Testosterone for Women: The Most Underprescribed Hormone in Medicine

Ask most people which hormone matters for women, and they will say estrogen. Ask about testosterone, and many will think of it as a male hormone, irrelevant or even undesirable for women. This understanding is wrong, and the consequences of that misunderstanding are significant. Testosterone is essential for women’s health, women produce and depend on it throughout their lives, and its decline with age contributes to symptoms that affect a large number of women, symptoms that often go untreated because the role of testosterone is so widely overlooked.

Testosterone for women may be the most underprescribed hormone in modern medicine. There is no FDA-approved testosterone product designed for women in the United States, most physicians are not trained in its use for women, and the cultural framing of testosterone as a male hormone creates hesitation on all sides. Meanwhile, women who could benefit, women with low libido, persistent fatigue, low mood, and a diminished sense of vitality, go without a treatment that could meaningfully improve their lives.

This article explains what testosterone does in women’s bodies, what happens when it declines, who might benefit from treatment, how it is done safely, and why it remains so underused. If you are a woman who has noticed a loss of desire, drive, energy, or vitality, particularly if hormone treatment focused only on estrogen has not fully addressed how you feel, this is written for you.

What testosterone does in women’s bodies

Testosterone is not a male hormone that women happen to have a little of; it is an essential hormone for women, present and active throughout a woman’s life, with important roles in multiple systems. Women produce testosterone in the ovaries and adrenal glands, and while the amounts are smaller than in men, the hormone is no less important to female physiology.

In terms of sexual health, testosterone is central to libido, the fundamental drive and interest in sex. It also contributes to sexual arousal, sensation, and the capacity for satisfying sexual response. For women, testosterone is arguably the most important hormone for desire specifically, more directly connected to libido than estrogen. When testosterone is low, desire often diminishes, sometimes to the point of disappearing.

Beyond sexual health, testosterone contributes to energy and vitality, the sense of drive and get-up-and-go that makes a person feel capable and engaged. It affects mood, with low levels contributing to low mood, diminished motivation, and a flattened sense of wellbeing. It plays a role in cognitive function, including aspects of mental clarity and focus. It contributes to muscle mass and strength, and to bone density. And it affects the overall sense of vitality and confidence that is harder to measure but real to experience.

The breadth of testosterone’s roles means that when it declines, the effects are not limited to sexual health, though that is often the most noticed. Women with low testosterone may experience a constellation of symptoms across desire, energy, mood, and vitality, a general sense that something has diminished, that they have lost a part of their drive and engagement with life.

What happens when testosterone declines

Testosterone in women declines with age, and understanding this trajectory helps explain the symptoms that emerge. Female testosterone levels peak in the 20s and decline gradually thereafter, so that by the time a woman reaches her 40s, her testosterone is often substantially lower than it was two decades earlier, and it continues to decline with age.

This decline is gradual rather than abrupt, unlike the relatively sudden drop in estrogen at menopause. But the cumulative effect over the decades is significant, and by the perimenopausal, menopausal, and postmenopausal years, many women have quite low testosterone levels. Certain situations accelerate the decline further, including removal of the ovaries, which eliminates a major source of testosterone production, and certain medications and conditions.

The symptoms of low testosterone in women reflect the hormone’s many roles. Reduced sexual desire is often the most prominent and the most likely to prompt a woman to seek help, though even this is frequently dismissed or attributed solely to estrogen or to psychological factors. Diminished sexual arousal, sensation, and satisfaction often accompany the reduced desire. Persistent fatigue and low energy that do not resolve with rest are common. Low mood, reduced motivation, and a flattened emotional experience occur. A general loss of vitality, drive, and the sense of engagement with life is often described, sometimes as simply not feeling like oneself. Reduced muscle tone and strength, and effects on bone density over time, also occur.

