Could high testosterone in women be PCOS?
High testosterone in women is often linked to PCOS, but other conditions like congenital adrenal hyperplasia, Cushing's syndrome, or certain medications can also cause elevated levels. While PCOS affects 6-12% of women and typically presents with irregular periods and other symptoms, proper testing is essential for accurate diagnosis.
Understanding the Connection Between High Testosterone and PCOS
If you've recently discovered you have high testosterone levels, you might be wondering if polycystic ovary syndrome (PCOS) is the culprit. The short answer is: it's possible, but not guaranteed. While PCOS is indeed the most common cause of elevated testosterone in women of reproductive age, affecting 6-12% of women, several other conditions can also lead to increased androgen levels.
PCOS is a complex hormonal disorder characterized by a combination of symptoms, not just elevated testosterone. Understanding the relationship between high testosterone and PCOS, along with other potential causes, is crucial for getting the right diagnosis and treatment. Let's explore what high testosterone means for women, how it relates to PCOS, and what steps you should take if you're experiencing symptoms.
What Is Considered High Testosterone in Women?
Testosterone is often thought of as a male hormone, but women naturally produce it too, just in smaller amounts. In women, testosterone is produced by the ovaries and adrenal glands, playing important roles in muscle mass, bone density, libido, and overall energy levels.
Normal vs. Elevated Testosterone Levels in Women
| Test Type | Normal Range | Elevated Range | Clinical Significance | |
|---|---|---|---|---|
| Total Testosterone | Total Testosterone | 15-70 ng/dL | >70 ng/dL | Most common test; includes bound and free testosterone |
| Free Testosterone | Free Testosterone | 0.3-3.7 pg/mL | >3.7 pg/mL | Represents biologically active testosterone |
| DHEA-S | DHEA-S | 35-430 μg/dL | >430 μg/dL | Indicates adrenal androgen production |
| Androstenedione | Androstenedione | 0.3-3.3 ng/mL | >3.3 ng/mL | Precursor to testosterone and estrogen |
Reference ranges may vary by laboratory and testing method. Results should be interpreted by a healthcare provider in context with symptoms and other tests.
Normal testosterone levels in women typically range from 15-70 ng/dL (0.5-2.4 nmol/L), though these values can vary slightly between laboratories and testing methods. Levels above this range are considered elevated and may indicate an underlying condition. It's important to note that testosterone levels naturally fluctuate throughout the menstrual cycle and decline with age, particularly after menopause.
When evaluating testosterone levels, healthcare providers often look at both total testosterone and free testosterone. Total testosterone includes both bound and unbound testosterone in the blood, while free testosterone represents the biologically active form. Additionally, other androgens like DHEA-S (dehydroepiandrosterone sulfate) and androstenedione may be measured to get a complete picture of androgen status.
PCOS: The Most Common Cause of High Testosterone in Women
Polycystic ovary syndrome is a hormonal disorder that affects how the ovaries work. Despite its name, not all women with PCOS have cysts on their ovaries. The condition is diagnosed based on a combination of symptoms and test results, following specific diagnostic criteria.
How PCOS Causes High Testosterone
In PCOS, the ovaries produce excess androgens due to a complex interplay of hormonal imbalances. The condition often involves insulin resistance, where cells don't respond properly to insulin. This leads to higher insulin levels, which stimulate the ovaries to produce more testosterone. Additionally, women with PCOS often have elevated levels of luteinizing hormone (LH) compared to follicle-stimulating hormone (FSH), further driving androgen production.
The excess testosterone in PCOS can interfere with normal ovulation, leading to irregular or absent periods. It also contributes to many of the visible symptoms associated with the condition, such as excess hair growth and acne.
Diagnostic Criteria for PCOS
PCOS is diagnosed using the Rotterdam criteria, which requires the presence of at least two of the following three features:
- Irregular or absent ovulation (oligoovulation or anovulation)
- Clinical or biochemical signs of hyperandrogenism (excess androgens)
- Polycystic ovaries on ultrasound (12 or more follicles in each ovary)
It's crucial to note that other conditions that can cause similar symptoms must be ruled out before a PCOS diagnosis is made. This is why comprehensive testing is essential.
