The Overlooked Hormone
Testosterone Therapy for Women: Why It Matters
Testosterone is often labeled a male hormone, but it plays a meaningful role in women's health across the lifespan. Women naturally produce testosterone in the ovaries and adrenal glands, and levels decline with age, well before menopause. In a 1995 study of 33 regularly cycling women, the expected testosterone level at age 40 was about half that at age 21.
For some women, that decline coincides with changes that can be hard to pin down: flagging energy, low libido, mental fog, or a general sense that something is off despite normal thyroid and estrogen labs. Testosterone therapy for women is a physician-supervised treatment whose best-supported use is narrower than that list: low sexual desire that causes distress after menopause.
At Protocol Health in Scarsdale, NY, we treat testosterone as one part of a broader hormonal picture, never in isolation. This guide walks through how it works, who may benefit, and what thoughtful, individualized care actually looks like.

What is testosterone therapy for women?
Testosterone therapy for women is the physician-supervised use of low-dose testosterone, most commonly a compounded cream applied to the skin, mainly to treat low sexual desire that causes distress in postmenopausal women. Energy and wellbeing are sometimes discussed, but the trial evidence does not establish a benefit there.
Doses used in women are a small fraction of male doses, aimed at restoring levels toward the range typical of a healthy younger woman rather than exceeding it. Treatment is guided by symptoms, with blood levels checked to set a baseline and to keep levels within the normal female range, and reassessed over time.
It is not a one-size-fits-all prescription or a shortcut. Suitability is determined case by case after a consultation, a review of your history, and appropriate bloodwork.
The Mechanism
How does testosterone therapy work in women?
Testosterone therapy works in women by gently supporting low testosterone toward a physiologic range, where it acts on receptors across the body. Testosterone is an androgen that interacts with receptors throughout the body, including the brain, muscle, bone, skin, and tissues involved in sexual response. When levels fall below what your body is accustomed to, some women notice downstream effects on mood, drive, and vitality.
Low-dose therapy is intended to gently support testosterone toward a physiologic range. A daily transdermal cream is the most common delivery method for women because it allows precise, adjustable dosing and steady absorption. Some providers use other approaches, but creams are often favored for their fine control.
Because hormones work as a connected system, testosterone is rarely considered alone. Estrogen, progesterone, thyroid, and metabolic markers all inform the plan, which is why comprehensive testing matters before starting.
The Benefits
What benefits may women experience?
The main benefit women may experience is relief of low sexual desire that causes distress, which is the most established use of testosterone in women, particularly after menopause. Research suggests low-dose testosterone may support improvements in libido, arousal, and sexual satisfaction in appropriately selected women.
Beyond sexual health, some patients report better energy, mood or motivation, but randomized trials have not shown consistent benefit for wellbeing, cognition, muscle or bone. Protocol Health does not prescribe testosterone for those reasons alone, and we set realistic expectations rather than promise outcomes.
Because low libido overlaps with relationship, mood, medication and other causes, benefits are best evaluated over a few months alongside repeat labs, not judged in the first few days.
Candidacy
Who is a candidate for testosterone therapy?
A candidate for testosterone therapy is typically a woman, often in perimenopause or menopause, who has persistent, distressing low sexual desire that is not explained by other treatable causes. There is no blood testosterone level that diagnoses the problem; labs are used to exclude other causes and to set a baseline before treatment.
A thorough evaluation also screens for factors that may make therapy inappropriate, including pregnancy, breastfeeding, certain hormone-sensitive conditions, or a history that warrants caution. This is exactly why care must be physician-led and individualized.
If you are unsure whether your symptoms point to hormones, a structured evaluation like Protocol Health's Female Hormone and Longevity Assessment can help clarify the picture before any treatment decision is made.
Safety First
Is testosterone therapy for women safe? Side effects to know
The safety profile of testosterone therapy for women is generally good when it is dosed conservatively and monitored: it is well tolerated in many women, but it has side effects to know. The goal is always to keep levels within a normal physiologic range, which helps limit the risk of side effects.
Potential side effects are usually dose-related and often reversible with adjustment. They can include acne, increased facial or body hair, or oily skin; higher-than-intended levels can cause more significant changes, which is why monitoring matters. Application-site transfer to partners or children can be minimized with proper technique.