Because these symptoms overlap with those of other conditions, including estrogen deficiency, thyroid dysfunction, depression, and the general effects of poor sleep or stress, low testosterone is easily missed or attributed to something else. A woman reporting low libido, fatigue, and low mood might be evaluated for depression, prescribed an antidepressant, or simply told that these are normal parts of aging, without anyone measuring or considering her testosterone. This is precisely the gap that leaves so many women untreated.

The evidence and the underprescription problem

The evidence supporting testosterone for women, particularly for sexual desire, is stronger than the treatment’s rare use would suggest. Clinical studies have demonstrated that appropriate testosterone supplementation improves sexual desire, arousal, and satisfaction in women with low levels and associated symptoms. The strongest evidence is for the effect on sexual desire, but clinical experience also supports benefits for energy, mood, and overall vitality in many women.

Despite this evidence, testosterone remains dramatically underprescribed for women, for several interlocking reasons. The absence of an FDA-approved testosterone product designed for women in the United States is a major factor. Because no product is specifically approved and dosed for women, prescribing testosterone for women requires using products designed for men at appropriately reduced doses, or using compounded preparations formulated for women. This off-label prescribing requires knowledge, comfort, and willingness that many physicians lack.

The cultural framing of testosterone as a male hormone creates hesitation among both patients and clinicians. The idea of a woman taking testosterone can trigger unfounded fears of masculinization or the sense that it is somehow inappropriate, when in fact the goal is simply to restore testosterone to the normal range for a healthy woman, not to raise it to male levels.

The knowledge gap in medical training means many physicians were never taught to consider testosterone in women, to recognize the symptoms of low testosterone, to measure it appropriately, or to prescribe and monitor it. It falls outside the scope of what conventional training emphasized.

And the general dismissal of women’s concerns about libido, energy, and vitality, particularly in midlife and beyond, means the symptoms that might prompt testosterone evaluation are often not taken seriously in the first place.

The result is a treatment supported by evidence, capable of meaningfully helping many women, that is rarely offered. Our page on testosterone for women reflects our view that this gap represents a real failure of care, and that women deserve access to this option with appropriate evaluation and monitoring.

Who might benefit from testosterone

Testosterone is worth considering for women with symptoms consistent with low testosterone, particularly when those symptoms are not fully explained or addressed by other factors. Several groups are especially likely to benefit.

Women with low sexual desire that is distressing to them. This is the most established application, supported by the strongest evidence. A woman whose libido has diminished, particularly if the change is significant and troubling to her, may benefit from testosterone evaluation and treatment. This applies across the reproductive stages but is especially relevant in perimenopause, menopause, and beyond, when testosterone levels are often low. Our article on libido after 60 discusses this in the context of postmenopausal sexual health.

Women on estrogen therapy who still do not feel like themselves. A woman receiving hormone replacement focused on estrogen and progesterone may find that while some symptoms improve, she still experiences low libido, fatigue, or diminished vitality. Testosterone is often the missing piece, addressing the dimensions that estrogen does not. Comprehensive bioidentical hormone care considers testosterone as part of the full hormonal picture rather than focusing on estrogen alone.

Women who have had their ovaries removed. Surgical removal of the ovaries eliminates a major source of testosterone production, and these women often experience a significant drop in testosterone and associated symptoms. They are frequently good candidates for testosterone evaluation.

Women with persistent fatigue, low mood, and diminished vitality not explained by other causes. While these symptoms have many possible causes and require comprehensive evaluation, low testosterone is one contributor that is frequently overlooked, and for some women addressing it makes a meaningful difference. This connects to the broader picture discussed in our articles on perimenopause and cognitive symptoms and the cortisol-perimenopause cascade.

The common thread is that women experiencing the symptoms of low testosterone deserve to have it considered, measured, and treated when appropriate, rather than having those symptoms dismissed or attributed solely to other causes without testosterone ever entering the conversation.

How testosterone for women is done safely

Testosterone therapy for women, done correctly, is about restoring testosterone to the normal physiological range for a healthy woman, using low doses with appropriate monitoring. This is fundamentally different from the higher-dose testosterone therapy used in men, and understanding the approach addresses many of the fears that surround it.

