The basics
What is hormone replacement therapy?
Hormone replacement therapy — also called HRT, menopausal hormone therapy (MHT), or hormone therapy (HT) — is a medical treatment that replaces the hormones your body stops producing in sufficient amounts as you approach and enter menopause.
The primary hormones involved are estrogen and progesterone. During perimenopause and menopause, your ovaries gradually produce less of both. This decline is responsible for the wide range of physical and emotional symptoms that many women experience during this transition.
HRT works by supplementing these declining hormone levels — reducing symptoms, supporting long-term health, and helping women feel like themselves again.
Important: HRT is not a one-size-fits-all treatment. The right type, dose, and delivery method depends on your individual health history, symptoms, and goals. Always work with a knowledgeable provider to determine what's right for you.
Estrogen therapy
The primary hormone in most HRT regimens. Addresses most menopausal symptoms. Women who have had a hysterectomy may take estrogen alone.
Combined therapy
Estrogen plus progesterone. Required for women with an intact uterus to protect against endometrial cancer caused by estrogen alone.
Bioidentical hormones
Molecularly identical to the hormones your body naturally produces. Available in both FDA-approved and compounded forms.
Local therapy
Low-dose vaginal options for women whose symptoms are limited to vaginal dryness or urinary issues. Very low systemic absorption.
Who it helps
Symptoms HRT is designed to address
HRT is most commonly prescribed for women experiencing moderate to severe symptoms during perimenopause or menopause that affect daily quality of life. These symptoms are all driven by declining estrogen and progesterone levels.
HRT is also appropriate for women who experience surgical menopause — sudden menopause caused by the removal of both ovaries — which often produces more severe symptoms due to the abrupt drop in hormone levels.
The science
How HRT works in your body
Estrogen receptors exist throughout your entire body — in your brain, heart, bones, skin, bladder, and more. This is why declining estrogen affects so many systems simultaneously, and why restoring it through HRT can have such wide-ranging benefits.
The role of estrogen
Estrogen is the dominant female hormone during your reproductive years. It plays a direct role in regulating body temperature (explaining hot flashes when it drops), maintaining bone density, protecting cardiovascular health, supporting cognitive function, and regulating metabolism and fat distribution.
The role of progesterone
Progesterone balances the effects of estrogen, particularly on the uterine lining. It also supports sleep quality, has a calming effect on the nervous system, and plays a role in mood regulation. In combined HRT, progesterone protects against the endometrial cancer risk associated with estrogen-only therapy.
Sequential vs. continuous combined HRT
Sequential (cyclic) HRT — Estrogen is taken daily, with progesterone added for 10–14 days per month. This typically causes monthly withdrawal bleeding and is often recommended for women in perimenopause who still have occasional periods.
Continuous combined HRT — Both estrogen and progesterone are taken every day without a break. This approach typically does not cause regular bleeding and is usually recommended for women at least 12 months past their last period.
Your options
HRT delivery methods — which is right for you?
One of the most important decisions in HRT is how the hormones are delivered into your body. Each method has different absorption rates, risk profiles, and suitability depending on your lifestyle and health history.
Applied directly to the skin, typically on the arms, thighs, or abdomen. Absorbed through the skin and bypasses the liver entirely.
- Lower blood clot risk than oral estrogen
- Steady hormone levels throughout the day
- Easy dose adjustment
- Good option for women with digestive issues
Worn on the skin and changed once or twice a week. Delivers a consistent dose of estrogen transdermally.
- Convenient — changed just 1–2x per week
- Bypasses liver metabolism
- Lower clot risk vs. oral
- Good for consistent compliance
Taken by mouth daily. The most familiar form of HRT, though it passes through the liver before entering the bloodstream (first-pass effect).
- Familiar and easy to take
- Widely available
- Micronized progesterone has favorable safety profile
- Higher blood clot risk vs. transdermal
Creams, rings, or tablets applied locally for women whose symptoms are limited to vaginal dryness and urinary changes.
- Very low systemic absorption
- Appropriate for women who cannot use systemic HRT
- Highly effective for genitourinary symptoms
- Does not typically require progesterone
Key finding: Research consistently shows that transdermal estrogen (patches and creams) carries a meaningfully lower blood clot risk than oral estrogen — because it bypasses first-pass liver metabolism. This is an important consideration when discussing options with your provider.
Why women choose HRT
The benefits of hormone replacement therapy
When started at the right time and tailored to the individual, HRT offers benefits that go well beyond symptom relief. Here's what the current evidence shows.
Immediate symptom relief
- Significant reduction in hot flashes and night sweats — the most common reason women seek HRT
- Improved sleep quality and duration
- Stabilized mood and reduced anxiety
- Improved mental clarity and cognitive function
- Restored libido and improved sexual function
- Relief from vaginal dryness and discomfort
Long-term health protection
- Bone health: Estrogen is essential for maintaining bone density. HRT reduces the risk of osteoporosis and bone fractures by 50–60%
- Cardiovascular health: When started within 10 years of menopause onset, HRT may reduce cardiovascular disease risk by up to 50%
- Metabolic health: Estrogen supports insulin sensitivity and healthy fat distribution, helping to counteract the metabolic shifts of menopause
- Cognitive protection: Emerging research suggests HRT started early may offer protective benefits for brain health and reduce Alzheimer's risk by up to 35%
- Skin and connective tissue: Estrogen supports collagen production, skin elasticity, and joint comfort
Honest information
Risks, safety considerations, and who should not use HRT
Like any medical treatment, HRT carries risks for some women. Understanding these risks honestly — and in context — is essential for making an informed decision.
