You’re tired in a way that sleep doesn’t fix. Or, you have a mental fog that makes you feel like you’re wading through molasses. And your mood swings from “fine” to “frazzled” without warning. So you do the responsible thing. You see your doctor, talk about stress, get your thyroid checked, and perhaps have a chat about estrogen or progesterone. You’re told this is stress, aging, or simply “part of being a woman.” What almost never comes up is testosterone. We’ve been conditioned to think of it as the “male hormone.” But that’s a myth that’s done a massive disservice to women for decades. The truth is, testosterone is a _human_ hormone. Women produce it naturally, and they need it to feel strong and like themselves. You need to know how testosterone works inside your body to get your symptoms to _make_ sense. ## Key Takeaways 1. Persistent fatigue, brain fog, low libido, and stubborn weight gain are common signs of a testosterone imbalance in women. 2. The standard reference range for testosterone is too broad and misses functional deficiencies. 3. Castle Rock Hormone Health uses personalized hormone optimization plans to help women [optimize their testosterone levels](https://crhormonehealth.com/women/hormone-optimization/) to feel _right._ ## The Real Benefits of Testosterone for Women Testosterone is involved in how women think, move, recover, and feel every day. When levels are right for _your_ body, here’s how they’ll affect you: ### 1\. Energy Levels Testosterone affects your mitochondrial function, the process your cells use to produce energy and help you move. Research shows that [when testosterone is low](https://pmc.ncbi.nlm.nih.gov/articles/PMC8721233/), your mitochondria become less efficient at using glucose and fatty acids. In women, this means the kind of exhaustion that doesn’t respond to sleep, caffeine, or stress reduction. ### 2\. Mental Focus Testosterone affects mental functions [related to attention](https://pubmed.ncbi.nlm.nih.gov/34175996/), motivation, and how fast you understand things. A [2024 study on women](https://pmc.ncbi.nlm.nih.gov/articles/PMC11151480/) aged 55 to 90 found that those with lower free testosterone levels were more likely to experience brain impairment as they aged. Interestingly, these effects appear to be stronger in women than in men. This could mean that women may be sensitive to testosterone loss when it comes to brain health. ### 3\. Mood Stability While testosterone mostly affects sex function, it can also influence your emotional regulation and stress tolerance. [Low levels of testosterone in women](https://www.mdpi.com/2673-4184/3/3/33) are increasingly linked to irritability, anxiety, low mood, depression, and reduced emotional well-being. ### 4\. Body Composition Testosterone helps you maintain lean muscle mass and fat metabolism. This has a direct impact on weight regulation, strength, and how your body responds to exercise. When testosterone is _optimal_ for the body, women find it easier to build and maintain muscle, recover from workouts, and manage weight, even without changing their routine. When it falls, you might [begin storing more fat](https://pubmed.ncbi.nlm.nih.gov/36585396/) and lose muscle. ### 5\. Bone Health Bone density declines with age, especially after menopause. Testosterone has an [anabolic effect on your bones](https://pubmed.ncbi.nlm.nih.gov/36180560/), meaning it can build and strengthen them. Studies show that using [testosterone for menopausal women](https://pmc.ncbi.nlm.nih.gov/articles/PMC12808602/) slows down bone loss and reduces the risk of osteoporosis and fracture risk. As Dr. Lee puts it right: “Not only does testosterone treat the symptoms of menopause, it reverses bone loss.” This is one of the most overlooked benefits of [hormone therapy for your health goals](https://crhormonehealth.com/blog/hormone-therapy-for-health-goals/). ### 6\. Sexual Function Testosterone therapy for women can [lead to significant improvements in sexual function](https://pubmed.ncbi.nlm.nih.gov/31353194/), including desire, arousal, and the ability to orgasm. A review confirmed that [testosterone helps improve discomfort](https://pubmed.ncbi.nlm.nih.gov/39211827/), dryness, and desire in postmenopausal women. ## Signs of Testosterone Hormone Imbalance in Women Testosterone imbalance in women doesn’t always show up as one obvious symptom; it often appears as a pattern your body keeps repeating. In high-functioning women, these signs are easy to overlook or dismiss, even when testosterone is functionally low or unavailable, and standard labs appear normal. **Here are signs of a testosterone hormone imbalance in women:** * **Persistent, bone-deep fatigue that sleep or “healthy” habits don’t fix.