The Conversation Testosterone Was Never Allowed to Have With Women

There is a peculiar irony in how medicine has framed testosterone for women: as a hormone that belongs to the other side of a biological divide, something to be tolerated in small amounts but never truly considered. For decades, conversations about female hormonal health have centered almost entirely on estrogen and progesterone — and for good reason. But in doing so, we've left out a third player that turns out to be rather important. Testosterone, it seems, has had things to say about women's health for a long time. We simply weren't in the habit of listening.

What Testosterone Actually Does in the Female Body

Women produce testosterone — primarily in the ovaries and adrenal glands — at concentrations roughly ten times lower than men, but the receptor sensitivity that amplifies its effects means those smaller amounts carry significant biological weight. Testosterone in women is associated with skeletal muscle maintenance, bone density, cognitive sharpness, libido, mood regulation, and the general sense of physical agency that makes a person feel like themselves. It is not a secondary hormone. It is a foundational one.

The decline begins earlier than most people expect. Testosterone levels in women start falling gradually through the late 20s and 30s, and by the time a woman reaches her 40s — well before menopause in many cases — she may be operating at a fraction of her earlier levels. What follows is often a cluster of symptoms that are individually unremarkable and collectively easy to dismiss: fatigue that sleep doesn't resolve, a subtle erosion of motivation, decreased strength despite consistent effort, and a libido that has quietly exited the building. Because these changes accumulate slowly, they tend to be absorbed into the ambient noise of a busy life rather than recognized as a coherent hormonal signal.

"Most people attribute these changes to 'just getting older.' Most people are wrong."

The Evidence Has Been Building

What's changed in recent years isn't the biology — it's the willingness to study it seriously. A 2022 review by Donovitz found that testosterone therapy in women was associated with improvements in sexual function, mood, energy, and musculoskeletal health, with a favorable safety profile when appropriately dosed and monitored (Donovitz, 2022). More recently, a 2025 position statement from the Latin American Association of Gynecological Endocrinology formalized clinical guidance around androgen therapy for midlife and older women, reflecting a growing consensus that this is a legitimate and underutilized area of care (Pilnik et al., 2025).

This isn't fringe thinking. It's the scientific community catching up to what many women have been describing for years — a form of vitality loss that didn't fit neatly into the estrogen-and-progesterone narrative they were offered.

The reasons it took this long are worth acknowledging. Research funding, historical framing of testosterone as a "male" concern, and a lingering cultural discomfort with women reporting reduced libido as a medical issue — rather than a lifestyle one — all played a role. But the conversation is shifting, and the shift matters.

What Thoughtful Assessment Looks Like

The most important thing to understand about testosterone in women is that there is no universal threshold that defines sufficiency. Hormone levels must be interpreted in context: against a woman's baseline, her symptoms, her age, her other hormonal markers, and the broader picture of her metabolic and endocrine health. A number that looks "normal" on a standard lab panel may be well below what is optimal for a particular individual.

This is why the assessment process matters as much as the intervention itself. A genuinely useful evaluation would consider:

• Total and free testosterone, not just total (free testosterone is the biologically active fraction)
• SHBG (sex hormone-binding globulin), which affects how much testosterone is actually available to tissues
• DHEA-S, the adrenal precursor that feeds into testosterone production
• Estradiol and progesterone, because no hormone exists in isolation
• Thyroid markers and cortisol, because hormonal systems interact in ways that make tunnel vision counterproductive

What this kind of assessment reveals, more often than not, is a picture more nuanced than any single number could capture. Hormones are less like switches and more like instruments in an ensemble — and the goal is harmony across the whole, not just tuning one string.

There is something quietly significant about a woman arriving at midlife with a clear, data-informed understanding of what her hormones are actually doing — rather than a vague sense that something has shifted and an equally vague reassurance that this is simply what getting older feels like. The biology was always there. The conversation, finally, is beginning to match it.
