The conversation about testosterone therapy for women is one of the most under-served clinical conversations in mid-life medicine. I see this constantly: a 47-year-old woman comes in with low libido, brain fog, dwindling motivation, and a body that no longer responds to the workouts that used to work. She has been to her primary care provider, who ran a TSH and a CBC, told her everything looked normal, and offered an SSRI. No one ever pulled her free testosterone. No one explained that testosterone is not just a male hormone, that women produce it in the ovaries and adrenals across their entire lives, and that declining levels are a recognizable and treatable cause of the cluster of symptoms she just described.
This article is the conversation I have with that patient when she finally lands in my office. It is what I want every woman over 35 to know before she decides whether testosterone therapy is the right next step for her.
Why women have testosterone in the first place — and why it matters
Women produce testosterone in two places: roughly half from the ovaries (as direct testosterone and as androstenedione that converts peripherally) and roughly half from the adrenal glands (largely as DHEA, which converts to testosterone in target tissues). The total female testosterone level is about a tenth of the male level — which sounds small until you realize that the receptor density and the physiological role of androgens in female tissue is significant.
Testosterone in women does several things that nothing else does. It maintains libido — both spontaneous desire and arousal responsiveness. It supports lean muscle mass and bone density. It contributes to baseline energy, motivation, and the sense of "drive" that patients describe losing in mid-life. It influences mood and cognitive sharpness. It keeps the clitoral and vulvar tissue responsive. When testosterone declines — and it begins declining in the late 20s, with a roughly 50 percent reduction by the time most women reach 50 — the symptoms that result are not vague. They are specific, measurable, and consistently described by patients across the women's hormone panels I review.
The decline is usually steady rather than dramatic, which is part of why it gets missed. There is no single moment a woman wakes up testosterone-deficient. She gradually notices that the things that used to feel automatic — interest in sex, motivation to train, the energy to push through a long day — now require effort. Most women attribute this to age, stress, or motherhood. Some of it is. But a meaningful portion is the hormonal decline itself, and that portion is addressable.
The mechanism — why testosterone optimization actually changes how a patient feels
When I evaluate a woman for testosterone therapy, I am thinking about three layers of the hormone signal: production, bioavailability, and receptor response.
Production. Total testosterone is what the ovaries and adrenals are putting out. The reference range for women in most labs is roughly 15 to 70 ng/dL, but that range was set across all ages including post-menopausal women — meaning the lab will call a 30-year-old woman with a level of 18 ng/dL "normal" when her physiological baseline ten years prior was probably 50 or 60. The reference range describes statistical commonality, not optimal function. I evaluate based on where the patient falls relative to her own physiology and her symptom picture, not just whether she clears the low-end cutoff.
Bioavailability. Total testosterone tells me what is in circulation. Free testosterone tells me what the cells can actually use. The two are linked through SHBG (sex hormone-binding globulin), which tightly binds testosterone and renders it biologically inactive. Women on oral estrogen — whether for birth control or for menopausal symptoms — frequently have markedly elevated SHBG from hepatic first-pass effects, which drives free testosterone down even when total testosterone looks adequate. This is one of the most common patterns I identify in women who have been told their testosterone is "normal" but who are clinically deficient. The fix is sometimes as simple as switching from oral to transdermal estrogen, which lets SHBG normalize and free testosterone rise without any direct testosterone supplementation.
Receptor response. Even with adequate free testosterone, downstream tissues have to be able to respond. Receptor sensitivity is influenced by inflammation, insulin resistance, and chronic cortisol elevation. A woman with high cortisol from chronic stress and high fasting insulin from metabolic dysfunction will respond less to a given testosterone level than a woman with normal cortisol and good insulin sensitivity. This is why I do not treat hormones in isolation from the metabolic picture.
What I look for in the workup
Before I write a single prescription for testosterone therapy in a female patient, comprehensive lab work is non-negotiable. The panel I run includes:
- Full sex hormones: estradiol, progesterone, total testosterone, calculated free testosterone, DHEA-sulfate, SHBG
- Pituitary hormones: FSH, LH (to characterize the menopausal stage)
- Full thyroid: TSH, free T3, free T4, reverse T3, TPO and thyroglobulin antibodies
- Metabolic markers: fasting insulin, HbA1c, fasting glucose, lipid panel, comprehensive metabolic panel, CBC
- Inflammatory and adjacent: hs-CRP, ferritin, vitamin D, B12
When I sit down with the patient at the lab review visit, I am looking for the pattern — not just the testosterone number in isolation. A woman with free testosterone at the low end of normal, SHBG elevated from oral contraceptives, and a cluster of consistent symptoms is a candidate even if the lab does not flag the testosterone as low. A woman with free testosterone at the high end of normal but persistent low libido may have a receptor or vascular problem rather than a hormonal one, and more testosterone will not help her.
