Signs of low testosterone in women: what your symptoms may be telling you
Your labs came back normal. You still feel like someone turned the dial down on your energy, your strength, and your desire. Both can be true.
Fatigue that sleep doesn't fix. Strength slipping at the gym. Less interest in sex, and less response when you do. A flatness where your drive used to be.
These symptoms are real. But they don't always come from the first cause that gets named.
Women make testosterone too, in the ovaries and the adrenal glands. Levels run far lower than in men, yet testosterone still plays a part in sexual function, muscle, bone, and several other tissues. Levels fall gradually with age. They can drop faster after surgical removal of the ovaries, with certain medications including oral estrogen and some birth control pills, or with changes in ovarian or adrenal function.
And here is the part that frustrates women most. Symptoms alone can't confirm that testosterone is the cause. Neither can a single lab value.
Five symptom patterns, and what else causes each one
Each of these can lead a clinician to include testosterone in a broader hormone evaluation. Each one also has other explanations that deserve to be ruled in or out first.
Sexual health changes
What women describe: Lower desire. Slower arousal or less responsiveness. Fewer sexual thoughts. Less satisfying experiences. Vaginal dryness or discomfort.
What else causes it: Declining estrogen, genitourinary syndrome of menopause, antidepressants and other medications, chronic health conditions, stress, relationship strain, and broken sleep. More on women's sexual wellness at Navara.
Energy and stamina
What women describe: Persistent fatigue. Reduced endurance. Less motivation to exercise. Slower recovery. Trouble keeping up with an activity level that used to be easy.
What else causes it: Thyroid dysfunction, anemia, low iron stores, vitamin deficiencies, sleep disorders, insulin resistance, depression, chronic stress, and under-eating. Thyroid is the one most often "checked" without being fully tested, which is why we built a dedicated thyroid evaluation.
Muscle, strength, and body composition
What women describe: Less muscle tone. Difficulty holding on to lean muscle. Lost strength. A shift in body shape, often more weight through the middle.
What else causes it: Aging, menopause, falling estrogen, low protein intake, inactivity, thyroid dysfunction, and insulin resistance. When metabolism is the main driver, medical weight management may be the better starting point.
Mood, motivation, and focus
What women describe: Low motivation. A dimmer sense of wellbeing. Irritability. Symptoms that look like depression. Brain fog and trouble concentrating.
What else causes it: Perimenopause, menopause, poor sleep, thyroid dysfunction, medication side effects, life stressors, depression, and anxiety.
Hair, skin, bone, and joints
What women describe: Thinning hair. Dry or thinning skin. Joint aches. Lower bone density. Feeling less physically resilient overall.
What else causes it: Estrogen status, thyroid function, iron and nutrition, genetics, inflammation, medications, and other medical conditions. Scalp thinning can even come from too much androgen activity rather than too little. See how we work up women's hair loss.
Is there a testosterone level that diagnoses deficiency in women?
No. There is no single testosterone number that reliably defines a deficiency syndrome in women.
The Global Consensus Position Statement on Testosterone Therapy for Women found that no testosterone cutoff separates women with sexual dysfunction from women without it. The Endocrine Society advises against diagnosing androgen deficiency from a testosterone result alone.
The test method matters too. Many standard lab methods were designed around male testosterone levels and lose accuracy at the low concentrations women carry. So a result gets read alongside how it was measured, your symptoms, your history, your medications, where you are in your cycle or in menopause, and the rest of your labs. Our PCOS and Androgen Evaluation panel measures testosterone alongside the markers that give it context.
A low number is not a diagnosis. A normal number is not an answer. A low result does not automatically mean you need treatment. A result inside the reference range does not explain why you feel the way you do.