** This happens when testosterone levels are functionally low. * **Weight gain that won’t budge, especially around the midsection.** When testosterone levels in women drop or become unavailable, the body can’t maintain muscle. So fat storage becomes easier, especially around the abdomen. * **Low libido or complete loss of interest over time.** Testosterone [influences your brain to modulate sexual motivation](https://pmc.ncbi.nlm.nih.gov/articles/PMC10522204/) and responsiveness. When it’s functionally low, you can become numb to sexual cues. * **Brain fog, difficulty focusing, forgetting words, and losing mental sharpness.** Low testosterone can [reduce brain chemical activity](https://pmc.ncbi.nlm.nih.gov/articles/PMC11151480/). It can impact your mental sharpness, memory, or focus. * **Difficulty building or maintaining muscle.** Testosterone helps [build muscle mass in women](https://pmc.ncbi.nlm.nih.gov/articles/PMC6391653/) (just as it does in men). When it falls, your body struggles to develop or maintain lean mass. * **Being told your labs are “normal,” while you feel terrible.** You can have a lab value that falls within a reference range and still be functionally depleted. This is especially true if the testosterone your body produces is unusable. At Castle Rock Hormone Health, one of our main advocacies is to educate patients about the effects of hormones in your body and how optimization can help. ## Understanding Testosterone Levels in Women One of the most confusing parts of hormone health for women is this: you can feel very unwell and still be told your testosterone levels are “normal.” Here’s why standard tests don’t tell you what’s wrong: ### 1\. They Have a Very Wide Reference Range The reference range for [testosterone levels in women](https://crhormonehealth.com/blog/testosterone-myths/) is wide, and it includes people who feel great and people who feel terrible. So when a lab value falls somewhere in that range, you might be told that testosterone isn’t the issue, even if symptoms clearly suggest otherwise. But one thing you need to understand is that “normal” on a range and “normal” for your body are two different values: * **Normal**. This is a broad statistical average taken from a massive population. It tells you what’s common, not what’s right for you. You can be at the very bottom of this huge range, feel awful, and still be handed a “normal” stamp of approval. * **Optimal**. This is the specific testosterone level for your body where you feel energetic, clear-headed, and strong. So just because your report says your [testosterone levels are normal](https://crhormonehealth.com/blog/normal-testosterone-levels/) doesn’t mean they’re _optimal_ for your body. ### 2\. They Test Total Testosterone What most women aren’t told is that the number on their lab report is total testosterone, not how much testosterone their body can actually use. In your bloodstream, testosterone doesn’t float around freely. A large portion of it is bound to proteins, especially sex hormone–binding globulin (SHBG). When testosterone is bound, it’s essentially locked away. It can’t enter cells, influence energy production, support muscle, or affect mood and cognition. This is why symptoms and labs so often don’t match. What actually matters is free testosterone, the small fraction that is unbound and biologically active. This is the testosterone your body can access and use. Unfortunately, many standard hormone panels don’t calculate it, and many providers never look at SHBG at all. ![testosterone myths]() ## 8 Testosterone Myths Related to Women You Need to STOP Believing Explore testosterone myths that stop women from getting proper care. Discover the science behind safe hormone optimization today! [ Read More ](https://crhormonehealth.com/blog/testosterone-myths/) ## The Hidden SHBG Problem in Women Sex hormone-binding globulin (SHBG) is a protein made by your liver. Its job is to bind to sex hormones, including testosterone. It regulates how much of those hormones are available to your tissues. When SHBG levels rise, your free testosterone drops, even if your body is producing enough overall. This means while you have enough testosterone in your body, it’s locked away. So you feel tired all the