Testosterone Therapy for Women: Why This Hormone Deserves Attention

Most people associate testosterone with male health, but this hormone is far too important to be claimed by one sex. Women produce testosterone throughout their lives, and when levels decline, the effects can be surprisingly broad, touching energy, mood, cognition, and sexual wellbeing. Despite decades of clinical evidence, testosterone therapy for women remains one of the most under-discussed topics in modern medicine.

Women Produce More Testosterone Than Oestrogen

This surprises many people, but it is biochemically true. The ovaries and adrenal glands produce testosterone in quantities that actually exceed oestradiol production at most points during the menstrual cycle. Testosterone is, in fact, a precursor to oestrogen, meaning the body converts it into oestradiol through a process called aromatisation.

Blood levels of testosterone in women are roughly one-tenth of those found in men, but the hormone's role is no less significant. It acts on androgen receptors found in the brain, bones, muscles, cardiovascular system, and genital tissue. When those receptors are inadequately stimulated, systems that depend on them begin to underperform.

What Happens When Female Testosterone Drops

Testosterone levels in women begin declining in the late twenties and continue to fall steadily through the thirties and forties. By the time menopause arrives, circulating testosterone may be half of what it was at its peak. Surgical menopause, where the ovaries are removed, causes an even more dramatic and immediate drop.

The clinical picture of low testosterone in women can include:

• Persistent fatigue that does not respond to sleep or lifestyle changes
• Reduced libido or complete loss of sexual desire
• Difficulty with arousal and decreased sensitivity
• Low mood, irritability, or a vague sense of "flatness"
• Cognitive fog, particularly difficulty with word-finding and concentration
• Loss of lean muscle mass and increased central body fat
• Reduced bone mineral density

These symptoms overlap with oestrogen deficiency, depression, thyroid dysfunction, and simple burnout. This overlap is precisely why testosterone is so often overlooked. Clinicians may attribute the full picture to oestrogen loss and prescribe oestrogen-only or combined oestrogen-progesterone therapy, missing the androgen piece entirely.

The Clinical Case for Female Testosterone Therapy

The strongest body of evidence for testosterone therapy in women relates to hypoactive sexual desire disorder, a condition characterised by persistently low sexual desire that causes personal distress. Multiple randomised controlled trials have demonstrated that transdermal testosterone, delivered through creams or patches, meaningfully improves desire, arousal, and sexual satisfaction in postmenopausal women.

But sexual health is only one dimension. Clinical experience and emerging research point to broader benefits:

• Energy and vitality. Many women report significant improvements in physical and mental energy within weeks of starting physiological-dose testosterone.
• Mood regulation. Testosterone influences serotonin and dopamine pathways. Restoring levels to the normal premenopausal range may help stabilise mood in women who have not fully responded to oestrogen therapy alone.
• Musculoskeletal health. Testosterone supports muscle protein synthesis and bone remodelling. This matters enormously as women age and osteoporosis risk climbs.
• Cognitive function. Androgen receptors are abundant in brain regions associated with memory and executive function. While large-scale cognitive outcome data are still maturing, the mechanistic rationale is strong.

The key principle is physiological dosing. The goal is to restore testosterone to the normal premenopausal range, not to push it into supraphysiological territory. At appropriate doses, the side effect profile is remarkably favourable.

Why the Conversation Has Lagged Behind the Evidence

Several factors explain why testosterone therapy for women remains under-prescribed. First, no major pharmaceutical company has brought a female-specific testosterone product to market in most countries, which means there is limited commercial incentive to fund large trials or educate prescribers. Most testosterone preparations used for women are either compounded or adapted from male formulations at lower doses.

Second, the shadow of the Women's Health Initiative, a large trial from the early 2000s that raised concerns about combined hormone therapy, made many clinicians and patients broadly cautious about any form of hormonal treatment. Although that trial did not even study testosterone, the resulting cultural hesitancy affected the entire field of female endocrinology.

Third, there is a knowledge gap in medical training. Many physicians receive minimal education on androgen physiology in women, which means they may not think to measure testosterone or consider it as part of a hormone therapy regimen.

How Testosterone Is Prescribed for Women

When testosterone therapy is appropriate, transdermal application is the preferred route. Oral testosterone is generally avoided because first-pass liver metabolism can alter lipid profiles unfavourably. Creams and gels applied to the skin allow for steady absorption and predictable blood levels.

A typical approach involves:

• Baseline blood work. Total testosterone, free testosterone, and sex hormone-binding globulin (SHBG) are measured alongside a standard hormone panel.
• Starting dose. A low dose is initiated, usually around one-tenth of the standard male dose.
• Monitoring. Blood levels are rechecked at six to twelve weeks, and the dose is adjusted to keep testosterone within the physiological female range.
• Ongoing review. Symptoms, side effects, and blood markers are reassessed regularly.

Potential side effects at physiological doses are uncommon but can include acne, mild facial hair growth, and oily skin. These are typically dose-dependent and reversible. At supraphysiological doses, more significant virilising effects can occur, which is why careful monitoring and appropriate prescribing are essential.

Who Should Consider Testing

Not every woman needs testosterone therapy, but many would benefit from at least having their levels checked. Testing is particularly worth considering for women who:

• Are postmenopausal or have had their ovaries removed
• Experience persistent low libido despite adequate oestrogen therapy
• Report unexplained fatigue, mood changes, or cognitive difficulties
• Are on oral oestrogen or hormonal contraceptives, which raise SHBG and can lower free testosterone
• Are in their late thirties or forties with symptoms suggestive of early androgen decline

A single blood test is not definitive. Testosterone levels fluctuate throughout the day and across the menstrual cycle. Clinical interpretation requires correlating the numbers with symptoms, medical history, and other hormonal markers.

The Role of Telehealth in Hormone Assessment

Hormone health is an area where telehealth can add real value. Initial consultations, symptom assessment, blood test ordering, and follow-up reviews all lend themselves well to remote care. For women who have struggled to get their concerns heard in brief face-to-face appointments, a dedicated telehealth consultation focused on hormonal health can be a practical next step.

That said, telehealth works best as part of a broader care framework. Complex cases, women with contraindications to hormone therapy, or those with significant comorbidities should have input from an in-person specialist. The goal is always integrated, patient-centred care.

Moving the Conversation Forward

Testosterone is not a fringe hormone for women. It is a fundamental part of female physiology that deserves the same clinical respect given to oestrogen and progesterone. The evidence base is growing, clinical guidelines from international menopause societies now endorse its use for specific indications, and more clinicians are becoming comfortable prescribing it.

If you are experiencing symptoms that could relate to low testosterone, the most important step is to have the conversation with a qualified physician who understands female hormone health. Ask for testing, discuss the results in context, and make an informed decision together.
