New research from the Endocrine Society's ENDO 2026 meeting suggests menopausal hormone therapy offers benefits far beyond hot flash relief, including a 69% lower risk of low bone mineral density, and emerging evidence for brain and mood protection. Here is what the science showed and what it means for your care.
The Headline Finding: 69% Lower Risk of Low Bone Density
In a retrospective cohort study presented at ENDO 2026, researchers followed 387 postmenopausal women who underwent DXA bone scans between 2021 and 2025. One-third used menopausal hormone therapy; two-thirds did not. Women on MHT had about 69% less risk of low bone mineral density in the spine and hip, a finding that held even after researchers accounted for age, time since menopause, vitamin D levels, smoking, and other health conditions.
"In simple terms: menopausal hormone therapy appears to independently protect bones, not just by coincidence. The findings shift the conversation from 'avoid if possible' to 'reconsider in the right patient.'" — Diego Espinoza-Peralta, M.D., M.Sc., principal investigator
Why does this matter? Low bone mineral density (osteopenia and osteoporosis) leads to fractures, disability, and loss of independence. After menopause, declining estrogen accelerates bone loss precisely when many women were told to avoid the one therapy that counters it.
This Confirms What Larger Evidence Already Shows
The ENDO 2026 study was small and retrospective, but it aligns with established data. As Stanford's Dr. Karen Adams noted in MDLinx's coverage of the conference, ACOG already recognizes estrogen therapy (alone or with a progestogen) for preventing bone loss and fracture in women at increased risk. Research shows that after two years of hormone therapy, bone mineral density increases by:
| Site | Increase After 2 Years |
|---|---|
| Lumbar spine | 6.8% |
| Forearm | 4.5% |
| Femoral neck | 4.1% |
Hormone therapy is not the only tool. Weight-bearing exercise, a balanced diet, adequate vitamin D, and not smoking all meaningfully protect bone. But for women already considering MHT for symptoms, bone protection may be a significant added benefit.
Beyond Bones: Brain and Mood
Cognitive Health
Evidence continues to build around the "timing hypothesis", meaning that when you start hormone therapy matters. Women who begin MHT near menopause show better long-term cognitive outcomes, and research from Northwestern found hormone therapy does not increase cardiovascular risk in younger postmenopausal women, further supporting early-window use in appropriate candidates.
Mood and Options for Women Who Cannot Take Hormones
Separate ENDO 2026 research found that fezolinetant, a non-hormonal prescription treatment, improves not only hot flashes and night sweats but also depression and anxiety in menopausal women.
"It's thankfully not an all-or-nothing conversation of either you get estrogen, or you get nothing at all." — Dr. Alyssa Dominguez, USC endocrinologist
For women with a history of breast cancer, blood clots, or other contraindications, effective options exist.
What This Means for You
Three takeaways from this year's research:
- Hormone therapy is being re-evaluated as a long-term health strategy for bones and potentially brain and heart, not just symptom relief.
- Timing matters: the early postmenopausal window appears to be when benefits are strongest.
- If hormones are not right for you, non-hormonal treatments like fezolinetant now address both hot flashes and mood.
What the research does not say: that MHT is right for everyone. The bone study was small and retrospective, and every woman's risk profile (age, time since menopause, personal and family history) changes the equation. That is not a reason for inaction; it is a reason for individualized care.
Don't Navigate This Alone
Here is the frustrating reality: 70% of women feel dismissed when discussing menopause symptoms with their doctor, and most physicians receive little to no menopause training. Research like this only helps you if your provider knows it, stays current with it, and applies it to your body and history.
That is exactly what Amsara Health practitioners do. Our specialists dedicate their practice to midlife women's health and build personalized plans around your symptoms, history, and goals, including an evidence-based conversation about whether hormone therapy belongs in yours.

Frequently Asked Questions
Does hormone therapy protect against osteoporosis?
Research presented at ENDO 2026 found menopausal hormone therapy was associated with a 69% lower risk of low bone mineral density in the spine and hip. ACOG recognizes estrogen therapy for preventing bone loss and fracture in women at increased risk.
How much does HRT increase bone density?
Studies show that after two years of menopausal hormone therapy, bone mineral density increases by about 6.8% at the lumbar spine, 4.5% at the forearm, and 4.1% at the femoral neck.
Does hormone therapy help with brain fog and memory?
Evidence suggests women who start hormone therapy near menopause (the "timing hypothesis" window) have better long-term cognitive outcomes. Individual results vary, so discuss timing with a menopause specialist.
What if I cannot take hormones? Is there an alternative for hot flashes?
Yes. Fezolinetant, a non-hormonal prescription medication, treats hot flashes and night sweats, and ENDO 2026 research found it also improves depression and anxiety in menopausal women.
When is the best time to start menopausal hormone therapy?
Benefits appear strongest when therapy begins in the early postmenopausal window, generally within 10 years of menopause onset and before age 60. A specialist can assess your individual timing and risk profile.