time, can’t retain muscle, and have brain fog that lasts for days. **Your SHBG levels can increase if you:** * **Take oral contraceptives**. When you take synthetic hormones, your body responds by [ramping up production of SHBG](https://pmc.ncbi.nlm.nih.gov/articles/PMC7663738/) to regulate them. * **Experience inflammation**. Women are [four times more likely than men](https://pmc.ncbi.nlm.nih.gov/articles/PMC7980266/) to develop autoimmune conditions, which can create chronic inflammation. This inflammation signals your liver to increase SHBG production in your body. * **Have thyroid dysfunction**. When your thyroid is underactive, it causes your liver to produce more SHBG. * **Eating disorders**. When your body is in a prolonged state of starvation or extreme dieting, the liver increases SHBG. This is thought to be an attempt to reduce active sex hormones and save energy for survival. This further lowers your available testosterone. “Even if you might have a normal total testosterone, you’re testosterone-depleted because all that SHBG is just holding on to it, and you can’t ever get it into your cells,” Dr. Lee explains. This is why our team at [Castle Rock Hormone Health](https://crhormonehealth.com/) goes beyond the standard test. “We do a calculation on the testosterone so we can actually really calculate what your free testosterone is,” Dr. Kelli explains. “We really focus on that here rather than just the total testosterone number.” Without accounting for SHBG and free testosterone, your test results can come out looking fine while your body feels like it’s not your own anymore. ## Why Your Doctor Hasn’t Mentioned Testosterone Therapy for Women If testosterone can make such a big difference in the health of women, why did you never know about it? The answer can be traced back to a single moment in medical history that changed women’s hormone care for decades. In the early 2000s, the [Women’s Health Initiative](https://pmc.ncbi.nlm.nih.gov/articles/PMC6780820/) (WHI) trial became the largest experiment ever conducted on hormone replacement therapy (HRT). It was intended to be a landmark study, and it was, just not in the way women needed. The study linked hormone therapy to serious health risks, including coronary artery disease and breast cancer. This caused a large-scale stopping of HRT because of the fear that it might do more harm than good. But the science behind that conclusion didn’t hold up. The average age of the women in the study was 63, over a decade past menopause. In addition, the hormonal dosages used in the study were inappropriate, and the statistical claims were misrepresented. “That whole research has just been debunked,” Dr. Kelli says. “There were a lot of errors within that research study.” Yet the fear stuck, and it has affected how generations of physicians were trained to think about hormone therapy. The [FDA later removed the black box warning](https://www.fda.gov/news-events/press-announcements/hhs-advances-womens-health-removes-misleading-fda-warnings-hormone-replacement-therapy) on hormone therapy in 2025\. But many clinical providers continue to operate on information they learned decades ago. “The last couple of decades with all the bad research and fear mongering, along with all the cancer scares, that’s kind of being debunked,” Ben puts it. “But most doctors haven’t caught up.” The reason this knowledge hasn’t reached women is that: * Medical training focuses on diagnosing disease and treating problems once they appear, not on optimizing health _before_ symptoms become severe. * Conversations about energy, mood, libido, and long-term wellness often fall outside what insurance covers. Even interested doctors rarely have the time or resources to talk about them. That’s why testosterone therapy for women is still rarely mentioned. The system never prioritized the kind of individualized, preventive care women need. ## Why You Don’t Have to “Just Accept” Menopause Twenty years ago, hormone optimization therapy was feared. Misinterpreted studies and outdated warnings left generations of women believing that menopause symptoms were a part of life. But today, the science is very different. “My wife has never experienced menopause at 48,” Dr. Lee says, “because I’ve been tracking her hormones.” He monitors her hormone levels over time, including testosterone, estrogen, and progesterone, and adjusts them to what’s _optimal_ for her body. This ensures that her energy, mood, libido, and wellness rema
