Testosterone is often introduced as the “male hormone,” which is a little like calling calcium the “bone mineral” and forgetting that it does several other jobs. Women naturally produce testosterone tooprimarily in the ovaries and adrenal glands, with additional amounts formed when the body converts other hormones.

In women, testosterone contributes to sexual desire, arousal, muscle and bone health, and general well-being. Levels change with age, ovarian function, medications, and health conditions. However, low testosterone in women is medically complicated: symptoms are nonspecific, laboratory ranges vary, and a low blood result does not automatically prove that testosterone is causing someone’s fatigue, mood changes, or low libido.

That distinction matters because the goal is not to chase a laboratory number until it behaves. The goal is to understand the complete health picture and treat the problem that is actually affecting the patient.

What Does Low Testosterone Mean in Women?

Women normally have much lower testosterone concentrations than men. Testosterone circulates in several forms. Some is attached tightly to sex hormone-binding globulin, or SHBG; some is loosely bound to albumin; and a small portion circulates as free testosterone that is readily available to tissues.

A total testosterone test measures both bound and unbound hormone. This means a woman can have a total testosterone result within the laboratory range but relatively little available testosterone because her SHBG level is high. Oral estrogen, certain liver conditions, thyroid changes, and other factors may influence SHBG.

There is no universally accepted testosterone cutoff that diagnoses a female androgen-deficiency syndrome in an otherwise healthy woman. Major endocrine guidelines caution against diagnosing such a syndrome based solely on vague symptoms or one blood test. Even sexual desire does not track neatly with a specific testosterone concentration.

In short, a laboratory result is a cluenot a personality test, a crystal ball, or a complete diagnosis.

Possible Symptoms of Low Testosterone in Women

Some women with unusually low androgen levels report changes in sexual function or physical well-being. Possible symptoms include:

• Reduced sexual desire or fewer sexual thoughts
• Less responsiveness to sexual stimulation
• Difficulty becoming aroused or reaching orgasm
• Reduced sexual satisfaction
• Persistent fatigue or diminished motivation
• Changes in mood, including irritability or a low mood
• Reduced muscle strength or difficulty maintaining lean mass
• A decline in overall sense of well-being

These symptoms are real, but they are not exclusive to low testosterone. An underactive thyroid, anemia, depression, medication side effects, inadequate sleep, chronic pain, relationship stress, vaginal discomfort, and menopause-related estrogen loss can produce a remarkably similar collection of complaints.

Low Testosterone and Low Sexual Desire Are Not Identical

A reduced interest in sex may accompany low testosterone, but desire is influenced by much more than hormones. Stress, body image, privacy, relationship dynamics, past experiences, pain during intercourse, caregiving responsibilities, and exhaustion can all affect libido. After all, the brain is a major sexual organ, and it keeps a very crowded calendar.

Hypoactive sexual desire disorder, or HSDD, refers to persistently low sexual desire that causes significant personal distress and is not better explained by another medical condition, mental health issue, medication, substance, or relationship problem. A woman who is comfortable with her level of desire does not have a disorder simply because her interest differs from someone else’s.

What Causes Low Testosterone in Women?

Aging and Reproductive Changes

Androgen levels generally decline across adult life, although the pattern varies. Natural menopause does not always cause a sudden testosterone collapse on the day periods stop. The decline is often gradual and may begin well before menopause.

Estrogen loss during menopause can nevertheless contribute to vaginal dryness, painful sex, sleep disruption, hot flashes, and mood changes. These symptoms may reduce desire even when testosterone is not the main problem.

Removal or Reduced Function of the Ovaries

Removal of both ovaries, known as bilateral oophorectomy, can produce a more abrupt reduction in ovarian hormones. Premature ovarian insufficiency, chemotherapy, radiation, and certain ovarian disorders may have similar effects. Women who experience surgical menopause sometimes notice a sudden change in desire, arousal, or comfort rather than the slower transition associated with natural menopause.

Adrenal or Pituitary Disorders

The adrenal glands produce androgen precursors, while the pituitary gland helps regulate several reproductive and adrenal hormones. Adrenal insufficiency, pituitary disease, pituitary surgery, tumors, or disorders affecting the hypothalamus may reduce hormone production. These conditions often cause additional symptoms, such as menstrual changes, low blood pressure, unexplained weight loss, headaches, visual changes, or abnormalities involving other hormones.

Medications and Medical Treatments

High-dose or long-term corticosteroids, some opioid medicines, certain estrogen preparations, and treatments that suppress ovarian function may affect androgen production or availability. Oral estrogen can raise SHBG, potentially lowering free testosterone even if total testosterone changes little.

Meanwhile, antidepressantsparticularly some selective serotonin reuptake inhibitorscan lower sexual desire or make orgasm more difficult without necessarily lowering testosterone. Reviewing medications is therefore an important part of the investigation.

Chronic Illness, Undernutrition, and Extreme Exercise

Severe illness, significant calorie restriction, very low body weight, rapid weight loss, or strenuous training without adequate recovery can disrupt the hypothalamic-pituitary-ovarian system. Menstrual periods may become irregular or stop, and several hormonesnot just testosteronemay change.

Chronic kidney disease, liver disease, diabetes, neurological disorders, cancer, and HIV may also affect energy, sexual function, or hormone regulation. The underlying condition may be more clinically important than the testosterone result itself.

How Low Testosterone in Women Is Diagnosed

Evaluation should begin with a detailed conversation rather than an instant prescription. A clinician may ask about the onset and duration of symptoms, menstrual history, menopause status, pregnancy plans, ovarian surgery, medications, sleep, mental health, sexual comfort, relationships, and chronic illnesses.

A physical or pelvic examination may identify vaginal dryness, tissue thinning, vulvar skin disease, pelvic-floor tenderness, or another source of painful sex. These findings can redirect treatment toward the actual problem.

