Let's get started!

She came in with a thick folder. Lab results from three different providers, a timeline she had typed up herself, and a very specific question: “Why does every panel come back normal when nothing in my body feels normal?”

Her estrogen had been checked. Her progesterone had been checked. Both were in range — which her providers took to mean everything was fine. But no one had checked her testosterone. No one had run a complete thyroid panel. And no one had asked her about libido, energy, motivation, strength, or the feeling she described as “being disconnected from myself.”

Hormone testing in perimenopause and menopause is one of the most nuanced and most frequently mishandled areas of women’s healthcare. This post is your guide to understanding why — and what to ask for.

A Critical Note on Hormone Testing Timing

Before we talk about what to test, let’s talk about when — because this matters enormously.

Hormone levels in perimenopause are not static. They fluctuate significantly, sometimes wildly, even within a single week. What your estrogen reads on Monday may look very different on Thursday. This is why a single hormone panel can be deeply misleading, and why results that come back “normal” don’t always tell the full story.

For premenopausal and perimenopausal women who are still cycling, the most informative time to test is typically Day 19-21 of your cycle (one week after ovulation). This gives you a snapshot of your luteal phase progesterone, which is one of the first hormones to begin declining in perimenopause.

For postmenopausal women or those not cycling, timing is less critical but consistency is essential — test at roughly the same time of day and under similar conditions (fasting, rested) so that results are comparable over time.

The most important takeaway: one panel is a data point, not a diagnosis. Trends over time matter more than any single result.

What a Comprehensive Hormone Panel Looks Like

A thorough hormone evaluation for women in perimenopause and menopause should include:

  • Estradiol (E2) — the primary form of estrogen; expect significant variability in perimenopause
  • Progesterone — often the first to decline; low progesterone is associated with sleep disruption, anxiety, and irregular cycles
  • FSH (Follicle-Stimulating Hormone) — elevated FSH is one marker of the menopause transition
  • LH (Luteinizing Hormone) — evaluated alongside FSH
  • DHEA-S — an adrenal androgen that serves as a precursor to both estrogen and testosterone; often low in this population
  • Total and Free Testosterone — and this is where the conversation gets critical

Why Testosterone Is the Hormone We Need to Talk About

If there’s one hormone that is consistently undertested, undervalued, and underprescribed for women in perimenopause and menopause, it’s testosterone.

Testosterone is not just a male hormone. Women produce it too — in the ovaries and adrenal glands — and it plays a profound role in female health across the lifespan. In perimenopause, testosterone levels begin to decline alongside estrogen and progesterone. In many women, this decline is significant enough to cause symptoms that dramatically affect quality of life.

What testosterone does in women:

  • Supports libido and sexual desire — testosterone is the primary driver of sex drive in women, not estrogen
  • Maintains muscle mass and strength — critical during a life stage when muscle loss accelerates
  • Supports bone density — works synergistically with estrogen to maintain skeletal integrity
  • Drives energy and vitality — low testosterone is a major contributor to the persistent fatigue that doesn’t respond to sleep
  • Supports cognitive function and mental clarity — emerging research links low testosterone to brain fog and memory difficulties
  • Influences mood and motivation — low testosterone is associated with low motivation, flat affect, and depression

What low testosterone can look like:

  • Loss of libido that doesn’t respond to addressing other factors
  • Persistent fatigue that sleep doesn’t fix
  • Difficulty building or maintaining muscle despite consistent training
  • Loss of strength
  • Flat mood or low motivation
  • Brain fog and difficulty with focus
  • Thinning hair
  • Decreased bone density

Here’s what makes this especially frustrating: testosterone is rarely included in a standard hormone panel for women. Many providers don’t check it at all. And when it is checked, the reference ranges used are often borrowed from male physiology or from general female population studies that don’t account for optimal function in this age group.

A woman whose testosterone is at the very bottom of the “normal” range may be experiencing clinically significant symptoms — but because she’s technically in range, she gets told everything looks fine.

How to Advocate for Testosterone Testing

When you go to your annual exam, ask specifically for:

  • Total Testosterone
  • Free Testosterone (or Sex Hormone Binding Globulin, which affects how much testosterone is biologically available)

Say to your provider: “I’d like to have my testosterone levels checked as part of my hormone panel. I understand it’s not commonly included for women, but given what I know about its role in energy, muscle health, bone density, and libido, I want that baseline.”

If your provider is unfamiliar with testosterone therapy for women or dismisses the relevance of your levels, this is a signal that you may benefit from seeking out a provider who specializes in menopause medicine. Look for someone with MSCP certification through the Menopause Society.

A Note on Hormone Therapy

This post is focused on testing — understanding your hormone picture so you can make informed decisions. Hormone therapy (HT) is a separate and nuanced conversation that deserves its own deep dive, and one that should happen between you and a knowledgeable provider.

What I will say here: the fear of hormone therapy that took root after the 2002 Women’s Health Initiative study has been significantly re-examined by the scientific community. For many women, and particularly for those who begin therapy before age 60 or within 10 years of menopause onset, the benefits of hormone therapy for symptom management, bone protection, and cardiovascular health are well-supported by current evidence.

You deserve to have that conversation with a provider who is current on the evidence. Not one who is still practicing based on 2002.

Your Action Steps

  • Ask for a complete hormone panel at your next appointment — and specifically request testosterone (total and free)
  • Note where you are in your cycle if you’re still cycling — Day 19-21 is optimal for progesterone
  • Track your symptoms alongside your labs — this context is just as important as the numbers
  • Find a menopause-literate provider if your current one isn’t running comprehensive panels or having evidence-based conversations with you

You are not broken. You are not imagining it. You are a woman in a profound hormonal transition who deserves data — and a provider willing to look at it with you.
