becomes clinically important when it is persistent, causes personal distress and is not better explained by factors such as:

• Relationship difficulties
• Depression or anxiety
• Pain during sex
• Vaginal dryness
• Medication effects
• Major life stress
• Other medical conditions

Experts recommend a biopsychosocial assessment before testosterone therapy is considered.

Physical Exhaustion

Persistent fatigue deserves evaluation, but fatigue is not a specific marker of low testosterone in women.

Possible causes include:

• Iron deficiency or anemia
• Thyroid disorders
• Sleep apnea or poor sleep
• Depression
• Chronic stress
• Nutritional deficiencies
• Blood sugar problems
• Medication effects
• Chronic illness

Current expert guidance does not establish testosterone therapy as a general treatment for fatigue or low energy in women.

Mood Disturbances

Mood changes can occur during perimenopause and menopause, but they should not automatically be attributed to low testosterone.

Possible contributors include:

• Estrogen changes
• Sleep disruption
• Depression
• Anxiety
• Thyroid disorders
• Medication effects
• Chronic stress
• Relationship or life changes

Current evidence does not support prescribing testosterone primarily to improve mood, cognition or general well-being in women.

Other Symptoms That May Need Evaluation

Some women seek hormone evaluation because of concerns such as:

• Brain fog
• Reduced motivation
• Changes in muscle strength
• Reduced exercise tolerance
• Changes in body composition
• Bone-health concerns

These symptoms can have many causes and do not establish that testosterone treatment is needed.

Leading Causes

Low testosterone in women can happen for several reasons. The most common include natural aging and menopause, ovary removal or dysfunction, medications, and other health or lifestyle factors.

Natural Aging & Menopause

Testosterone levels tend to decline with age. Many women also experience hormonal changes during perimenopause and menopause that can affect energy, libido, mood, sleep, and body composition.

Menopause can also bring changes in estrogen and progesterone, which may overlap with symptoms linked to testosterone. This is why hormone care should evaluate the whole picture, not one lab marker in isolation.

A menopause-focused plan may include:

• Symptom review
• Hormone testing when appropriate
• Sleep support
• Nutrition support
• Strength training
• Stress management
• Sexual health discussion
• Natural healing strategies
• Longevity care planning

Women comparing hormone stages may also review perimenopause vs menopause and menopause therapy in Tucson. Declining testosterone levels with age do not by themselves establish a disease or indicate that testosterone replacement is necessary. Treatment decisions should be based on symptoms, clinical assessment and evidence-based indications rather than trying to restore a younger person’s hormone number.

Ovary Removal or Dysfunction

The ovaries contribute to androgen production, so surgical removal of both ovaries can cause a more abrupt change in hormone levels.

Symptoms after surgery may involve changes in estrogen as well as testosterone.

A provider should evaluate the full hormonal picture rather than assuming symptoms are caused by testosterone alone.

Medications

Certain medications may affect libido, energy, mood, or hormone activity. Some may reduce testosterone levels directly, while others may create symptoms that look like low testosterone.

Possible contributors may include:

• Some antidepressants
• Oral contraceptives
• Certain blood pressure medications
• Opioids
• Glucocorticoids
• Some anti-androgen medications
• Certain treatments that affect ovarian function

Never stop a medication without speaking with your prescribing provider. If symptoms started after a medication change, bring that timeline to your appointment.

Other Factors

Several non-hormonal factors can contribute to symptoms similar to low testosterone.

Other factors may include:

• Chronic stress
• Poor sleep
• Low protein intake
• Nutrient deficiencies
• Overtraining
• Sedentary lifestyle
• Insulin resistance
• Thyroid disorders
• Depression or anxiety
• Chronic inflammation
• Major weight changes
• Alcohol overuse

This is why a comprehensive approach matters. Sometimes the answer is hormone support. Sometimes it is nutrition, sleep, strength training, metabolic care, or stress recovery. Often, it is a combination.

When to Consider Treatment

Testosterone therapy should not be used simply because a blood test shows a low value or because a woman feels tired.

Current international consensus supports testosterone therapy primarily for postmenopausal women with hypoactive sexual desire disorder after a thorough biopsychosocial assessment.

Before treatment, a provider should review:

• Sexual symptoms and level of distress
• Menopause status
• Relationship factors
• Mental health
• Medications
• Vaginal symptoms or pain
• Medical history
• Relevant laboratory testing
• Potential benefits and risks

Evidence for testosterone treatment of fatigue, mood problems, cognition, muscle gain or general anti-aging remains insufficient.ld include monitoring. For related hormone support, learn more about TRT for women and hormone imbalance symptoms.

How Low Testosterone in Women Is Evaluated

Evaluation should begin with symptoms and medical history rather than laboratory testing alone.

A provider may review:

• Sexual health concerns
• Menopause status
• Medication use
• Relationship or psychological factors
• Thyroid symptoms
• Sleep
• Nutrition
• Other medical conditions

When testosterone therapy is being considered, testosterone testing can help establish a baseline and monitor treatment.

However, total testosterone should not be used by itself to diagnose HSDD.

Is Testosterone FDA Approved for Women?

