Testosterone in Women: What It Does and Why It's Yours

Do women even have testosterone?

Yes, and not some trace amount either. Here is the bit that deserves a proper pause. Testosterone is not a male hormone at all. It is a human one, sitting in every single body, men and women alike. We simply slapped a blue label on it a long time ago and stopped asking questions. We did exactly the same to estrogen, which men carry too, by the way. The labels were never the science.

And then there is this. Your body makes testosterone in the ovaries and the adrenal glands, and across much of your adult life you produce several times more of it than estrogen. Read that again, because it is genuinely startling. The hormone you were told belonged to men? You have quietly been out-producing your own estrogen with it for decades. It is part of the standard female toolkit, not some masculine intruder that wandered in by mistake.

So the notion that testosterone is a male hormone is probably the most complete misunderstanding of the three hormones we cover. It is yours. It always was. Nobody just thought it worth mentioning.

What does testosterone do in women?

More than its reputation suggests. Testosterone feeds sexual desire, yes, but also your energy, your motivation, your muscle and bone strength, your mood, and a certain mental sharpness. Think of it as part of your engine, the drive underneath the drive.

When it is present in the right amount, you barely notice it, the way you do not notice a smoothly running engine. You notice it when it dips.

What happens to testosterone in perimenopause?

Unlike estrogen, which lurches and swings, testosterone tends to fade slowly and steadily. Its decline actually begins earlier than you would expect, from your 30s onward, and by the time you reach menopause your levels may be roughly half of what they were at their peak. Some of that is the ovaries winding down, the same underlying story as the other hormones.

So this is less a sudden perimenopausal drop and more a long, quiet slide that has been under way for years. Which is part of why it slips past unnoticed. There is no dramatic moment, just a gradual dimming you might reasonably put down to age, or tiredness, or simply the shape of your life.

What are the signs of low testosterone?

The clearest and most studied sign is a genuine loss of sexual desire, the kind that feels like a switch has been turned down rather than just a busy, distracted season. Alongside it, some women notice lower energy, a flatter mood, less motivation, or a loss of muscle tone.

Here I have to be honest with you, because plenty of the internet will not be. Those broader symptoms, the fatigue and the flatness, overlap heavily with low estrogen, with low progesterone, with a genuinely hard year, with simply being worn out. They are real, but they are difficult to pin on testosterone alone. Desire is the symptom most reliably linked to it.

Can you take testosterone for it?

You can, and this is exactly where I want to steer you carefully, because testosterone has become the internet's favourite miracle supplement lately, and the evidence is far more modest than the noise.

Here is what the research actually supports. For women after menopause with distressing low sexual desire, testosterone therapy can genuinely help, and the major medical societies endorse it for precisely that. What the evidence does not support, at least not yet, is testosterone as a general fix for energy, mood, or vitality. Taking it hoping to feel switched back on across the board is running well ahead of the science.

There are practical wrinkles too. In many countries there is no testosterone product licensed for women at all, so doctors adapt male formulations at much smaller doses, and estrogen is usually settled first. All of which is to say, this is a real conversation for you and a knowledgeable doctor, not something to order on a hunch. We covered the wider hormone therapy picture in this piece.

Sorting out which of your three hormones is behind what you are feeling is genuinely hard, precisely because their symptoms overlap so much. That is the tangle Stree Sense is built to help with. A companion that tracks the pattern over time, so “is this testosterone, or estrogen, or just a brutal few months” slowly becomes a question you can actually answer with evidence, rather than a shrug.

And the reframe worth holding onto is this. Testosterone is not something you are simply losing to age like a defeat. It is part of your drive, your appetite for life, your spark, and it was always yours. Understanding it is how you stop mistaking a quiet, often correctable dip for the person you have become. These years can carry as much fire as any that came before, once you know what you are working with.
