35: Understanding Progestogens in Menopause Hormone Therapy

Ep. 35

Menopause hormone therapy (MHT) can feel like a maze—especially when you start hearing terms like progesterone, progestin, and progestogen used interchangeably. If you’ve ever thought, “Wait… are these all the same thing?” you’re not alone.

In this episode of Reset Recharge, Dr. Komal Patil-Sisodia breaks down one of the most important—and most confusing—parts of menopause care: progestogens. By the end, you’ll know what these hormones do, why they’re essential for many women, and how different options fit different bodies and risk profiles.

Let’s reset the confusion and recharge your hormone literacy.

Progestogens in Menopause Hormone Therapy: What They Are, Why They Matter, and How to Choose the Right One

Why Do We Even Need Progesterone in Menopause?

Estrogen usually gets the spotlight in menopause therapy because it’s the hormone most tied to classic symptoms like:

  • hot flashes and night sweats

  • sleep disruption

  • vaginal dryness

  • mood shifts

  • brain fog

  • joint aches

  • that “my body feels unfamiliar” feeling

For many women, estrogen is what helps them feel like themselves again.

But estrogen also has a powerful effect on one specific organ: the uterus.

If you still have your uterus (meaning you haven’t had a hysterectomy), estrogen on its own can stimulate the uterine lining—called the endometrium—to keep growing. In your cycling years, progesterone balances that growth and triggers the lining to shed. But in menopause, ovulation stops, progesterone drops, and estrogen without a counterbalance can lead to:

  • endometrial thickening

  • endometrial hyperplasia

  • increased risk of endometrial cancer

Even if you’ve had a uterine ablation, this risk still applies because your uterus remains intact.

Bottom line:
If you're taking systemic estrogen and you still have a uterus, you need endometrial protection. That’s what progestogens provide.

A simple way to remember it:

Estrogen helps symptoms.
Progestogens protect the uterus.

Progesterone vs. Progestin vs. Progestogen: The Vocabulary That Matters

These terms get tossed around a lot, but they don’t mean the same thing.

Progesterone

  • The natural hormone your body makes

  • Produced mostly after ovulation

  • Balances estrogen during your cycle

Progestin

  • A synthetic (lab-made) version designed to act like progesterone

  • Protects the uterus

  • Because it’s structurally different, it may have different side effects and risk patterns

  • Common in birth control and also used in MHT

Progestogen

  • The umbrella term

  • Means any compound that activates progesterone receptors

  • Includes both progesterone and progestins

Once you’ve got that language down, the rest becomes much easier to understand.

Types of Progestogens Used in Menopause Hormone Therapy

In menopause care, there are two main groups:

1. Micronized Progesterone

This is progesterone that is chemically identical to what your body naturally makes. “Micronized” just means it’s processed into a form your body absorbs well.

Why many clinicians prefer it:

  • often better tolerated

  • tends to have a more favorable profile for:

    • breast cancer risk

    • cardiovascular health

    • metabolic outcomes

2. Synthetic Progestins

These are highly effective for uterine protection but vary more widely because their chemical structures differ. In the U.S., common options include:

  • medroxyprogesterone acetate (MPA)

  • norethindrone acetate

  • levonorgestrel

  • drospirenone

Outside the U.S., you may also see:

  • dydrogesterone

  • trimegestone

Key point:
Not all progestins are equal. Their differences can affect:

  • breast cancer risk

  • blood clot risk

  • cardiovascular safety

  • metabolic health

  • side effects like mood or breast tenderness

So when someone says “a progestin,” it matters which one.

How Progestogens Are Taken (Routes of Therapy)

Progestogens aren’t one-size-fits-all. They can be delivered through multiple routes:

Oral

  • pills taken daily or part of the month

  • commonly used and easy to adjust

Transdermal

  • patches or gels absorbed through skin

  • may not be as effective for endometrial protection in some cases

Vaginal

  • can be local or systemic depending on formulation and dose

Intrauterine (IUD)

Most often the levonorgestrel IUD, which provides:

  • strong local uterine protection

  • minimal whole-body exposure

  • a great option for women who don’t tolerate oral progestogens or want to reduce systemic risks

Many women also notice lighter bleeding, and some stop periods entirely with this option.

Continuous vs. Sequential: Two Ways to Use Progestogens

Once route and hormone type are chosen, the next decision is how to take it.

Continuous Regimen

  • progestogen taken every day with estrogen

  • often preferred in post-menopause

Pros:

  • steady uterine protection

  • typically no withdrawal bleeding after adjustment

  • simpler routine

Sequential (Cyclic) Regimen

  • progestogen taken 10–14 days per month

  • mimics a natural cycle

  • often used in early perimenopause

Pros:

  • fits better when ovaries still fluctuate

  • can feel emotionally/physically smoother for some women

  • may help manage irregular perimenopausal bleeding

In general:

  • Perimenopause → sequential often fits best

  • Post-menopause → continuous often fits best

But personal preference matters a lot here.

How Do You Choose the Right Progestogen?

There’s no universal “best” progestogen. There’s only the best for you.

Your clinician will consider:

  • Do you have a uterus?

  • Have you had an ablation?

  • Are you perimenopausal or postmenopausal?

  • What symptoms matter most to you? (sleep, mood, bleeding control, breast tenderness, etc.)

  • Personal and family health history

  • Risk factors (cardiovascular, clotting, breast cancer, metabolic health)

  • How you’ve tolerated hormones before

And yes—your best option can change over time as you move through the menopause transition.

Common Myths About Progestogens (Let’s Clear These Up)

Myth #1: “If it says progesterone, it’s all the same.”

Nope. Progestogen is a whole category. Different types have different effects.

Myth #2: “Progestogens are just an annoying add-on.”

Actually, they are critical for safety if you have a uterus. They prevent endometrial cancer in women using estrogen.

Myth #3: “If I feel bad on one, I’ll feel bad on all.”

Not necessarily. Switching type, dose, or route can make a huge difference.

A Simple Example of Why Individualization Matters

Imagine two women, both 52 and using estrogen for hot flashes:

Woman #1

  • has a uterus

  • wants no bleeding

  • has some cardiovascular risk factors
    → A clinician may choose micronized progesterone daily (continuous) for steady protection and safety.

Woman #2

  • early perimenopause

  • still cycling occasionally

  • already frustrated by irregular bleeding
    → She may do better on a sequential regimen, or even an IUD for local protection if systemic options feel rough.

Same goal. Totally different strategy.

Recap: What You Should Remember

  1. If you have a uterus and take systemic estrogen, you need a progestogen.

  2. Progesterone = natural. Progestins = synthetic. Progestogen = umbrella term.

  3. Main options include micronized progesterone and several synthetic progestins.

  4. You can take them orally, vaginally, transdermally, or via IUD.

  5. Continuous regimens = steady protection, minimal bleeding.

  6. Sequential regimens = mimic cycling, often better for early perimenopause.

  7. The right choice is personalized to your body, risks, and goals.

The Takeaway

If you’ve ever been handed a prescription for “progesterone” with no bigger explanation, you deserve more context.

You deserve to know:

  • what it is

  • why it’s there

  • and how it fits your health story

Because the quality of your care often rises with the quality of your questions.
