What Is Hormone Replacement Therapy? A Guide for Men and Women

By Zahida, MSN, AGNP-C, CCRN — Board-Certified Nurse Practitioner | Z&Z Wellness Alexandria, VA

Hormone replacement therapy (HRT) is a medical treatment that restores hormones your body no longer produces in adequate amounts. 

It is one of the most effective, evidence-based treatments for hormonal imbalance in both men and women—yet it remains one of the most misunderstood.

If you’ve been experiencing unexplained fatigue, stubborn weight gain, brain fog, low libido, or mood changes, a hormonal imbalance could be the root cause. These aren’t just “normal aging.” They’re signals your body needs support.

At Z&Z Wellness in Alexandria, VA, we use bioidentical hormones—molecularly identical to what your body naturally produces—to create personalized treatment plans based on your lab work, symptoms, and health goals. Here’s what you need to know.

Signs You May Need Hormone Replacement Therapy

Hormonal decline can begin as early as your 30s and accelerates through your 40s and 50s. Many people don’t realize their symptoms are hormone-related until they get tested. Common signs of hormonal imbalance include:

•       Persistent fatigue that doesn’t improve with rest

•       Weight gain, especially around the midsection, despite diet and exercise

•       Brain fog, poor memory, and difficulty concentrating

•       Low libido or sexual dysfunction

•       Mood swings, irritability, anxiety, or depression

•       Hot flashes, night sweats, and sleep disruption

If several of these sound familiar, a simple blood test can reveal whether your hormones are out of balance.

HRT for Women: Beyond Menopause

While menopause is the most common reason women seek HRT, hormonal shifts can also occur during perimenopause, after pregnancy, during prolonged stress, or with conditions like PCOS and thyroid dysfunction.

By restoring estrogen, progesterone, and—when appropriate—testosterone to balanced levels, HRT can eliminate hot flashes and night sweats, restore energy and mental clarity, support healthy metabolism, stabilize mood, revitalize libido, and strengthen bones. Research published in The Lancet and endorsed by the North American Menopause Society (NAMS) supports the safety and effectiveness of bioidentical HRT when initiated within 10 years of menopause onset.

TRT for Men: What Is Testosterone Replacement Therapy?

Testosterone replacement therapy (TRT) is hormone therapy specifically designed to restore testosterone levels in men with clinically low testosterone. Men lose approximately 1–2% of their testosterone per year starting around age 30. By their 40s and 50s, many men experience noticeable symptoms—sometimes called andropause.

TRT can improve energy and motivation, support lean muscle growth and fat loss, sharpen mental focus, restore libido and sexual function, and improve mood and sleep quality. Studies in the New England Journal of Medicine have demonstrated meaningful improvements in energy, sexual function, and mood in men receiving testosterone therapy.

Bioidentical vs. Synthetic Hormones: What’s the Difference?

Bioidentical hormones are derived from plant sources and are molecularly identical to the hormones your body naturally produces. 

--This is an important distinction from the older synthetic hormones—like Premarin and Provera—used in the 2002 Women’s Health Initiative (WHI) study that raised safety concerns.

--Modern bioidentical HRT, especially when delivered through topical methods like creams and pastes rather than oral pills, carries a significantly different risk profile. At Z&Z Wellness, we prescribe only bioidentical hormones with delivery methods chosen to maximize safety and effectiveness.

Frequently Asked Questions About HRT

Is hormone replacement therapy safe?

When properly prescribed and monitored, bioidentical HRT has a strong safety profile. Much of the fear around HRT comes from the 2002 WHI study, which used synthetic hormones and oral estrogen—very different from the bioidentical hormones and topical delivery methods used in modern practice. Regular lab monitoring ensures your levels stay within a safe, optimal range.

How soon will I see results from HRT?

Many patients notice improved sleep, energy, and mood within the first 2–4 weeks. Changes in body composition, libido, and mental clarity typically develop over 2–3 months as hormone levels fully optimize.

What is the difference between HRT and TRT?

HRT is the broader term for any hormone replacement therapy. TRT (testosterone replacement therapy) is a specific type of HRT focused on restoring testosterone in men with clinically low levels. Women may also receive testosterone as part of a comprehensive HRT plan.

Do you treat both men and women?

Yes. Z&Z Wellness in Alexandria, VA provides hormone replacement therapy for women experiencing perimenopause, menopause, and hormonal imbalance, as well as testosterone replacement therapy for men with low testosterone.
