Virilization
What is Virilization?
Virilization is a condition where a woman develops masculine physical traits due to excess male hormones, particularly androgens. These changes happen when the body produces too much testosterone or similar hormones. The condition affects appearance, voice, and body composition.
Most cases occur when the adrenal glands or ovaries produce abnormally high levels of androgens. The adrenal glands sit on top of your kidneys and make various hormones including DHEA-S, which converts to testosterone. When something disrupts normal hormone production, virilization symptoms can develop gradually or appear suddenly.
Early detection through blood testing helps identify the root cause before symptoms become severe. Understanding your hormone levels enables you and your doctor to create a targeted treatment plan. Testing for DHEA-S and other androgens provides critical information about what is happening in your body.
Symptoms
- Deepening of the voice that does not reverse
- Male-pattern hair loss or thinning at the temples
- Excessive facial or body hair growth, especially on the face, chest, or back
- Enlargement of the clitoris
- Decreased breast size
- Increased muscle mass and body strength
- Absent or irregular menstrual periods
- Acne that is severe or difficult to treat
- More masculine body shape with fat redistribution
- Increased sex drive
Some women may notice only mild symptoms at first, like irregular periods or increased body hair. Early signs can be subtle and easy to dismiss. Rapid development of multiple symptoms requires immediate medical attention, especially voice changes or clitoral enlargement.

Causes and risk factors
The most common causes include polycystic ovary syndrome, adrenal tumors, ovarian tumors, and congenital adrenal hyperplasia. PCOS affects up to 10% of women and causes mild to moderate virilization through ovarian androgen production. Adrenal or ovarian tumors are less common but produce very high androgen levels that cause rapid symptom onset. Congenital adrenal hyperplasia is a genetic condition affecting enzyme production in the adrenal glands.
Risk factors include family history of hormonal disorders, obesity, insulin resistance, and certain medications. Anabolic steroid use causes virilization in women who take these substances for athletic performance or bodybuilding. Age also plays a role, as some conditions like adrenal tumors can occur at any age while PCOS typically affects women of reproductive age. Sudden onset of severe symptoms suggests a tumor and requires urgent evaluation.
How it's diagnosed
Diagnosis starts with blood tests measuring androgen levels including testosterone, DHEA-S, and androstenedione. DHEA-S testing is particularly important because markedly elevated levels suggest an adrenal source rather than ovarian. Your doctor will also check other hormones like cortisol, 17-hydroxyprogesterone, and luteinizing hormone to pinpoint the cause.
Rite Aid offers DHEA-S testing as part of our flagship preventive health panel. Testing through Quest Diagnostics locations provides accurate baseline measurements to track your hormone levels. If blood tests show very high DHEA-S levels, your doctor will order imaging studies like CT or MRI scans to look for adrenal or ovarian tumors. Early testing helps catch problems before symptoms become irreversible.
Treatment options
- Treating the underlying cause, such as tumor removal through surgery when present
- Medications to block androgen production or action, including spironolactone or finasteride
- Birth control pills to regulate hormones and reduce androgen levels
- Glucocorticoids for congenital adrenal hyperplasia to replace missing enzymes
- Weight loss and insulin-sensitizing medications like metformin for PCOS-related virilization
- Cosmetic treatments for hair removal or voice therapy for permanent changes
- Regular monitoring through blood tests to ensure hormone levels return to normal ranges
- Stopping any androgen-containing medications or supplements immediately

Frequently asked questions
Adrenal or ovarian tumors are the most serious causes and require urgent attention. These tumors produce very high levels of androgens that cause rapid symptom development. Markedly elevated DHEA-S levels suggest an adrenal tumor. Imaging studies and prompt treatment are essential when tumors are suspected.
Some symptoms can improve with treatment while others may be permanent. Hair growth patterns, clitoral enlargement, and voice deepening often do not fully reverse even after hormone levels normalize. Early treatment prevents additional changes from occurring. Treating the underlying cause stops progression and may improve symptoms like menstrual irregularity and acne.
Symptom timeline depends on the underlying cause. PCOS-related virilization develops slowly over months to years with gradual changes. Tumor-related virilization can develop rapidly over weeks to months with dramatic changes. Sudden onset of multiple symptoms requires immediate medical evaluation to rule out tumors.
Normal DHEA-S ranges vary by age and lab, but levels above 700 mcg/dL in adult women raise concern. Markedly elevated levels above 800 to 1000 mcg/dL strongly suggest an adrenal tumor, especially with virilization symptoms. Your doctor will interpret results based on your age, symptoms, and other hormone levels.
Hirsutism refers only to excess hair growth in male-pattern areas. Virilization includes hirsutism plus other masculine changes like voice deepening, clitoral enlargement, and muscle development. Hirsutism alone is common and often related to PCOS. Virilization represents more severe androgen excess requiring thorough investigation.
Lifestyle changes help when PCOS or insulin resistance contributes to virilization. Weight loss of 5 to 10% can improve hormone levels and reduce symptoms in overweight women with PCOS. Regular exercise and a balanced diet support insulin sensitivity. However, tumors and congenital adrenal hyperplasia require medical treatment beyond lifestyle modification alone.
Testing frequency depends on your diagnosis and treatment plan. Initial evaluation may require testing every 4 to 8 weeks to monitor treatment response. Once hormone levels stabilize, testing every 3 to 6 months helps ensure they remain in normal ranges. Your doctor will determine the right schedule based on your specific situation.
Anabolic steroids and testosterone supplements are the most common medications causing virilization in women. Some bodybuilding supplements contain hidden androgens that can trigger symptoms. Danazol, used for endometriosis, can also cause virilization with long-term use. Always tell your doctor about all medications and supplements you take.
Yes, virilization often affects fertility because the same hormone imbalances disrupt normal ovulation. Absent or irregular periods mean eggs are not being released regularly. Treating the underlying cause can restore normal menstrual cycles and improve fertility. Many women with PCOS-related virilization can conceive with appropriate treatment.
See a doctor promptly if you notice voice deepening, clitoral enlargement, male-pattern hair loss, or rapid development of multiple symptoms. These signs suggest significant androgen excess requiring evaluation. Even milder symptoms like persistent irregular periods with increasing facial hair warrant testing. Early diagnosis prevents irreversible changes and identifies serious causes like tumors.