Other Causes of High Testosterone in Women
While PCOS is the most common cause, several other conditions can lead to elevated testosterone levels in women. Understanding these alternatives is important for accurate diagnosis and appropriate treatment.
Congenital Adrenal Hyperplasia (CAH)
CAH is a group of inherited disorders affecting the adrenal glands. The most common form, 21-hydroxylase deficiency, can cause the adrenal glands to produce excess androgens. Unlike PCOS, CAH is present from birth and may cause more severe symptoms. Late-onset CAH can sometimes be mistaken for PCOS, making proper testing crucial for differentiation.
Cushing's Syndrome
This condition results from prolonged exposure to high levels of cortisol. While primarily associated with cortisol excess, Cushing's syndrome can also cause elevated androgen levels. Symptoms often include weight gain (particularly in the midsection and upper back), purple stretch marks, easy bruising, and muscle weakness.
Androgen-Secreting Tumors
Though rare, tumors in the ovaries or adrenal glands can produce excess androgens. These tumors typically cause a rapid onset of symptoms and very high testosterone levels (often above 200 ng/dL). If testosterone levels are extremely elevated or symptoms develop suddenly, imaging studies may be necessary to rule out tumors.
Medications and Supplements
Certain medications can increase testosterone levels, including:
- Anabolic steroids
- Some forms of hormonal contraception
- Testosterone replacement therapy (if prescribed for low libido or other conditions)
- DHEA supplements
- Some anti-seizure medications
Symptoms of High Testosterone in Women
Elevated testosterone can cause a variety of symptoms, which may develop gradually or appear suddenly depending on the underlying cause. Common symptoms include:
- Hirsutism (excess hair growth on face, chest, back, or abdomen)
- Acne, particularly along the jawline and chin
- Male-pattern baldness or thinning hair on the scalp
- Irregular or absent menstrual periods
- Difficulty getting pregnant
- Weight gain, especially around the midsection
- Mood changes, including increased irritability or aggression
- Deepening of the voice (in severe cases)
- Enlarged clitoris (in severe cases)
The severity and combination of symptoms can vary greatly between individuals. Some women may have significantly elevated testosterone with minimal symptoms, while others experience noticeable changes with only mildly elevated levels. This variability is partly due to differences in how sensitive individual tissues are to androgens.
Getting Tested: The Path to Proper Diagnosis
If you suspect you have high testosterone or PCOS, comprehensive testing is essential for accurate diagnosis. A thorough evaluation typically includes multiple blood tests, a detailed medical history, and sometimes imaging studies.
Essential Blood Tests
Key hormonal tests for evaluating high testosterone and PCOS include:
- Total and free testosterone
- DHEA-S (to assess adrenal androgen production)
- LH and FSH (to evaluate the LH:FSH ratio)
- Prolactin (to rule out hyperprolactinemia)
- 17-hydroxyprogesterone (to screen for CAH)
- Thyroid function tests (TSH, Free T3, Free T4)
- Fasting glucose and insulin (to assess for insulin resistance)
- Lipid panel (as PCOS increases cardiovascular risk)
For the most accurate results, these tests should ideally be performed in the early follicular phase of your menstrual cycle (days 3-5) if you're still having periods. If your periods are very irregular or absent, testing can be done at any time. Regular monitoring of these biomarkers can help track your progress and adjust treatment as needed.
Additional Diagnostic Tools
Beyond blood tests, your healthcare provider may recommend:
- Pelvic ultrasound to visualize the ovaries
- Glucose tolerance test to assess insulin resistance
- 24-hour urine cortisol or dexamethasone suppression test (if Cushing's syndrome is suspected)
- CT or MRI imaging (if tumor is suspected based on very high testosterone levels)
Treatment Options for High Testosterone
Treatment for high testosterone depends on the underlying cause, your symptoms, and your reproductive goals. For PCOS, which has no cure, treatment focuses on managing symptoms and reducing long-term health risks.
