Today’s clip comes from one of our most replayed conversations: The Great Estrogen Debate.

In this episode, Dr. Felice Gersh, Dr. Daved Rosensweet, Dr. Lindsey Berkson, Dr. Julie Taguchi, and Karen Martel discuss one of the most important and misunderstood topics in women’s hormone health: estrogen replacement therapy.

If you have ever wondered about the difference between estrone, estradiol, and estriol, or whether women should use estradiol-only HRT versus a combination of estradiol and estriol, this conversation will help you better understand the debate.

The experts explore how different types of estrogen work in the body, why hormone ratios matter, and how estrogen can influence breast health, bone health, brain health, cardiovascular health, inflammation, immune function, and overall hormone balance.

They also discuss why starting hormone support during perimenopause may help some women better maintain natural hormone rhythms, and why individualized treatment plans, proper dosing, and specialized hormone therapy training are so important.

Why the Estrogen Debate Matters

Estrogen is often talked about like it is one single hormone, but that is not accurate. Women produce different types of estrogen, including estrone, estradiol, and estriol, and each plays a different role in the body.

This is why the conversation around HRT can feel so confusing. Some practitioners prefer estradiol-only hormone therapy, while others believe combining estradiol with estriol may better mimic the body’s natural hormone patterns.

In this episode, we explore both sides of the discussion so women can better understand the questions to ask when considering hormone replacement therapy.

FAQ

What is the difference between estrone, estradiol, and estriol?

Estrone, estradiol, and estriol are three different types of estrogen. Estradiol is the strongest and most active form during reproductive years, estrone becomes more dominant after menopause, and estriol is produced in higher amounts during pregnancy. Each type of estrogen plays a different role in women’s hormone health.

Is estriol used in hormone replacement therapy?

Some hormone practitioners use estriol alongside estradiol in hormone replacement therapy, while others prefer estradiol-only therapy. The best approach depends on the woman’s symptoms, health history, hormone levels, goals, and provider’s clinical training.

Why does estrogen matter after menopause?

Estrogen affects much more than hot flashes. It also plays a role in bone health, brain health, cardiovascular health, vaginal health, skin, mood, sleep, inflammation, and overall quality of life.

Is hormone replacement therapy one-size-fits-all?

No. HRT should be individualized based on a woman’s symptoms, lab work, medical history, risk factors, goals, and response to treatment. Proper dosing, delivery method, and follow-up are essential.

Why is the estrogen debate important?

The estrogen debate matters because women are often given oversimplified information about HRT. Understanding the different types of estrogen, how they work, and how they may be used in therapy can help women make more informed decisions with a qualified provider.
