What Are the Signs of Low Testosterone in Women?
Last Updated: October 28, 2026
Quick Summary
The most commonly reported signs of low testosterone in women include low libido, persistent fatigue, mood changes, muscle weakness, sleep disturbances, and silent bone loss. None of these proves a hormone problem alone, since each can have other causes, so a written symptom log is useful.
Low libido is one of the most common reasons women raise testosterone with a clinician.
Track symptoms on a 0 to 10 severity scale for two to three weeks before a visit.
Fatigue and mood changes overlap with thyroid problems, iron deficiency, sleep apnea, and depression.
Bone loss is silent and is found only through bone density testing.
Seek care promptly for weight loss, very heavy or absent periods, fainting, chest pain, or self-harm thoughts.

What Testosterone Does in Women
Testosterone is a hormone that women make in small amounts, mainly in the ovaries and adrenal glands.
Many women assume their hormones are only linked to periods and pregnancy. Testosterone is part of a wider hormone system that includes estrogen, progesterone, and cortisol.
Low testosterone in women is less studied than in men. That means symptoms are easy to miss or blame on something else.
Signs and Symptoms of Low Testosterone in Women
Low testosterone usually shows up as a cluster of changes rather than one unmistakable sign. The symptoms below are the signs of low testosterone in women most often reported.
Most women notice two or three of these at once, which is exactly why a written record matters more than memory. A provider can work with a pattern; a vague recollection of "feeling off" is much harder to evaluate.
Low Libido and Changes in Sexual Satisfaction
Low sex drive is one of the most common reasons women raise testosterone with a clinician. You may notice fewer sexual thoughts, less spontaneous interest, or arousal that takes more effort than it used to.
Sex drive is also sensitive to stress, relationship strain, sleep debt, depression, and several medications, including some antidepressants and hormonal birth control.
Fatigue, Mood Changes, and Reduced Motivation
Persistent tiredness that does not improve after a full night of sleep is a frequently reported sign.
Mood can shift in parallel. Irritability, anxiety, low mood, and difficulty concentrating (often called brain fog) are all reported. Many women also notice reduced drive, meaning it is harder to start projects, keep routines, or feel excited about things they usually enjoy.
Fatigue and mood changes are the least specific symptoms on this list.
Muscle Weakness and Loss of Muscle Mass
Testosterone supports muscle maintenance. When levels drop, some women notice that everyday strength feels harder to hold: carrying groceries, climbing stairs, or finishing a workout that used to be routine. Visible muscle loss tends to happen slowly, over months rather than weeks.
A practical way to track this is to pick two or three repeatable measures, such as how many push-ups you can do, how long you can hold a plank, or the weight you use for a standard lift, and record them every two to four weeks. A downward trend across months is more informative than how you feel on any single day.
Bone Loss and Reduced Bone Strength
Bone changes are silent, which is why they rarely show up as a symptom you can feel. Testosterone contributes to bone health in women, and long-term shortfalls are associated with reduced bone density and higher fracture risk. You will not notice this on your own; it is identified through bone density testing when a clinician has reason to order it.
Sleep Disturbances
Trouble falling asleep, waking during the night, and non-restorative sleep are commonly reported alongside low energy and mood changes. Sleep problems can both result from and contribute to hormone-related fatigue, which makes them hard to untangle without a log.
A Practical Symptom-Tracking Guide
A short daily log gives your provider far more to work with than a description of how you feel today. Record these five fields each day for two to three weeks:
Symptom and severity: rate each symptom from 0 (absent) to 10 (severe). Keep the same symptoms on the list so the numbers are comparable.
Onset and duration: note when each symptom first appeared and whether it is constant or comes and goes.
Timing: record sleep hours, menstrual cycle day if you track it, and any obvious triggers such as a stressful week or a missed meal.
Daily-life impact: one line on what the symptom changed, such as leaving work early, skipping a workout, or avoiding intimacy.
Pro Tip Bring the log as a one-page summary, not a notebook. A simple table with dates down the side and symptoms across the top lets a provider spot patterns in under a minute.
When to Seek Care
Contact a clinician promptly if you have symptoms plus any of the following: unexplained weight loss, very heavy or absent periods, fainting, chest pain, or thoughts of harming yourself.
Otherwise, a reasonable step is to book an appointment once you have two to three weeks of logged symptoms. That record turns a vague conversation into a specific one and helps your provider decide which tests, if any, are worth ordering.
The most commonly reported signs are summarised below, along with why each one is hard to attribute to testosterone alone.
Symptom | What it can look like | Caution |
Low libido | Fewer sexual thoughts, less spontaneous interest | Also linked to stress, sleep debt, depression, medications |
Fatigue | Tiredness not improved by a full night's sleep | Overlaps with thyroid problems, iron deficiency, sleep apnea |
Mood changes | Irritability, anxiety, low mood, brain fog | Can also reflect depression or anxiety |
Muscle weakness | Harder everyday strength, slow loss of muscle mass | Changes build over months, not weeks |
Bone loss | Reduced bone density, higher fracture risk | Silent; found only through bone density testing |
Sleep disturbances | Trouble falling asleep, night waking, non-restorative sleep | Can both cause and result from fatigue |
What Causes Low Testosterone in Women
Several factors can lower testosterone in women. Age is a common one. Levels tend to fall gradually after the late twenties, and the drop may speed up around perimenopause and menopause.
