If you have started reading about hormone therapy, you may have discovered that "HRT" is not one thing. It is a family of options: estrogen worn as a patch, rubbed on as a gel, sprayed on the skin, or swallowed as a pill, usually paired with a form of progesterone, plus local vaginal estrogen and, in some cases, testosterone. Each form works, and each has its own profile of convenience, benefits, and risks. This guide walks through the main types in plain language so you can have a more informed conversation, because the right type of HRT is genuinely individual and is chosen with your doctor.
Key Takeaway
HRT is usually built from estrogen plus, if you have a uterus, a progestogen to protect the womb lining. Estrogen comes as a skin patch, gel, or spray (delivered through the skin, and associated with a lower blood-clot risk than tablets), an oral pill, or a low-dose vaginal product for local symptoms only. Progesterone is most often micronized progesterone by mouth or a levonorgestrel intrauterine system. Testosterone may be added for persistent low sexual desire. No single type is best for everyone. Both The Menopause Society and NICE stress that the right form is matched to your health history and preferences with your doctor. This article is education, not medical advice.
The Two Building Blocks of HRT
Almost all HRT is assembled from two ingredients. The first is estrogen, which is the hormone that eases the classic symptoms of the transition such as hot flashes, night sweats, and some of the changes to mood and sleep. The second is a progestogen, a term that covers natural progesterone and its synthetic cousins. If you still have your uterus, a progestogen is added because estrogen on its own can thicken the womb lining over time. Progesterone keeps that lining in check.
Two simple facts flow from this. If you have had a hysterectomy, you usually take estrogen alone. If you have not, you take estrogen plus a progestogen. Everything else, patch versus pill, sequential versus continuous, is about how those two ingredients are delivered and timed for you.
Estrogen: Patch, Gel, Spray, or Pill
Estrogen is the part with the most delivery choices, and the choice is not trivial, because how estrogen enters the body changes its risk profile.
Through the skin (transdermal)
Patches, gels, and sprays are grouped together as transdermal estrogen. The hormone is absorbed through the skin straight into the bloodstream, so it does not pass through the liver first. This matters: both The Menopause Society and NICE note that transdermal estrogen is associated with a lower risk of blood clots (venous thromboembolism) than estrogen taken as a tablet, and it does not appear to carry the same clot-risk signal. For this reason it is often the preferred route for women who have clot risk factors, migraine with aura, or a higher body mass index.
- Patch: a small adhesive patch changed once or twice a week. Steady, low-maintenance, and easy to stop simply by removing it.
- Gel: a measured amount rubbed into the skin daily, allowing flexible dose adjustment. It needs a few minutes to dry and to avoid transferring to others.
- Spray: a metered spray applied to the skin daily, another flexible transdermal option.
By mouth (oral)
Estrogen tablets are the oldest and most familiar form. They are simple to take and effective for symptoms. The trade-off is that oral estrogen passes through the liver first, which is linked to a somewhat higher risk of blood clots compared with the transdermal route. For many healthy women in early menopause the absolute risk remains low, but it is a key reason a doctor may steer toward a patch or gel if you have particular risk factors.
Comparing the Delivery Methods
This table summarizes how the common forms differ. It is a general guide to help you ask questions, not a ranking, and it does not replace personalized advice.
| Form | How it is used | Notable points | Often considered for |
|---|---|---|---|
| Estrogen patch | Adhesive patch, changed once or twice weekly | Transdermal, so lower clot risk than tablets; steady levels; easy to stop | Convenience, clot risk factors, migraine, higher BMI |
| Estrogen gel | Rubbed into the skin daily | Transdermal; flexible, adjustable dosing; needs drying time | Those who prefer daily control of dose |
| Estrogen spray | Metered spray to the skin daily | Transdermal; flexible dosing; quick to apply | An alternative to gel for skin delivery |
| Estrogen pill | Tablet taken by mouth daily | Passes through the liver first; associated with higher clot risk than transdermal | Simplicity when clot risk is low |
| Micronized progesterone | Capsule by mouth, usually at night | Body-identical; can aid sleep; protects the womb lining | Most women needing endometrial protection |
| Levonorgestrel IUS | Small device placed in the uterus | Local progestogen; also provides contraception; lasts several years | Those wanting contraception plus womb protection |
| Vaginal estrogen | Cream, pessary, tablet, or ring, used locally | Very low dose; minimal absorption into the body; treats local symptoms only | Vaginal dryness, discomfort, urinary symptoms |
Progesterone and Why It Matters
If you have a uterus, the progestogen is not an optional extra. It is what keeps estrogen from over-stimulating the womb lining. There are a few ways to take it.
