Testosterone for perimenopause: the hormone nobody tests

Wait, women have testosterone?

Yes, and not a trivial amount. Before menopause, your ovaries and adrenal glands produce testosterone every day. Measured in the blood, you actually carry more testosterone than estrogen for most of your adult life. It just gets branded as "the male hormone," so it never comes up at your appointments.

In women, testosterone contributes to:

• Sexual desire, the spontaneous "I want to" kind
• Muscle mass and strength
• Bone density
• Energy and motivation
• Mood and mental sharpness (likely, though the research here is thinner than the internet suggests)

What happens to it in perimenopause

Here's the part that surprises people: testosterone doesn't crash at menopause the way estrogen does. It declines slowly with age, starting in your 20s. By your 40s, you're producing roughly half of what you made at your peak.

So while your estrogen is doing its perimenopause rollercoaster impression (see Which hormone is causing which perimenopause symptom for the full map), your testosterone has been quietly walking downstairs for two decades. The two changes stack. That combination is one reason your 40s can feel so different from your 30s, even before your periods change.

What the evidence actually supports

This is where PeriSlayer gives it to you straight, because the internet will happily sell you testosterone for everything from wrinkles to your personality.

Strong evidence: low sexual desire. The 2019 Global Consensus Position Statement, backed by menopause societies around the world, concluded that low dose transdermal testosterone (cream or gel on the skin) can help women whose sexual desire has dropped in a way that genuinely bothers them. Clinicians call this hypoactive sexual desire disorder, or HSDD. This is the one use with solid trial data behind it.

Weak or unproven so far: everything else. Energy, mood, brain fog, muscle, bone. Plenty of women report improvements, and researchers are actively studying these, but the trials done so far haven't proven benefits beyond desire. That doesn't mean it's false. It means "we don't know yet," which is an answer women's health gives us constantly, because the research simply hasn't been funded. (We wrote a whole article about that gap.)

Why nobody offers it

A few overlapping reasons:

1. No FDA approved product for women exists in the US. Every prescription is off label, which makes many doctors hesitant. Australia approved a testosterone cream for women, and in the UK, NHS prescribing of testosterone gel for women over 40 has grown around 15 fold in under a decade. The US is behind.
2. Most doctors got almost no menopause training. If they didn't learn to manage estrogen, testosterone was definitely not in the curriculum.
3. The blood test problem. Standard testosterone tests were designed for male ranges and are unreliable at the low levels women have. And your level doesn't predict your symptoms well anyway, which is why guidelines say the decision should be based on symptoms, not a lab number. A blood test is still used before and during treatment, but mainly to avoid overdosing, not to diagnose you.

What treatment actually looks like

If you and a clinician decide to try it, the evidence backed version looks like this:

• A cream or gel on the skin, at roughly one tenth of the standard male dose. In practice that often means a small pea sized amount daily, or a fraction of a male product sachet.
• A baseline blood test first, then follow up testing to keep your level in the normal female range.
• A fair trial of about three to six months, then an honest reassessment. If nothing improved, guidelines say stop.
• Often alongside estrogen and progesterone, not instead of them. If you're new to that conversation, start with HRT for perimenopause: a straight-talking guide.

What to skip: pellets and injections. Implanted pellets and injectable testosterone regularly push women's levels far above the normal female range, and you can't remove a pellet once it's in. Guidelines specifically recommend against them. If a med spa is offering you pellets with a side of IV vitamins, walk out with your wallet intact.

Side effects to know about: at proper female doses, the main ones are acne and extra hair growth where you apply it (rotating the application spot helps). At excessive doses, think pellets, you risk voice changes and hair loss that don't reverse. Dose matters. A lot.

What to ask your doctor, by name

Walk in with this script:

• "My sexual desire has dropped and it's distressing me. I'd like to discuss transdermal testosterone, consistent with the Global Consensus Position Statement on testosterone for women."
• "Can we check a baseline total testosterone level and monitor it during treatment to keep me in the female range?"
• "If you don't prescribe it, can you refer me to a menopause trained clinician who does?"

If you get told no without a real conversation, that's familiar territory. Told you do not qualify for HRT? covers how to handle a dismissive appointment, and most of it applies here too. If you are still weighing how the hormones themselves get into you, Estrogen patch vs gel vs pill explains why the route matters.

And while you're building the full picture: strength training is the other half of the muscle and energy story at this age. Perimenopause and exercise explains why lifting heavy things matters more now than ever, no prescription required. If a supplement aisle promised you the same results, Perimenopause supplements: what works and what doesn't sorts the evidence from the marketing.

The bottom line

Testosterone is a real, legitimate part of the perimenopause conversation, with genuinely good evidence for one thing (desire) and a lot of hopeful maybes for the rest. It is not a miracle, it is not dangerous when dosed properly, and it is not something you should have to discover from an app instead of your doctor.