Ongoing lab monitoring lets your provider fine-tune the dose and catch any concerns early. This information is educational and not medical advice; the right and safe approach for you can only be determined with a qualified provider who knows your full history.
The Evidence
What does the research say about testosterone for women?
The research on testosterone for women is clearest on one question: low sexual desire after menopause. A 2019 systematic review and meta-analysis in The Lancet Diabetes & Endocrinology pooled 36 randomized controlled trials with 8,480 participants. In postmenopausal women, testosterone improved sexual desire, arousal, pleasure, orgasm and the frequency of satisfying sexual events, and reduced sexual distress, compared with placebo or a comparator. The authors concluded testosterone is effective for postmenopausal women with low sexual desire causing distress.
The same meta-analysis is also the clearest guide to the trade-offs. Testosterone taken by mouth raised LDL cholesterol, while transdermal patches and creams did not, which is why the authors preferred non-oral routes. Acne and hair growth were more likely with testosterone, no serious adverse events were recorded, and no effects were found on body composition, muscle and bone, or cognition, although few women contributed data on those outcomes. Long-term safety still needs more study.
Professional societies have converged on the same reading. The Global Consensus Position Statement on the Use of Testosterone Therapy for Women, published in 2019, was endorsed by bodies including the Endocrine Society, The North American Menopause Society, the International Menopause Society and the Royal College of Obstetricians and Gynaecologists. In the United States no testosterone product is FDA-approved specifically for women, so testosterone for women is prescribed off-label, which is one more reason it belongs under physician supervision with lab monitoring.
The Process
What to expect at Protocol Health
At Protocol Health, expect care to begin with a consultation and comprehensive lab work, a full hormone panel that looks at testosterone in the context of estrogen, progesterone, thyroid, and metabolic health. This lab-informed foundation is what separates thoughtful treatment from guesswork.
If therapy is appropriate, your physician typically starts with a conservative dose of a compounded cream and sets a follow-up schedule. Compounded testosterone cream is not an FDA-approved product; it is prepared by a pharmacy for the individual prescription. Levels and symptoms are reviewed, and the plan is adjusted with the goal of keeping you on the lowest effective dose.
In-person visits are at our Scarsdale clinic, and telehealth care is available in NY, NJ, CT, FL, and CA, with the same real clinical team behind every step.

FAQ
Frequently Asked Questions
How is testosterone dosing for women different from men?
Women use only a small fraction of the testosterone doses used in men. The goal is to restore levels toward the range of a healthy younger woman, not to exceed it. This is why low-dose, carefully monitored delivery methods like compounded creams are often preferred, and why physician supervision is essential.
How long does it take to notice results from testosterone therapy?
Responses vary from person to person. Some women notice a change in sexual desire within several weeks, but a fair evaluation usually takes a few months alongside repeat lab work, and the 2019 global consensus statement advises stopping treatment that has not helped by six months. Because symptoms overlap with other conditions, results are best judged over time rather than in the first days.
Will testosterone therapy cause unwanted hair growth or a deeper voice?
Side effects like acne or increased facial hair are typically dose-related and often reversible when the dose is adjusted. Significant changes such as voice deepening are associated with excessive levels, which is precisely what conservative dosing and regular monitoring are designed to help prevent. Your provider tailors and monitors the plan to your labs.
Do I need lab tests before starting testosterone therapy?
Yes. Responsible care begins with comprehensive bloodwork that evaluates testosterone alongside estrogen, progesterone, thyroid, and metabolic markers. No blood level diagnoses low testosterone in women, so labs are used to rule out other causes and establish a baseline for safe, individualized dosing and follow-up.
Can testosterone therapy help with menopause symptoms?
Testosterone can improve low sexual desire in some postmenopausal women; it does not treat hot flashes, and it is often considered as part of a broader hormone optimization plan that can include estrogen and progesterone. Whether it is right for you depends on your symptoms, history, and labs, evaluated with a physician.
Is testosterone therapy for women available through telehealth?
Yes. At Protocol Health, hormone care can be coordinated in person in Scarsdale or via telehealth across NY, NJ, CT, FL, and CA. Lab work is arranged so your physician can build and monitor an individualized plan wherever you are.