The goal is physiological restoration, bringing testosterone from a low level up to the range appropriate for a healthy younger woman. It is not about exceeding that range or achieving male-typical levels. The doses used are small, calibrated to female physiology, and the aim is to relieve the symptoms of deficiency by correcting the deficiency, not to push levels higher than natural.

Appropriate evaluation precedes treatment. This includes measuring testosterone levels, total and free, along with related hormones and markers, and taking a careful symptom history. Understanding a woman’s baseline and her symptom picture guides whether testosterone is appropriate and how to dose it. Our advanced labs service provides the comprehensive assessment that this requires.

Monitoring during treatment ensures that levels are brought into the appropriate range and not beyond, and that the woman is responding well without unwanted effects. Testosterone levels are rechecked, symptoms are assessed, and dosing is adjusted to optimize benefit while keeping levels physiological. This ongoing monitoring is part of responsible testosterone therapy and part of what distinguishes careful clinical care from casual prescribing.

When done this way, with appropriate dosing and monitoring, unwanted effects are uncommon, and the fears of masculinization that deter many women are largely unfounded at physiological doses. The occasional effects that can occur with excessive dosing are avoided by keeping levels in the appropriate range, which is precisely what careful monitoring accomplishes. The result for appropriate patients is relief of the symptoms of deficiency, improved desire, energy, mood, and vitality, without the woman being pushed outside her natural physiological range.

What to expect from treatment

Women who begin testosterone therapy for appropriate indications often experience meaningful improvement, though the timeline is gradual and individual.

The effects develop over weeks to a few months rather than immediately. Testosterone works gradually, and the improvements in desire, energy, mood, and vitality emerge over time as levels are optimized. Expecting an immediate transformation and abandoning treatment too soon is a mistake; the benefits accrue over the first months.

The improvement in sexual desire is often the most noticed, consistent with the strong evidence for this effect. Women who had experienced a troubling loss of libido frequently find that desire returns as testosterone is restored. The improvements in energy, mood, and overall vitality, while harder to measure, are meaningful to many women, who describe feeling more like themselves, more engaged, more capable of drive and enthusiasm.

Optimization takes some adjustment. Finding the right dose for an individual woman, the dose that relieves symptoms while keeping levels physiological, may require some adjustment based on levels and response. This is a normal part of the process, and it is why monitoring and communication matter.

The women who do best engage with the evaluation, give treatment appropriate time to work, communicate about their response so that dosing can be optimized, and understand that testosterone is often one part of comprehensive hormonal care rather than a single fix. For many women, restoring testosterone addresses a dimension of wellbeing that estrogen-focused treatment left untouched, and the difference in how they feel is significant.

Testosterone as part of comprehensive care

Testosterone is rarely the whole story; it is usually one part of comprehensive attention to a woman’s hormonal health and overall wellbeing. Understanding how it fits into the larger picture matters for getting the best results.

For many women, testosterone works alongside estrogen and progesterone. The hormone replacement therapy that addresses estrogen deficiency, treating hot flashes, supporting mood and sleep, and maintaining various aspects of health, is complemented by testosterone addressing desire, energy, and vitality. Together, comprehensive hormonal restoration addresses the full picture rather than one hormone in isolation. Our bioidentical hormone approach considers all the relevant hormones for each woman.

For sexual health specifically, testosterone addresses desire while other interventions address other dimensions. Vaginal estrogen addresses the physical comfort of the genital tissues, ensuring that sex is not painful, while testosterone addresses the desire itself. For some women, PT-141 adds another avenue to desire through brain pathways. Comprehensive sexual health care combines these appropriately, as discussed in our article on libido after menopause.

And testosterone fits within attention to overall health, energy, sleep, mood, and vitality. Sometimes low testosterone is one contributor among several to how a woman feels, and comprehensive care addresses the others as well, the thyroid, the adrenal and stress picture, sleep, and lifestyle, as relevant. The goal is not to treat a number but to help a woman feel well, and testosterone is one important tool toward that goal.
