At THRIVE Hormonal Health & Wellness in Lakeway, TX, we hear it all the time: “I just don’t feel like myself anymore.” Often, the conversation eventually circles back to one quiet but powerful influence on how you feel day to day — your sex hormones. Estrogen, progesterone, and testosterone do far more than govern reproduction. They help shape your energy, mood, sleep, focus, bone strength, and sense of vitality.
Understanding how these hormones work — and how they shift over time — can help you have a more informed conversation about your health. Below, our provider Kristine Kjolhede, MSN, FNP-C, walks through what each hormone does and why balance matters for both women and men.
What Sex Hormones Actually Do
Hormones are your body’s chemical messengers. It takes only a tiny amount to create meaningful changes in how your cells — and your whole body — function. That’s why even modest shifts in your sex hormones can ripple out into your mood, metabolism, and overall well-being. Estrogen, progesterone, and testosterone are produced by both women and men, just in different amounts and proportions.
Your hormones are messengers, not just reproductive switches. When they shift, it can show up as low energy, restless sleep, or a mood that feels off — which is exactly why it’s worth understanding them as part of a bigger picture of how you feel.— Kristine Kjolhede, MSN, FNP-C
Estrogen
Estrogen is often thought of as the primary female sex hormone, and it does play a central role in the menstrual cycle, fertility, and pregnancy. But its influence reaches well beyond reproduction. Estrogen helps support bone density, cardiovascular circulation, brain function and focus, and skin health. Men have estrogen too, in smaller amounts, where it contributes to bone and other functions.
As estrogen levels decline — particularly during perimenopause and menopause — some women notice changes in bone strength, temperature regulation, mood, and sleep. Recognizing this connection can help you and your provider build a thoughtful, individualized plan.
Progesterone
Progesterone works closely alongside estrogen — think of them as hormonal teammates. Its main job is to prepare the lining of the uterus for a possible pregnancy and to help maintain that lining when pregnancy occurs. Just as importantly, progesterone helps balance the effects of estrogen.
When progesterone runs low relative to estrogen, some people experience irregular cycles, mood changes, and sleep disruption. Supporting a healthy balance between these two hormones is often part of the broader conversation about how you feel.
Testosterone
Testosterone is frequently labeled a “male” hormone, and it is essential for muscle mass, bone strength, and libido in men. Yet women produce and rely on testosterone too — in smaller amounts made by the ovaries and adrenal glands — where it contributes to sexual desire, mood, and energy.
In men, testosterone tends to decline gradually with age, sometimes producing nonspecific symptoms such as lower energy, reduced drive, or changes in mood. In women, even subtle shifts can affect libido and how they feel overall. Because the right approach is highly individual, decisions about testosterone are best made with a qualified provider who can evaluate your symptoms, labs, and history.
Why Balance Matters — and What May Help
As we age, hormone levels naturally fluctuate, which can contribute to changes in mood, energy, sleep, and libido. The goal isn’t a single magic number — it’s understanding your unique picture. Lifestyle habits can play a meaningful supporting role:
- A nutrient-rich, whole-food diet that supports overall metabolic health
- Regular physical activity, including strength training to support muscle and bone
- Consistent, quality sleep
- Stress management practices that may help your body cope with daily demands
These habits don’t replace medical care, but they may help support how you feel as part of a comprehensive plan. When symptoms persist, an evaluation with a knowledgeable provider can help clarify what’s going on and what options make sense for you.
