Testosterone and women over 35
Low Libido, Brain Fog & Fatigue After 35:
The Testosterone Story Every Woman Needs to Hear
You've been told estrogen and progesterone are the hormones that matter for women. But there's a third hormone quietly running your energy, your drive, your body composition, and your sense of self — and most women have never been told they're allowed to optimize it.
Here's something most women leaving their doctor's office never hear: testosterone isn't just a male hormone. Women produce it too — in the ovaries and adrenal glands — and it plays a starring role in how you feel every single day. Energy, motivation, libido, lean muscle, mood, mental clarity, and even bone density are all woven into your testosterone levels. And starting in your mid-30s, those levels begin a slow, steady decline that no one warned you about.
By the time you're in perimenopause or menopause, your testosterone can be half of what it was at its peak. And yet most conventional medicine conversations center only on estrogen. That gap in care is what women's testosterone therapy for Colorado patients at Monday Medical is designed to close.
The Hormone Your Doctor Never Ordered
Think back to how you felt at 25 or 30. You probably didn't think about your energy — you just had it. Workouts felt productive. Your drive was intact. Mornings weren't a negotiation. That vitality wasn't just youth in the abstract. Much of it was driven by optimal testosterone levels working quietly in the background.
After 35, many women start noticing subtle shifts: harder to recover from exercise, less interest in intimacy, a flattening of motivation that's difficult to explain. These changes get dismissed as stress, aging, or "just how things are." But there's often a measurable hormonal explanation — and a personalized solution.
"The research is clear: testosterone plays a vital role in women's physical and emotional health across the lifespan. The question isn't whether women need it — it's whether their levels are where they should be."
What the Science Actually Shows
In 2019, a landmark Global Consensus Position Statement — signed by researchers from 11 major medical societies — analyzed 36 randomized controlled trials on testosterone therapy in women. The findings were unambiguous: testosterone supplementation meaningfully improved sexual function, desire, arousal, and satisfaction. It also showed benefits for energy, mood, and body composition across a range of ages.
This isn't emerging or experimental. It's established science that simply hasn't made it into most primary care conversations. The women who benefit most are those who get a comprehensive hormone panel — not just estrogen and progesterone, but free and total testosterone, SHBG, DHEA, and thyroid — and then work with a provider who knows how to interpret and optimize those numbers.
Signs Your Testosterone May Be Low
Low testosterone in women doesn't announce itself with one dramatic symptom. It tends to show up as a cluster of subtle changes that get attributed to everything else — sleep issues, stress, getting older. Here's what to pay attention to:
- ⚡Persistent fatigue or low energy that doesn't resolve with rest — the kind where coffee stops helping by noon
- 🧠Brain fog, difficulty concentrating, or a sense that your mental sharpness has dulled compared to a few years ago
- 💤Disrupted sleep — trouble falling asleep, staying asleep, or waking unrested despite a full night in bed
- 🔥Decreased libido or reduced interest in intimacy — often one of the earliest and most noticeable signs
- 💪Difficulty building or maintaining lean muscle, even with consistent exercise and adequate protein
- 😔Low motivation, flattened drive, or a subtle mood dip that feels different from typical stress
- 🦴Early bone density concerns — testosterone plays a direct role in skeletal health alongside estrogen

How is women's testosterone therapy delivered? At Monday Medical, testosterone for women is typically administered in low, precisely calibrated doses — far lower than male protocols — via topical cream, subcutaneous pellets, or injection, depending on what fits your lifestyle and goals. The goal is restoration to an optimal range for your age and physiology, not supraphysiologic levels.
The Monday Medical Approach to Women's Hormone Health
At Monday Medical, we don't treat hormones in isolation. Testosterone is evaluated alongside estrogen, progesterone, SHBG, thyroid, cortisol, and other key biomarkers as part of a complete picture. This matters because hormones don't work in silos — they modulate each other, and optimizing one without context can miss the bigger opportunity.
Our providers are skilled in women's testosterone therapy for Colorado patients at all life stages — from women in their 30s noticing the first signs of decline, to those navigating perimenopause or postmenopause who want more than just hot flash management. A free consultation is where we start: listening to your symptoms, understanding your goals, and ordering the right labs.
You don't have to accept a half-version of how you used to feel as the new normal. The science says there's more available to you — and so do we.
