She was 44. Good marriage. Kids she adored. A life that looked, by every outside measure, like exactly what she'd wanted. Zero interest in her husband. Not anger, not resentment. Just nothing. A flatness where something used to be.
She'd brought it up once at a doctor's visit. The conversation lasted maybe two minutes. She left with a suggestion for couples therapy.
She didn't have a relationship problem. She had a testosterone level of 7 ng/dL and estrogen that had been quietly dropping for two years.
The hormones were the missing piece for her.
They are not always.
Women's sexual desire is genuinely complicated, more complicated than most clinical encounters allow for. It's shaped by estrogen, testosterone, and DHEA, but also by sleep, stress, body image, medications, emotional safety, and the fact that female desire tends to be responsive rather than spontaneous. It doesn't show up on its own the way it often does for men. It needs context.
That's not a dysfunction.
That's how it works.
The problem is when this gets flattened.
The problem is when this gets flattened. Low libido gets filed under hormones, or under relationship stress, or under "you're in your 40s, this is normal" — and the actual picture never gets looked at.
A real workup starts with: when did this change, and what else changed around the same time? It checks hormones, but it also asks about medications, sleep, and pain. Most women with this complaint have never had that conversation — let alone the bloodwork.
This problem isn't female specfic. Male testosterone peaks in late 20s and declines 1-2% per year after 30.
By 50, a significant number of men have levels that are technically "in range" but functionally low. The range is wide enough that a man can feel completely different at either end of it.
Male sexual function is largely vascular. Hypertension, metabolic syndrome, insulin resistance; these aren't separate from sexual health, they're upstream of it. If something has changed and nobody has looked at the full picture, the workup isn't done.
And if you're a man reading this because your wife or partner has pulled away — this is for you too. What she's experiencing likely has a hormonal explanation that nobody has looked at. Getting her the right workup is a real starting point. It won't fix everything on its own, but it's hard to address anything else when her body is working against her.
One number worth knowing:
Women got their first FDA-approved medication for low sexual desire in 2015.
Men have had options since 1998.
That's not a biological gap. It's a research gap and it took significant advocacy to close even partially.
My patient started low-dose testosterone. Three months later she sent a portal message: "I don't know what changed but I feel like myself again."
That was it. Clean answer, for her. A lot of women are working with something more complicated, and the answer takes longer to find. But you can't find it without looking.
My colleague Dr. Arti Thangudu did a great episode covering the psychological dimensions of this — body image, the erotica data, why the cognitive side of women's desire matters as much as the hormonal side. Worth an hour of your time: Endocrine Matters Podcast

One thing worth flagging for anyone dealing with dryness specifically: Ube Lube is what I recommend — pH-balanced, free of glycerin and parabens, designed to work with vaginal tissue rather than against it.