Blood Tests That May Be Considered

Depending on the symptoms, testing may include:

• Total testosterone, preferably measured with an accurate assay suitable for the low female range
• SHBG and, when appropriate, calculated free testosterone
• Estradiol, follicle-stimulating hormone, and luteinizing hormone
• Thyroid-stimulating hormone
• Prolactin
• DHEA sulfate when adrenal function is relevant
• A complete blood count, metabolic testing, or other studies for fatigue and chronic illness

Hormone levels vary with age, menstrual timing, medications, testing methods, and laboratory reference ranges. A surprising result may need to be repeated. Clinicians should interpret the number alongside symptoms and medical history rather than labeling every low value as a disease.

Importantly, testosterone testing is not used to establish HSDD because no blood concentration separates women with HSDD from women without it. When testosterone treatment is being considered, baseline testing is mainly useful for identifying unexpectedly high levels and guiding safe monitoring.

Treatment Options for Low Testosterone in Women

Treat the Underlying Cause First

Treatment depends on what the evaluation finds. It might involve correcting thyroid disease or anemia, improving nutrition, treating depression, managing chronic pain, adjusting a medication, or addressing sleep problems. A patient should never stop a prescribed drug independently, but a clinician may change the dose, timing, or medication when sexual side effects are significant.

If vaginal dryness or painful sex is suppressing desire, lubricants, vaginal moisturizers, pelvic-floor physical therapy, or appropriate treatments for genitourinary syndrome of menopause may help. Local vaginal estrogen, vaginal DHEA, or other prescription options may be considered based on individual risks and symptoms.

Sex therapy, cognitive behavioral therapy, and couples counseling can also be valuable. Their use does not mean the symptoms are “all in someone’s head.” Sexual function is biological, psychological, and interpersonal, usually all before breakfast.

When Testosterone Therapy May Be Considered

The only well-supported indication for systemic testosterone therapy in women is HSDD in appropriately evaluated postmenopausal women. Evidence does not support prescribing testosterone routinely for ordinary aging, weight loss, memory improvement, depression, fatigue, osteoporosis prevention, or muscle building.

The United States does not currently have an FDA-approved testosterone formulation specifically designed for women. When specialists prescribe it for HSDD, treatment is therefore off-label and generally involves a carefully reduced dose of a transdermal product. The goal is to keep blood levels within the normal premenopausal female rangenot to create a miniature bodybuilding program.

Injections and implanted pellets can produce unnecessarily high or difficult-to-reverse concentrations. Compounded products may have inconsistent dosing and lack the quality and safety data required of FDA-approved formulations. Oral testosterone is generally discouraged because of unfavorable effects on cholesterol and liver-related concerns.

Monitoring and Possible Side Effects

Before treatment, a clinician may review breast and cardiovascular health, liver function, cholesterol, pregnancy potential, medication interactions, and baseline testosterone and SHBG levels. Testosterone is not appropriate during pregnancy, while trying to conceive, or while breastfeeding because androgen exposure may harm fetal or infant development.

Possible adverse effects include acne, oily skin, increased facial or body hair, and scalp hair thinning. Excessive dosing may cause voice deepening or enlargement of the clitoris, changes that may not fully reverse. Long-term cardiovascular and breast safety data remain limited, particularly for women at elevated baseline risk.

Levels are commonly rechecked after treatment begins and periodically once stable. If there is no meaningful improvement after an adequate trialoften three to six monthstherapy should usually be discontinued. More hormone is not the solution to a treatment that is not working.

Can Low Testosterone in Women Be Prevented?

Age-related hormonal changes, medically necessary ovary removal, and many endocrine disorders cannot be prevented. However, women can reduce avoidable contributors and protect the areas that hormone changes may affect.

• Eat enough protein, calories, calcium, and vitamin D for personal health needs.
• Include resistance and weight-bearing exercise to support muscles and bones.
• Prioritize sleep and seek treatment for persistent insomnia or sleep apnea.
• Manage diabetes, thyroid disease, cardiovascular risks, and other chronic conditions.
• Avoid smoking and moderate alcohol intake.
• Discuss sexual side effects before stopping antidepressants or other medicines.
• Seek help for painful sex, mood symptoms, or menstrual changes instead of assuming they are unavoidable.
• Avoid over-the-counter “testosterone boosters,” unregulated hormones, and borrowed prescriptions.

These measures do not guarantee a higher testosterone result. They can, however, improve energy, strength, sexual comfort, and overall health while helping clinicians identify symptoms that still require investigation.

When to Speak With a Healthcare Professional

Consider making an appointment if reduced desire, fatigue, menstrual changes, sexual pain, or weakness is persistent, distressing, or affecting daily life. Evaluation is especially important after ovarian surgery, chemotherapy, radiation, or a major medication change.

Prompt medical attention is appropriate for severe weakness, fainting, persistent vomiting, very low blood pressure, sudden headaches, vision changes, or other signs of adrenal or pituitary illness. Low testosterone itself is rarely an emergency, but the condition causing hormonal changes sometimes requires urgent treatment.

Conclusion

Low testosterone in women is not diagnosed by matching a few broad symptoms to a laboratory number. Desire, energy, mood, muscle health, and sexual satisfaction are influenced by several hormones as well as physical health, medications, sleep, pain, and personal circumstances.

A thoughtful evaluation can identify whether unusually low androgen production, estrogen loss, a medical disorder, medication effects, or nonhormonal factors are involved. Testosterone therapy may help selected postmenopausal women with carefully diagnosed HSDD, but it requires conservative dosing, regular monitoring, and realistic expectations. For everyone else, treating the underlying cause is usually more effective than asking one hormone to perform the entire orchestra.