Other causes include:
Surgery on the ovaries or adrenal glands, which can reduce hormone production
Certain medications, such as some hormonal birth control methods and corticosteroids
Chronic stress, which can affect the hormones that drive testosterone production
Conditions like polycystic ovary syndrome (PCOS), which can change hormone balance in either direction
Because the causes vary, the same symptom can have very different roots. A provider can help sort out which factors apply to you.
Other Conditions That Can Cause Similar Symptoms
Low testosterone is not the only explanation for these symptoms. Several other conditions can cause the same fatigue, low libido, or mood changes. Some of them are more common than hormone imbalance.
Common examples include:
Thyroid problems, such as an underactive thyroid
Iron deficiency or anemia, which often causes tiredness
Sleep disorders, including sleep apnea
Depression and anxiety, which can reduce libido and motivation
Testing for these conditions can rule them in or out. Doing so before assuming a testosterone problem can save time and point you to the right care.
How a Low Testosterone in Women Test Works
A testosterone test is a blood draw, usually from a vein in the arm (Testosterone Levels Test: MedlinePlus Medical Test). The sample is sent to a lab, and results come back as a number that is compared against a reference range. The process is simple; interpreting the number is where most of the nuance lives.
When a Clinician May Order Testing
Testing is not a routine screening for most women. A clinician is more likely to order it when symptoms are persistent and clustered, when other common causes such as thyroid problems, iron deficiency, and sleep disorders have been considered, and when the results would change what happens next. In practice, the decision usually follows a conversation about symptoms, medical history, medications, and menstrual or menopausal status.
Timing Matters
Testosterone levels rise and fall through the day and shift across the menstrual cycle. Providers commonly ask for a morning draw, and some will time the test to a specific point in your cycle. If you are using hormonal birth control or hormone therapy, tell the clinician before testing, because those medications can affect results and how they should be interpreted.
What Results Can Establish
A result can tell you where your level falls relative to the lab's reference range at the time of the draw. Combined with symptoms and history, it can support a clinical impression and help a provider decide whether further evaluation or a trial of treatment is reasonable.
What Results Cannot Establish
A single number cannot, on its own, explain your symptoms or confirm a diagnosis. Three limits matter most:
Reference ranges vary by lab and method. Two labs can report different ranges for the same sample, so a number is only meaningful next to the range it was measured against.
Levels fluctuate. Day-to-day and cycle-related variation means one low value may not represent your typical level. Repeat testing is sometimes needed before drawing conclusions.
Normal does not mean symptom-free, and low does not mean treatment is needed. Symptoms overlap heavily with thyroid disease, anemia, sleep apnea, depression, perimenopause, and medication side effects. A result in range does not rule those out, and a result below range does not by itself justify hormone therapy.
Watch Out Do not start any hormone product based on an at-home or single lab result without a clinician reviewing your full picture. Dose, formulation, and monitoring all affect safety.
Questions Worth Asking About Your Results
Which lab ran the test, and what reference range applies to my result?
Was the draw timed to my cycle or to a particular time of day, and does that matter for this result?
Do my symptoms and history fit this number, or should we look at other causes first?
If we repeat the test, when should it be done, and what would a different result change?
Bringing these questions to the visit turns a lab report into a decision you understand rather than a number you have to guess about.
Testosterone Treatment for Women: Options, Risks, and Monitoring
If testing and evaluation point to low testosterone, a provider may discuss treatment.
Hormone therapy carries risks. Possible side effects can include acne, hair changes, and voice changes, and long-term safety depends on the type and dose used.
Before starting any treatment, ask your provider about the expected benefits, the risks, how often you will be monitored, and what to do if side effects appear.
Booking Your Discovery Call to Track Your Symptoms
If these symptoms sound familiar, the next step is to talk with a clinician who will look at the whole picture. At PursuitofHealthyness, Lora White, a Nurse Practitioner with a Master's in Nutrition, offers personalized, patient-centered holistic care designed to uncover root causes.
Start by keeping a simple symptom log for two to three weeks. If you'd rather have a clinician evaluate you in person, book a convenient in-home visit for a comprehensive exam and personalized care plan. Note your energy, sleep, mood, sex drive, and muscle strength each day. Bring that log to your first visit so your provider can see patterns over time.

Frequently Asked Questions
What are the signs of low testosterone in women?
The most commonly reported signs include reduced sex drive, lower sexual satisfaction, persistent fatigue, low energy, mood changes such as irritability or anxiety, reduced motivation, and gradual muscle weakness or loss of muscle mass. These symptoms overlap with many other conditions, including thyroid disorders, sleep problems, perimenopause, and depression, so no single symptom confirms low testosterone. Tracking symptoms over several weeks and sharing that log with a clinician is a practical first step.
How is low testosterone diagnosed in women?
Diagnosis usually combines a clinical evaluation of symptoms with blood tests. Because testosterone levels fluctuate and lab reference ranges vary, a single result is interpreted together with symptoms and medical history rather than on its own.
Can low testosterone in women be treated?
Treatment options depend on the cause and the overall clinical picture.
When should a woman talk to a healthcare professional about possible low testosterone?
Consider scheduling an appointment if symptoms such as low libido, persistent fatigue, mood changes, or muscle loss last several weeks and interfere with daily life. Bring a written symptom log, a list of current medications, and any relevant history, including menopause status. A clinician can rule out other causes and decide whether testing is appropriate.