- Micronized progesterone is a body-identical form, usually taken as a capsule at night. Many women find it also helps with sleep. Some evidence suggests micronized progesterone may have a more favorable breast and cardiovascular profile than certain older synthetic progestogens, though it is prescribed based on your overall picture.
- Synthetic progestogens (progestins) such as those found in some combined patches and tablets are also effective at protecting the lining and may suit some women.
- The levonorgestrel intrauterine system (IUS) releases a small amount of progestogen directly into the uterus. It protects the womb lining, and it doubles as contraception, which can matter in perimenopause when pregnancy is still possible.
Combined HRT: Sequential and Continuous
When estrogen and a progestogen are used together, the timing of the progestogen defines the regimen, and the right one depends largely on where you are in the transition.
| Regimen | How it works | Usually for |
|---|---|---|
| Estrogen-only | Estrogen with no progestogen | Women who have had a hysterectomy |
| Sequential (cyclical) combined | Estrogen every day, progestogen for part of each month, usually producing a monthly bleed | Perimenopause, when periods have not fully stopped |
| Continuous combined | Estrogen and progestogen every day, aiming for no monthly bleed | Postmenopause, typically once periods have stopped for about a year |
This is why two women can both be "on HRT" and yet be taking quite different regimens. A woman still having irregular periods may be on a sequential plan, while a postmenopausal woman is more likely on a continuous combined one.
Vaginal Estrogen for Local Symptoms
Vaginal estrogen sits a little apart from the rest. It comes as a cream, pessary, tablet, or a soft ring, and it is used locally to treat the genitourinary symptoms of menopause, such as vaginal dryness, discomfort during sex, and some urinary symptoms. Because the dose is very low and absorption into the rest of the body is minimal, it is generally considered safe for local use, it can be used alongside systemic HRT, and it usually does not require an added progestogen. It does not treat hot flashes or other whole-body symptoms, so it is often used on its own for local issues or added to systemic HRT.
A practical way to prepare
Before your appointment, jot down three things: your main symptoms and how much they bother you, your relevant health history (blood clots, migraine, breast conditions in the family), and your practical preferences (daily gel versus a twice-weekly patch, for example). Bringing this makes it far easier for your doctor to match a form of HRT to you rather than starting from a blank page.
Body-Identical vs Compounded "Bioidentical" HRT
You will likely come across the words "bioidentical" and "body-identical," and they are not the same thing.
Body-identical HRT uses hormones structurally identical to your own, in regulated, licensed, quality-tested products. In practice this usually means transdermal estradiol (a patch, gel, or spray) with micronized progesterone. These are mainstream, evidence-based options.
Compounded bioidentical hormones are custom-mixed preparations, often marketed with saliva or blood hormone testing and claims of being more "natural" or precisely tailored. The Menopause Society and NICE advise against these compounded products, because they are not regulated, standardized, or tested for purity, dose accuracy, and safety in the same way licensed HRT is. If a "natural, custom" hormone treatment is being sold to you outside standard regulated care, that is a reasonable moment to pause and ask questions.
Where Testosterone Fits In
Testosterone is often thought of as a male hormone, but women produce it too, and levels decline with age. In menopause care, the main evidence-based use is for persistent low sexual desire (reduced libido that is causing distress) when standard HRT alone has not resolved it. The Global Consensus Position Statement, endorsed by The Menopause Society and other bodies, supports testosterone for this specific indication, typically as a carefully dosed cream or gel with monitoring. It is worth knowing that for women this is frequently an off-label use, formulations licensed specifically for women are limited in many places, and it is prescribed and followed up by a clinician. It is not a general energy or wellbeing booster.
How the Right Type Is Chosen
There is no universally "best" type of HRT, and any article claiming one is oversimplifying. The choice weaves together several threads that only you and your doctor can see in full.
- Your symptoms: whole-body symptoms point to systemic estrogen; purely local symptoms may be handled by vaginal estrogen alone.
- Your health history: clot risk, migraine, higher BMI, and other factors may favor the transdermal route over tablets.
- Whether you have a uterus: this determines whether a progestogen is needed.
- Where you are in the transition: perimenopause versus postmenopause shapes sequential versus continuous regimens, and whether contraception is still relevant.
- Your preferences: a patch you barely think about, a gel you control daily, a capsule that helps you sleep. What you will actually stick with matters.
Guidance from The Menopause Society and NICE is consistent on the principle: HRT is individualized, ideally started at the lowest effective dose that manages your symptoms, and reviewed over time. The benefits and risks differ by age, time since menopause, personal history, and the type and route you choose, which is exactly why this is a shared decision, not a one-size answer.