Lifestyle Modifications
For many women with PCOS, lifestyle changes can significantly improve symptoms and hormone levels:
- Weight loss: Even a 5-10% reduction in body weight can improve insulin sensitivity and lower testosterone
- Regular exercise: Both aerobic exercise and strength training can help manage insulin resistance
- Dietary changes: Following a low-glycemic diet can help stabilize blood sugar and insulin levels
- Stress management: Chronic stress can worsen hormonal imbalances
- Adequate sleep: Poor sleep can affect hormone regulation
Medical Treatments
Depending on your specific situation, medical treatments may include:
- Combined oral contraceptives: Can regulate periods and reduce androgen levels
- Anti-androgen medications: Such as spironolactone, which blocks testosterone's effects
- Metformin: Improves insulin sensitivity and may help lower testosterone
- Fertility medications: If trying to conceive, medications like clomiphene or letrozole may be prescribed
- Hair removal treatments: Laser hair removal or electrolysis for managing hirsutism
For conditions other than PCOS causing high testosterone, treatment will target the specific underlying cause. This might include surgery for tumors, medication adjustments, or specific treatments for conditions like CAH or Cushing's syndrome.
Long-Term Health Considerations
High testosterone, particularly when associated with PCOS, can have long-term health implications beyond the immediate symptoms. Women with PCOS have an increased risk of developing:
- Type 2 diabetes
- Cardiovascular disease
- Metabolic syndrome
- Endometrial cancer
- Sleep apnea
- Non-alcoholic fatty liver disease
- Depression and anxiety
This elevated risk makes regular health monitoring crucial. Annual check-ups should include assessments of blood pressure, cholesterol levels, blood sugar, and other metabolic markers. Early detection and management of these risk factors can significantly improve long-term health outcomes.
Taking Control of Your Health
While high testosterone in women is often associated with PCOS, it's important not to jump to conclusions without proper testing and evaluation. The journey to diagnosis may require patience and comprehensive testing, but understanding the root cause of your symptoms is essential for effective treatment.
If you're experiencing symptoms of high testosterone, don't hesitate to seek medical attention. Early diagnosis and treatment can help manage symptoms, improve quality of life, and reduce the risk of long-term complications. Remember that many women successfully manage PCOS and other causes of high testosterone with the right combination of lifestyle changes and medical treatment.
Regular monitoring of your hormone levels and metabolic health markers can help you and your healthcare team make informed decisions about your treatment plan. With proper management, most women with high testosterone can lead healthy, fulfilling lives while minimizing the impact of their condition on their daily activities and long-term health.

What is the difference between PCOS and high testosterone?
High testosterone is a symptom that can occur in PCOS, but PCOS is a complex syndrome requiring at least two of three criteria: irregular periods, high androgens, and polycystic ovaries on ultrasound. You can have high testosterone without PCOS due to other conditions like CAH, Cushing's syndrome, or certain medications.
Can high testosterone levels return to normal?
Yes, testosterone levels can often be normalized with appropriate treatment. For PCOS, lifestyle changes like weight loss and exercise can significantly reduce testosterone. Medical treatments like birth control pills or anti-androgens can also help. The success depends on the underlying cause and individual response to treatment.
What testosterone level indicates PCOS?
There's no specific testosterone level that definitively indicates PCOS. While levels above 70 ng/dL are generally considered elevated in women, PCOS diagnosis requires multiple criteria. Some women with PCOS have only mildly elevated testosterone, while others may have normal levels but still meet other diagnostic criteria.
Should I see an endocrinologist or gynecologist for high testosterone?
Both specialists can help with high testosterone. Gynecologists often manage PCOS and reproductive health issues, while endocrinologists specialize in hormonal disorders. If your primary care doctor suspects a complex hormonal condition or if initial treatments aren't effective, they may refer you to either specialist based on your specific symptoms and needs.