What a complete hormone evaluation looks at
Symptoms blamed on low testosterone overlap with a long list of other hormonal and medical problems. Depending on your history, a thorough evaluation covers:
- Menstrual and menopause history
- Estradiol and progesterone status
- Thyroid function
- Iron and ferritin
- Complete blood count
- Metabolic health
- Sleep quality
- Current medications
- Nutrition and protein intake
- Stress and mental health
- Sexual pain or vaginal symptoms
- Prior hysterectomy or ovary removal
- Personal and family health history
That breadth is the point. It keeps one symptom or one lab value from standing in for the entire answer. For a fuller breakdown, read what labs to ask for.
Testosterone and perimenopause
Perimenopause has no fixed start date. It can begin in your late thirties or your mid forties, and it rarely announces itself. If you are wondering whether it has started, start with Is it perimenopause or something else?
During the transition, estrogen and progesterone can swing hard from one month to the next. Testosterone declines more gradually. So when fatigue, poor sleep, mood changes, brain fog, lower desire, and a changing body all show up together, several hormones and several systems are usually involved at once.
That is exactly why "your labs are normal" is not an acceptable place to stop when you are still struggling. But the answer isn't to blame every symptom on testosterone either. The answer is a careful, head-to-toe evaluation that finds what is actually driving the change.
Does testosterone therapy help women?
For one condition, yes. Current international consensus identifies hypoactive sexual desire disorder (HSDD) in appropriately evaluated postmenopausal women as the primary evidence-supported reason for systemic testosterone therapy.
The International Society for the Study of Women's Sexual Health clinical guideline calls for a complete biopsychosocial evaluation before testosterone is considered for HSDD. Treatment aims to bring levels back into the normal female range, never above it. And no testosterone product is currently FDA-approved specifically for women in the United States, which belongs in the conversation too.
The evidence does not support promising that testosterone will fix fatigue, weight gain, depression, cognitive changes, bone loss, or general wellbeing.
That does not mean those symptoms get brushed aside. It means they get a real workup for other causes, and any treatment discussion lays out the likely benefits, the limits, the unknowns, and the risks in plain language.
What we cover before treatment starts
If testosterone therapy is on the table, you should leave that visit knowing:
- Which specific symptoms we are treating, and what else could be causing them
- Which benefits are expected and which are uncertain
- Baseline labs before you start, then follow-up visits and ongoing monitoring
- Fertility, pregnancy, and contraception when they apply
- How limited the long-term safety data in women still is
And you should know the changes to watch for:
- Most common: acne, oily skin, and more facial or body hair.
- Less common: changes in scalp hair and clitoral enlargement.
- Can be permanent: voice deepening. Report any hoarseness or change in your voice right away.
When to schedule a hormone evaluation
Book an evaluation when symptoms persist, interfere with your life, or feel like a clear break from your usual self. That includes:
- Ongoing fatigue with no clear explanation
- Lower sexual desire or responsiveness that bothers you
- Lost strength, muscle tone, or exercise recovery
- New trouble with mood or concentration
- Menopause symptoms that still aren't controlled
- Symptoms that continue after you were told your labs are "normal"
- Concerns after a hysterectomy, ovary removal, or early menopause

Frequently asked questions
Can a blood test diagnose low testosterone in women?
Not on its own. No testosterone cutoff reliably identifies deficiency in women, and many standard assays lose accuracy at female levels. A result is one piece of the evaluation, read together with your symptoms, history, medications, and other labs.
Will testosterone fix my fatigue or weight gain?
The evidence doesn't support that promise. Testosterone therapy in women is best supported for low sexual desire (HSDD) after menopause. Fatigue and weight changes deserve their own workup, because thyroid, iron, sleep, metabolic health, and estrogen status are frequent drivers.
My labs are normal but I still feel off. What now?
Normal labs rule some things out. They don't explain your symptoms. A complete evaluation looks at your full history, life stage, and a broader set of markers to find what is actually contributing to the change you feel.
What are the side effects of testosterone in women?
The most common are acne, oily skin, and increased facial or body hair. Less common changes include scalp hair changes, clitoral enlargement, and voice deepening, which can be permanent. Careful baseline testing and follow-up monitoring are part of any treatment plan.