There is currently no testosterone product specifically approved by the U.S. FDA for treatment of women.

When testosterone is prescribed to women in the United States, treatment is therefore off-label.

Patients should understand:

• Why treatment is being recommended
• What evidence supports it
• What formulation is being used
• How the dose differs from male dosing
• How testosterone levels will be monitored
• What side effects require dose adjustment or discontinuation

Recent FDA discussions have continued to emphasize the need for additional research and female-specific approved formulations.

What Treatment May Involve

Treatment depends on the actual cause of symptoms.

For some women, the first step may involve:

• Menopause treatment
• Vaginal or sexual-health care
• Medication adjustment
• Thyroid evaluation
• Treatment of iron deficiency
• Sleep improvement
• Nutrition support
• Mental-health support
• Resistance training

For appropriately evaluated women with HSDD, testosterone therapy may be considered after risks, benefits and off-label use are discussed.

Low Testosterone Treatment Options for Women

Treatment Approach	When It May Be Relevant	Important Consideration
Testosterone therapy	Select women with carefully evaluated HSDD	Requires physiologic dosing and monitoring
Menopause therapy	Vasomotor, vaginal or other menopause symptoms	Treatment depends on symptoms and medical history
Vaginal treatment	Dryness, pain or genitourinary symptoms	May improve sexual comfort without testosterone
Medication review	Libido or mood changes after medication changes	Never stop medications without prescriber guidance
Nutrition and sleep care	Fatigue or nutrient-related concerns	Treat identified contributors
Strength training	Muscle strength and physical function	Useful regardless of testosterone treatment

Possible Risks of Testosterone Therapy in Women

Possible androgen-related effects include:

• Acne
• Oily skin
• Increased facial or body hair
• Scalp hair thinning
• Voice deepening
• Changes in cholesterol or other laboratory markers

Some androgenic effects may not fully reverse after treatment stops.

Long-term safety data for testosterone therapy in women remain limited, particularly regarding cardiovascular and breast outcomes. For evidence-based recommendations on testosterone therapy in women, review the Global Consensus Position Statement on Testosterone Therapy for Women.

Questions to Ask Your Provider

Before starting treatment, ask:

• What else could be causing my symptoms?
• Do my labs match my symptoms?
• Am I in perimenopause or menopause?
• Could my medications be affecting libido or energy?
• What are the risks and benefits of treatment?
• How will my levels and symptoms be monitored?
• What side effects should I watch for?
• What happens if I do not respond?
• Are there non-hormonal options I should try first?
• Good hormone care should feel measured, not rushed.

How Tucson Wellness MD Supports Women’s Hormone Health

Tucson Wellness MD can evaluate symptoms that may occur during perimenopause, menopause or other hormonal changes.

Evaluation may include:

• Medical and medication history
• Menopause stage
• Sexual-health concerns
• Sleep
• Nutrition
• Thyroid or metabolic concerns
• Appropriate laboratory testing
• Discussion of evidence-based treatment options

Testosterone therapy should be considered only when the potential indication, expected benefit and monitoring plan are clear.

Final Thoughts

Women naturally produce testosterone, but symptoms alone cannot establish that testosterone levels are the cause of fatigue, mood changes, brain fog or reduced physical performance.

The clearest evidence for testosterone therapy is for appropriately evaluated women with hypoactive sexual desire disorder, particularly after menopause.

A careful assessment should identify other possible causes before treatment begins.

When testosterone is prescribed, the goal should be physiologic dosing, symptom improvement and careful monitoring rather than maximizing hormone levels.

Frequently Asked Questions About Low Testosterone in Women

Can women have low testosterone?

Women naturally produce testosterone, and levels generally change with age and reproductive stage. However, a low blood level alone does not establish a condition that requires testosterone treatment.

What symptom has the strongest link to testosterone treatment in women?

Persistent low sexual desire associated with personal distress, known as hypoactive sexual desire disorder, has the strongest evidence supporting testosterone therapy in appropriately evaluated postmenopausal women.

Can low testosterone cause fatigue in women?

Fatigue may occur alongside hormonal changes, but it has many possible causes. Iron deficiency, thyroid disorders, poor sleep, stress, depression, medication effects and other health conditions should also be considered.

How is low testosterone evaluated in women?

Evaluation includes symptoms, medical history, menopause status, medications and other possible causes. Testosterone testing may be used as part of the assessment and to monitor treatment, but a blood level alone does not diagnose HSDD.

Is testosterone therapy FDA approved for women?

There is currently no testosterone product specifically approved by the U.S. FDA for women. Testosterone prescribed to women in the United States is therefore used off-label.

Is testosterone therapy safe for women?

Testosterone may be appropriate for select women under medical supervision. Possible side effects include acne, oily skin, increased hair growth, scalp hair thinning and voice changes. Long-term safety data remain limited.

Does testosterone therapy help women with brain fog or low energy?

Current evidence does not establish testosterone therapy as a general treatment for brain fog, fatigue, mood problems or overall vitality in women.

Who may be considered for testosterone therapy?

Current consensus supports considering testosterone primarily for postmenopausal women with diagnosed hypoactive sexual desire disorder after other biological, psychological and relationship factors have been evaluated.
