Dr. Brendan McCarthy

Should every woman take estrogen? Or should no one?

According to Dr. Brendan McCarthy, both extremes miss the point. The best hormone therapy is personalized, evidence-based, and designed around the individual—not headlines or trends.

In this episode, Dr. McCarthy explains why today's growing "estrogen for everyone" movement can be just as concerning as the outdated fear created by the Women's Health Initiative study. Hormone replacement therapy isn't about following the crowd—it's about understanding your body, your risks, and your long-term health goals.

In this video, you'll learn:

Why hormone therapy should never be one-size-fits-all

The difference between individualized care and "pill mill" medicine

What the Women's Health Initiative actually studied—and how it was misinterpreted

Why estrogen helps with some conditions more than others

The questions every woman should ask before starting hormone replacement therapy

How experienced clinicians monitor hormones to keep treatment safe over time

At Protea Medical Center, we believe hormone therapy should be built around you—your symptoms, your lab work, your health history, and your goals.

If you're considering hormone replacement therapy, make sure you're working with a provider who takes the time to explain your options, monitor your progress, and adjust treatment as your body changes.

When someone says, "estrogen causes cancer" or "estrogen causes blood clots," what estrogen are they talking about?

In this episode, Dr. Brendan McCarthy explains one of the biggest misconceptions in hormone replacement therapy (HRT): estrogen isn't a single hormone—it's a family of hormones. Understanding the differences between estradiol, estrone, and estriol can completely change how you view your treatment, your lab work, and the conversations you have with your healthcare provider.

You'll learn why the type of estrogen, how it's delivered (oral, patch, injection, pellet), and how it's monitored all matter. Dr. McCarthy also discusses why informed consent goes beyond signing paperwork—it means truly understanding the treatment you're receiving and why it was chosen for you.

In this episode:

What estradiol, estrone, and estriol actually do

Why estrogen is a family—not a single hormone

How oral estrogen differs from patches, injections, and pellets

Why delivery method changes how your body metabolizes estrogen

The difference between bioidentical, synthetic, and animal-derived estrogens

Why lab timing and monitoring are essential for safe HRT

The importance of true informed consent in hormone therapy

Four questions every patient should ask before starting estrogen

How social media can both educate and create unnecessary fear

The difference between nuanced medical advice and absolute claims

Why the route of estrogen matters when discussing clotting risk

Why does one woman feel incredible on hormone replacement therapy while another gains weight, feels anxious, or sees no improvement at all?

The answer isn't simply the hormone—it's how your body processes it.

In this episode, Dr. Brendan McCarthy explains why the route of hormone delivery (oral, topical, injectable, or pellets) dramatically changes how hormones behave in the body. He also breaks down the role of liver metabolism, sex hormone-binding globulin (SHBG), body fat, inflammation, insulin resistance, and lab timing—and why these factors matter when creating an individualized hormone treatment plan.

You'll learn:

Why the same hormone can produce completely different results in different women

How oral, topical, injectable, and pellet hormones affect your body differently

Why "normal" lab results don't always mean your hormones are optimized

The importance of free testosterone vs. total testosterone

How inflammation, body fat, and liver function influence hormone metabolism

Four questions every woman should ask her hormone provider

Why hormone therapy requires ongoing monitoring—not just a prescription

Hormone replacement therapy is never just about writing a prescription. It's about understanding what your body does with it.

Many women are handed a prescription for hormone replacement therapy (HRT), sign a consent form, and are sent on their way—but is that really informed consent?

In this episode, Dr. Brendan McCarthy explains why true consent is much more than signing paperwork. Understanding what you're taking, why you're taking it, how it's being monitored, and when your treatment should change are essential parts of safe, personalized hormone therapy.

The 5 Questions Every Patient Should Ask:
✔️ What hormone am I taking?
✔️ Why am I taking it?
✔️ How does it get into my body?
✔️ How will we monitor it?
✔️ What would make us change the treatment plan?