HRT is not appropriate for everyone. Women with a personal history of breast cancer, endometrial cancer, stroke, blood clots, or poorly controlled cardiovascular disease should discuss individual risk carefully with a provider before considering HRT. This is not an exhaustive list — a full medical evaluation is always required.
Risk factors to discuss with your provider
- Blood clots: Oral estrogen modestly increases clot risk. Transdermal estrogen (patches, creams) does not appear to carry this same risk
- Breast cancer: Combined estrogen-progesterone therapy is associated with a small increase in breast cancer risk after 5+ years of use. Estrogen-only therapy does not appear to increase risk — and may slightly reduce it
- Stroke: A modest increase in stroke risk has been observed with oral estrogen, particularly in older women. Transdermal delivery reduces this risk
- Endometrial cancer: Estrogen alone can increase uterine cancer risk in women with an intact uterus. Adding progesterone eliminates this risk
- Timing matters: Benefits are greatest and risks are lowest when HRT is started within 10 years of menopause onset or before age 60 — this is called the "timing hypothesis" or "window of opportunity"
The most important thing to understand about HRT risk is that it is highly individual. Your age, health history, family history, the type of hormones used, and how they're delivered all affect your personal risk profile. This is why a thorough consultation with a knowledgeable provider is essential — not a one-size-fits-all decision.
Setting the record straight
Common HRT myths vs. what the evidence actually says
Decades of misinformation have left many women unnecessarily fearful of HRT. Here's what the current science actually shows.
"HRT always causes cancer."
The relationship is nuanced. Estrogen-only HRT does not increase breast cancer risk. Combined HRT is associated with a small increase after 5+ years — but the absolute risk is low, and is affected by the type of progesterone used.
"HRT causes heart attacks."
The 2002 WHI study that created this fear studied an older population with pre-existing cardiovascular risk. Modern evidence shows HRT started early in menopause may actually reduce cardiovascular risk by up to 50%.
"HRT causes weight gain."
HRT does not cause weight gain. In fact, by improving metabolism, reducing cortisol from poor sleep, and supporting insulin sensitivity, HRT may help women manage weight more effectively during menopause.
"You should only use HRT for a short time."
Duration of HRT use is individualized. Many women benefit from longer-term use, especially for bone and cardiovascular protection. The decision should be based on your personal risk profile — not an arbitrary time limit.
"Symptoms are just part of aging — you don't need treatment."
Menopausal symptoms are real, medically valid, and treatable. Declining quality of life from hot flashes, sleep disruption, mood changes, and cognitive symptoms is not something women should simply endure.
Are you a candidate?
Timing, candidacy, and what to expect
The window of opportunity
The timing of when you start HRT relative to your menopause transition significantly affects both the benefits and the risks. Current evidence strongly supports starting HRT within 10 years of menopause onset or before age 60 — a concept known as the "timing hypothesis."
Women who start HRT in this window are most likely to experience cardiovascular protection, cognitive benefits, and bone health support. Starting HRT later — after age 60 or more than 10 years post-menopause — requires a more individualized risk assessment.
Good candidates for HRT typically include women who:
- Are experiencing moderate to severe menopausal symptoms affecting quality of life
- Are under 60 or within 10 years of menopause onset
- Have no personal history of breast cancer, blood clots, or stroke
- Have experienced surgical menopause (removal of ovaries)
- Are concerned about bone density or long-term cardiovascular health
What to expect in your first 3 months
Most women notice improvements in hot flashes and sleep within 2–4 weeks. Mood and cognitive improvements often follow within 4–8 weeks. Common early side effects include mild breast tenderness, light spotting, and occasional nausea — most resolve within the first 2–3 months as your body adjusts.
Breaking news
The 2026 FDA update — what it means for you
In February 2026, the FDA approved label changes to six systemic hormone therapy products, removing black box warnings for cardiovascular disease, breast cancer, and dementia that had been in place since 2002.
These warnings were originally based on the Women's Health Initiative (WHI) study — a study that has since been widely criticized for studying an older, higher-risk population and then applying those findings too broadly to all women considering HRT.
The FDA's decision reflects more than two decades of additional research showing that:
- The original warnings were applied incorrectly to women who were not represented in the original study
- Transdermal delivery significantly reduces many of the risks identified in oral HRT studies
- Timing of initiation dramatically affects both risk and benefit profiles
- For women in the right window, the benefits of HRT clearly outweigh the risks for most
If you were told HRT wasn't safe — that advice may have been based on outdated information. The medical consensus in 2026 is more reassuring than it has been in over two decades. Talk to a provider who is current on the evidence.
