You assumed it was testosterone. For most of the women I see, it is not.

Low libido in midlife has a few consistent drivers, and testosterone, while part of the picture, is the least common primary cause I find in clinic. More often, what I see is cortisol dysregulation suppressing s*x hormone production across the board, progesterone and estrogen instability removing the hormonal foundation that supports desire, and impaired T3 conversion leaving the body in a state of low energy that has nothing left to give.

These are not guesses. They are patterns that show up on a comprehensive hormone panel, one that includes the full s*x hormone cascade, cortisol measured across the day, and a complete thyroid workup including Free T3.

The women who come in convinced they need testosterone replacement often leave with a very different picture of what is actually driving the problem. And addressing the real driver changes things in a way that adding testosterone alone never did.
If this is something you have been quietly wondering about, this is exactly the kind of pattern we investigate.

A single morning cortisol draw is the test most doctors run. It is also the test that tells you the least about what is actually happening.

Cortisol follows a daily rhythm. It should be highest in the morning, rising sharply in the first thirty minutes after waking to mobilize energy for the day. It should decline steadily through the afternoon and reach its lowest point at night, allowing the nervous system to downshift into restorative sleep.

When that rhythm is disrupted, the pattern of disruption is what tells the clinical story. Cortisol that is flat all day. Cortisol that is low in the morning and spikes at night. Cortisol that crashes mid-afternoon and leaves you unable to function. These are three different patterns with three different drivers — and a single morning draw captures none of them.

My customized comprehensive female hormone panel, developed with ZRT Labs over more than twenty years of clinical practice, includes cortisol measured at four points across the day. Morning, midday, afternoon, and evening. The full curve. Because a rhythm problem requires a rhythm assessment.

If you have been told your cortisol is "normal" based on one draw, you have been told the result of an incomplete test.
If your burnout has not resolved despite rest, there is a pattern worth investigating.
