Low Testosterone in Women

When most people hear the words "low testosterone," they picture a problem that only affects men. The truth is that women need healthy testosterone too. This hormone quietly supports your energy, mood, sex drive, muscle, and bones, so when levels drop, the effects can touch almost every part of daily life.

Can women really have low testosterone?

Yes. Testosterone is one of the main hormones the female body makes, even though women carry far less of it than men. The ovaries and adrenal glands produce it, and it works alongside estrogen and progesterone to keep your body running smoothly. According to the Cleveland Clinic, testosterone helps regulate sex drive, bone strength, and red blood cell production in both sexes, which is why a shortage can affect women so broadly (Cleveland Clinic).

If you have noticed unexplained fatigue, low desire, or a body that no longer responds the way it used to, an underlying hormone imbalance may be part of the picture. The good news is that these shifts are measurable and treatable.

What causes low testosterone in women?

Testosterone is built from cholesterol, so anything that disrupts that pathway can lower your levels. Common causes include the use of cholesterol-lowering medication such as statins, low progesterone (progesterone is a precursor for testosterone), and oral contraceptives that suppress the production of sex hormones like estrogen, progesterone, and testosterone. Natural aging is another major driver.

Levels of androgens decline steadily across a woman's reproductive years, and by the time many women reach midlife their testosterone is a fraction of what it was in their twenties. Research published through the National Library of Medicine notes that testosterone supports bone density, muscle mass, cognitive function, mood, sexual function, and energy in women (National Library of Medicine). When that hormone falls, all of those systems can feel the strain.

Symptoms of low testosterone in women

Low testosterone rarely announces itself with one dramatic symptom. Instead, it tends to show up as a cluster of changes that build slowly over time. Here are the signs women report most often.

Loss of libido

One of the most recognizable symptoms of low testosterone is a drop in sex drive and sexual function. This has been widely studied, and it is the symptom most directly tied to declining testosterone levels in women. The international consensus on female hormone health recognizes hypoactive sexual desire as the best-supported reason to consider testosterone therapy in women (International Menopause Society consensus). If reduced desire is your main concern, a clinician can help you explore whether female low libido has a hormonal root.

Weight gain and difficulty losing weight

Testosterone plays a significant role in body weight, glucose balance, and how the body handles fats. Normalizing testosterone may improve insulin sensitivity and have favorable effects on belly fat and lipid profiles. A drop in testosterone can also lead to a loss of muscle mass. Because muscle burns more calories than fat and keeps the metabolism active, less muscle tissue can lead to additional weight gain. Increasing testosterone while balancing estrogen may help reverse this loss of muscle.

Fatigue

There is strong evidence that testosterone follows a daily, or circadian, rhythm in both sexes. Sleep raises testosterone and waking lowers it, and this rhythm is linked to both energy and sexual function. When baseline levels are too low, that natural lift may not be enough to carry you through the day, leaving you drained even after a full night of rest.

Mood swings, depression, and anxiety

In women, but not in men, lower free testosterone is associated with more depressive symptoms. In other words, as a woman's free testosterone drops, low mood and anxiety can rise. This connection helps explain why some women notice emotional changes alongside the physical ones.

Difficulty concentrating and brain fog

The balance between estrogen and testosterone, along with their byproducts, appears to matter for thinking and memory in women. In one study, testosterone improved verbal learning and memory in healthy postmenopausal women. Both men and women with Alzheimer's disease have also been shown to have lower brain levels of estrogen and testosterone than people without the disease.

Beyond these symptoms, low testosterone has been linked to higher cardiovascular risk and a greater chance of coronary problems in older women. Restoring healthy levels can also support bone density and reduce the risk of osteoporosis.

How is low testosterone in women treated?

Treatment starts with simple blood testing to confirm where your levels actually sit, since symptoms alone can overlap with thyroid problems, stress, and other conditions. If testing confirms a deficiency, your clinician can build a plan around your symptoms and goals. The U.S. National Library of Medicine explains that hormones act as the body's chemical messengers, so even small imbalances can ripple outward into mood, metabolism, and reproductive health (MedlinePlus).

At ageRejuvenation, our team of licensed MDs, DOs, and ARNPs uses bioidentical hormones that are structurally identical to the hormones your body makes on its own. Because they match your natural chemistry, these hormones tend to cause fewer side effects. For many women, a carefully monitored hormone replacement therapy program for women restores energy, mood, and desire over a series of follow-up visits. Professional guidance matters here, because expert bodies such as the Endocrine Society stress that testosterone use in women should be carefully dosed and monitored (Endocrine Society).

Hormone care is one piece of a larger picture. Exploring the full range of services in our women's health clinic helps you address related concerns, from thyroid support to menopause symptoms, under one coordinated plan.

Frequently Asked Questions

What is considered a low testosterone level in a woman?

Normal ranges are much lower for women than for men and vary by lab and life stage. Because there is no single universal cutoff, a clinician reads your numbers alongside your symptoms rather than relying on one figure. Blood testing during a consultation is the only reliable way to confirm a true deficiency.

What depletes a woman's testosterone?

Aging is the biggest factor, since androgen levels fall gradually from a woman's twenties onward. Other contributors include statin use, low progesterone, oral contraceptives that suppress sex hormone production, and removal of the ovaries. Chronic stress and poor sleep can also push levels down.

What does low testosterone feel like in women?

Many women describe a quiet, creeping loss of vitality: lower sex drive, persistent fatigue, harder weight management, low mood, and trouble concentrating. Because these symptoms overlap with other conditions, testing is important to identify whether testosterone is truly the cause.

Can low testosterone in women be treated safely?

Yes, when it is supervised by qualified clinicians. Treatment begins with lab testing, then careful dosing and regular monitoring to keep levels in a healthy female range. Bioidentical hormones that match your natural chemistry are a common, well-tolerated option.

How long does it take to feel better after starting treatment?

Timelines vary by person, but many women begin noticing improvements in energy, mood, and desire over several weeks to a few months of consistent, monitored care. Your provider will track your symptoms and labs and adjust your plan as needed.