I am also screening for what would push me away from testosterone therapy: pregnancy or pregnancy intent, untreated breast or uterine cancer, severe acne or hirsutism that pre-dates the hormone discussion (which suggests an existing androgen excess pattern), and certain cardiovascular conditions where the risk-benefit needs careful individual evaluation.
Not sure where to start?

The treatment options — and how I match the right one to the patient
There is no single right delivery method for female testosterone replacement. The options each have a clinical fit:
Compounded transdermal cream. A custom-dosed cream applied to the inner thigh or labia daily. Allows precise dose adjustment, easy to titrate, easy to discontinue. My most common starting choice for new patients because it gives us the most control during the calibration phase.
Subcutaneous injection. Low-dose testosterone cypionate injected weekly or twice weekly. More predictable serum levels than cream for some patients, useful when absorption through skin has been inconsistent.
Biote pellet therapy. A small pellet implanted subcutaneously every 3 to 5 months that releases testosterone steadily. Convenient — no daily application — and produces remarkably stable levels for the right candidate. The trade-off is that once the pellet is in, the dose is committed for several months. I tend to recommend pellets for established patients whose dose I have already calibrated using cream or injection, rather than as the starting modality.
Hormone optimization for women at our practice usually starts with the lowest reasonable dose, with a six- to eight-week recheck of free testosterone and a symptom inventory. I would much rather start a patient at a dose that produces a soft response and titrate up than start aggressively and create side effects (acne, hirsutism, hair pattern changes, mood changes) that take months to wash out.
This is parallel to how I approach men's testosterone replacement — conservative starting dose, planned recheck, titration based on data and symptom report. The protocol is different, but the philosophy is the same.
What patients notice first, and on what timeline
When the dose is right and the patient is a good candidate, the response timeline is recognizable:
- Weeks 2 to 4: Sleep usually improves first. Energy follows. Some patients describe a return of "drive" — the internal momentum that had been missing.
- Weeks 4 to 8: Mood stabilizes. Cognitive sharpness improves. Libido begins to return for many patients in this window, though the timing is highly variable.
- Months 2 to 3: First lab reassessment. Free testosterone is rechecked, the patient's symptom inventory is reviewed, and the dose is refined. Body composition starts to shift if resistance training is in place.
- Months 3 to 6: Full calibration at the optimized dose. Sexual responsiveness, including clitoral and vulvar tissue sensitivity, often continues improving through this window.
- Months 6 to 12: Sustained optimization. Maintenance cadence is typically a follow-up visit every 6 months with labs.
The patients who do best are the ones who commit to the follow-up cadence. The patients who struggle are usually the ones who feel better at the three-week mark, conclude the work is done, and disengage from the calibration process. The dose that produces initial response is rarely the optimal long-term dose, and getting to optimal requires the data from the recheck.
Where this fits in the broader picture
Testosterone therapy in a woman almost never lives in isolation. Most of the patients I treat are also addressing estrogen and progesterone (which interact with testosterone in important ways), often thyroid, sometimes the metabolic picture, and sometimes the cortisol pattern. The systems are linked, and treating one in isolation tends to underperform compared to treating the system. The hormone health assessment is a useful first step for patients who want to think through their cluster of symptoms before booking.
A meaningful number of the women I see for testosterone are also evaluating GLP-1 therapy for weight that has not responded to anything else. The two interventions often work better in combination than either alone, because hormone optimization restores the metabolic responsiveness that GLP-1 then leverages.
A clear next step
If the symptom cluster I described in the opening sounds like you — declining energy, fading libido, motivation that has dimmed, body composition that no longer responds to your usual training — the most useful next step is a consultation where we pull the full panel and have a real conversation about what your hormonal picture is actually doing.
If you have had recent comprehensive lab work done elsewhere, bring it. If you have only had a TSH and a basic metabolic panel, plan on us ordering the full panel at the first visit. The first appointment is 60 to 90 minutes and covers the history, the symptom inventory, and the lab order. The second appointment is the lab review and the treatment plan conversation, with the data in front of both of us. We see new hormone patients at both the Columbus location and the Warner Robins location; I am at each clinic on a published rotating schedule and the protocol is identical at both. Pick the one that is closer or more convenient and book accordingly.
