Not just for dryness or for sex. For survival.

I've been thinking about my grandmother a lot lately.

She lived to 95, but the last years of her life were defined by something entirely preventable: chronic UTIs. Constant pain. Antibiotics on rotation that wrecked her gut and caused yeast infections. At some point, she needed a diaper.

She didn't have to be there.

The routine application of vaginal estrogen cream — $20–$30 a month at a compounding pharmacy — may have changed everything. New research shows a 73% reduction in mortality from UTI-related sepsis in postmenopausal women on vaginal estrogen vs. those who aren't (Journal of Urology, 2025).

From a cream. Twice a week.

I believe every woman should start vaginal estrogen by 50 at the latest and take it for life. Not just when something goes wrong. Proactively. New research shows why.

My grandmother's story is why I think about this differently than most doctors do — and it's exactly what I'd want to look at with you before symptoms start: your estradiol, your tissue health, your urinary history. Let's get ahead of this →

You have three options. All work. All are now free of the black box warning that kept women and doctors away from them for 22 years.

The Vaginal Hormone Protocol:

All three restore vaginal tissue, protect against UTIs, and reduce urinary symptoms. DHEA also converts locally to androgens, which makes it particularly useful if sexual function and sensation are a priority.

💡 Forward this to every woman in your life over 40 — and to her doctor.

❌ The old assumption: Vaginal estrogen is for women with severe dryness or pain with sex. Use it short-term. Stop it when symptoms resolve.

✅ The new reality: Vaginal estrogen has negligible systemic absorption, no demonstrated risk of cancer or blood clots, and prevents the tissue decline that leads to UTIs, incontinence, and — at its worst — sepsis and death. The FDA removed its black box warning in November 2025, effective February 2026 (AUA, 2025).

Estrogen receptors line the vaginal walls, urethra, and bladder. When estrogen drops, these tissues thin out, and vaginal pH rises. Lactobacillus — the protective bacteria that block pathogens — disappears. Enterobacteriaceae move in. This is genitourinary syndrome of menopause (GSM), and it affects up to 84% of postmenopausal women (StatPearls, 2024).

Unlike hot flashes, it doesn't resolve. It progresses quietly, for years.

This is how UTIs become deadly in elderly women — not because of the bacteria, but because of what the tissue has become. Persistent UTIs plus a waning immune system leads to pyelonephritis, sepsis, IV antibiotics, hospitalization, and death.

Estradiol cream and inserts work by directly restoring estrogen to vaginal tissue. DHEA works similarly but has added benefits: vaginal cells convert it locally into both estrogens and androgens — a process called intracrinology. Blood levels of either hormone don't meaningfully change (Journal of Steroid Biochemistry, 2008).

The androgen piece matters for sexual function specifically — nerve density, sensation, libido.

Use estradiol for tissue preservation and UTI prevention. DHEA may be especially helpful if sexual function is also part of what you want to address.

One note: DHEA has not been studied in breast cancer survivors — if that's your history, stick with vaginal estradiol.

This is the reframe I want every woman — and our medical system — to make. We treat vaginal hormones like a last resort, something you reach for when it burns, when the UTIs won't stop, when sex is too painful. That's backwards.

Waiting for tissue to atrophy before treating it is like waiting for a fracture before doing bone density work. The goal is to preserve what's there.

You don't need symptoms to pay attention. Notice dryness. Notice changes during sex. Notice UTI frequency, incontinence, or urinary urgency. These are early signals — and early is when intervention does the most.

Estradiol, testosterone, progesterone. Establish a baseline and track how they trend — perimenopause is wildly variable, and some women start fluctuating in their late 30s.

If they express concern about cancer or clot risk, share that the FDA removed the black box warning in February 2026 based on evidence of negligible systemic absorption. If they won't prescribe it, find someone who will.

I'm 44. My hormones look good. I have no symptoms. But I plan to start vaginal estrogen in the next 2–3 years anyway — because tissue preserved early is easier to maintain than tissue that has already atrophied.

The goal: Preserving tissue, protecting your urinary tract, and maintaining your vitality for the next 40 years.

This weekend my 6-year-old daughter got a package in the mail from my mom: an intricately carved, child-sized wooden chest of drawers with an attached vanity mirror that originally belonged to my great-great Aunt Martha — and that my grandmother, my mom, and then I all had in our bedrooms as children. It was made in 1885.

It doesn't really go with our decor, and I'm terrified it's going to get destroyed by her little brother, who is 4 and wields a marker like a weapon. But I love that it's here. It represents a chain unbroken for over 140 years, and reminds me of how much we've changed as a culture — and how much we haven't.

As women, the chest reminds me, self-care can be as simple as organizing our things, brushing our hair, and getting ready for the day in a thoughtful way. These rituals are instilled in us early and stay with us for life. Having the personal space and time to do them is vital to our sense of wellbeing.

But the complexity of what it means to practice self-care as adult women today has exponentially spiraled. Supplements, hormones, DIY weight loss drugs, lab tests, workouts, mental health, skincare — the decisions we're expected to navigate are genuinely overwhelming. As I watched my daughter put on her headband in that little mirror, I felt almost overwhelmed for her. What lies ahead for her? Will it be even more complicated in a world of AI and information overload — or will it somehow get easier?

What I know for myself, my friends, and my patients is that it's become too complex to do alone. Everyone needs a trusted guide — a doctor, or at least a sounding board — to cross-reference questions, triangulate experience, weigh personal values, and make a call. And that's okay.

Longevity, when you think about it, is just a sophisticated form of self-care. And it's not best pursued as a solo mission. It's why I do what I do, and why I'm proud that Parsley exists as a guide for so many people navigating these decisions.

It's also why I write. I hope these newsletters demystify some of the small but important choices you're making every day — as you look in the mirror, or as you watch your children look in theirs. Don't get overwhelmed. Remember that each choice is just one step forward, one piece of the puzzle. You can't go wrong. You're one in a long line of people who were thoughtful about how they took care of themselves — and who did it with love.
