Our read is that menopausal Hormone Replacement Therapy (HRT) is well supported for improving healthspan and mitigating various age-related risks.
Our read is that HRT, when initiated around the time of menopause, can offer significant benefits for cardiovascular health, bone density, brain health, and overall healthspan.
Experts suggest that the widespread avoidance of HRT, largely due to misunderstandings of past studies, has contributed to an epidemic of osteopenia and osteoporosis.
While there are considerations regarding timing and specific protocols, the consensus leans towards judicious use of HRT to improve health outcomes.
HRT should ideally be initiated around menopause, within the first ten years of cessation of periods, and before atherosclerosis is established. It should be started before a woman reaches a menopausal state with flat-lined estradiol and progesterone and very high FSH/LH. Dennis Erdman MD suggests HRT should be administered for both men and women. Options include vaginal rings for local and systemic treatment, IUDs for progesterone, and topical testosterone. Labs should be checked, not just symptoms. Women with pre-existing cardiovascular disease are generally not recommended to start hormone therapy.
Starting testosterone replacement therapy can increase the risk of sleep apnea and cause sleep disturbances (Andrew Huberman, 1x). Long-term combination hormone replacement therapy increases breast cancer risk, and bone loss accelerates after stopping HRT (Peter Attia, 1x). The headline that HRT increases breast cancer risk by 27% is based on an inappropriate context, as the absolute risk increase was only 0.1% (Andrew Huberman, 1x). Menopausal hormone therapy is generally not recommended if a woman is more than 10 years past menopause or over age 65 (Peter Attia, 1x). Not taking hormone therapy in postmenopausal women carries risks including genitourinary changes, increased UTIs, pelvic pain, osteoporosis, hip fractures, dementia, Alzheimer's, and cardiovascular disease (Peter Attia, 1x). The pellet industry for hormone replacement therapy has issues regarding women's health due to lack of FDA-approved pellets and insufficient safety/efficacy studies (Peter Attia, 1x). HRT is not ideal for bone health in women in their 40s and 50s due to their low risk of osteoporotic hip fracture (Peter Attia, 1x). Hormone replacement therapy is a serious medical intervention that is often administered incorrectly (Peter Attia, 2x). The idea that labs should never be checked and only symptoms matter in hormone therapy is incorrect (Peter Attia, 1x). The belief that HRT increases the risk of dying from breast cancer is a misconception (Peter Attia, Rhonda Patrick, 2x). Estrogen therapy lowers Lipoprotein(a) levels but is not recommended solely for this purpose due to potential increased cardiovascular risk (Peter Attia, 1x). The Women's Health Initiative study results were misunderstood and misinterpreted, leading to a decline in HRT prescription (Peter Attia, 6x). For women with established cardiovascular disease, HRT may increase risk due to inflammatory markers and a pro-thrombotic effect (Peter Attia, 1x).
The evidence for hormone replacement therapy's application in perimenopausal women is not robust (Peter Attia, 1x). Menopause hormone therapy's impact on metabolic flexibility requires further research and should be combined with lifestyle interventions (Peter Attia, 1x). More robust evidence for perimenopausal application and metabolic flexibility impact would change the verdict.
Benefits hold across the populations where it's been tested.
The effect size is large enough to matter clinically, not just statistically.
Mechanistic and trial evidence converge on a real, replicable effect.
Widespread avoidance of HRT following the Women's Health Initiative study has contributed to an epidemic of osteopenia and osteoporosis in postmenopausal women.
When initiating HRT in perimenopausal women, lower doses can be used compared to full menopause.
