Hirsutism
Evaluate hirsutism by tempo, virilization, menstrual pattern, and objective androgen testing. Most cases reflect PCOS or idiopathic hyperandrogenism, but rapid progression, later onset, or marked biochemical androgen excess requires urgent exclusion of adrenal or ovarian neoplasia.
First decision
Identify hirsutism that needs expedited evaluation
Tempo and virilization determine whether routine outpatient testing is appropriate.
At the first visit, establish age at onset, duration, rate of change, menstrual frequency, acne, female-pattern hair loss, and symptoms or signs of virilization. Assess BMI and blood pressure, and document whether symptoms are distressing enough to warrant treatment. Early-onset, slowly progressive mild androgen-excess features are more compatible with PCOS; late-onset or rapidly progressive virilizing symptoms are more concerning for an androgen-producing tumor.

Actively look for syndrome-specific clues that redirect testing: Cushing syndrome features, severe insulin resistance, genital ambiguity, and findings of congenital adrenal hyperplasia. Genital ambiguity points toward virilizing forms of congenital adrenal hyperplasia; classic CAH may also present with hirsutism when glucocorticoid replacement is inadequate.

If neoplastic androgen excess is suspected on the basis of rapid progression, virilization, or concerning clinical context, make an urgent referral to a center with relevant endocrine and gynecologic expertise.

Testing
Select androgen testing by severity and phenotype
Avoid indiscriminate panels in isolated low-burden hair growth, but do not miss biochemical hyperandrogenism.
Use the clinical examination and modified Ferriman-Gallwey score to determine testing intensity. In isolated hair growth or a low modified Ferriman-Gallwey score, biochemical testing is usually unnecessary. For the common mild presentation without red flags, measure testosterone and SHBG and calculate the free androgen index using the local laboratory reference range; there is no universally accepted normal free androgen index cutoff. BMJBMJFifteen-minute consultation: Approach to the adolescent presenting with hirsutism | ADC Education & Practice Edition
In adolescents with clinical hyperandrogenism, guidelines commonly include total testosterone, free testosterone, or both. A total or free testosterone concentration above adult female normative values supports biochemical hyperandrogenism; interpretation must use the reporting laboratory's adult female reference interval. Wolters KluwerWolters KluwerScreening and Management of the Hyperandrogenic Adolescent
Use a broader androgen panel—17-hydroxyprogesterone, androstenedione, DHEAS, and testosterone—when red flags suggest marked androgen excess, an adrenal process, or another endocrinopathy. This approach is more appropriate than pelvic ultrasonography as the initial universal test for an adolescent presenting with hirsutism.

Interpretation that changes the branch
An elevated 17-hydroxyprogesterone redirects evaluation toward nonclassic congenital adrenal hyperplasia, which can resemble PCOS through menstrual irregularity, hirsutism, and acne. Nonclassic CAH usually has an insidious course beginning around puberty, whereas overt virilization is unusual; this contrasts with the rapid virilization that should heighten concern for an androgen-secreting tumor.

A testosterone elevation does not establish PCOS by itself; use symptom tempo, menstrual history, examination for Cushing syndrome or severe insulin resistance, and 17-hydroxyprogesterone testing to exclude alternate etiologies.

Differential
Separate PCOS, nonclassic CAH, and neoplastic androgen excess
Clinical pattern plus targeted hormones should determine the next referral and treatment pathway.
PCOS is the most common hyperandrogenic disorder associated with hirsutism. A pattern of hirsutism with acne, androgenic alopecia, and menstrual irregularity supports hyperandrogenism, but secondary causes relevant to a PCOS-like presentation include hypothyroidism, hyperprolactinemia, nonclassic congenital adrenal hyperplasia, adrenal or ovarian neoplasms, Cushing syndrome, and acromegaly.

Nonclassic congenital adrenal hyperplasia should be considered particularly when symptoms are insidious from puberty and 17-hydroxyprogesterone is elevated.

Androgen-secreting tumors are uncommon but clinically consequential. Older age, late onset, rapid progression, and virilization are the most useful bedside triggers for urgent specialty assessment. In postmenopausal patients, androgen excess may originate in the ovary or adrenal gland, so the diagnostic strategy should not presume a single source.

Treatment
Treat distressing hair growth while etiologic evaluation proceeds
Management should reflect patient priorities, pregnancy potential, disease severity, and the underlying endocrine diagnosis.
Determine whether treatment is wanted before prescribing medication: in adolescents with hyperandrogenic symptoms, therapy is indicated when acne or hirsutism is distressing to the patient. Pair medical treatment with a hair-removal method selected by the patient, including electrolysis or laser hair removal; eflornithine hydrochloride 13.9% topical cream may help reduce unwanted facial hair.

Oral contraceptive therapy is a longstanding hormonal-suppression option for menstrual irregularity and hirsutism in PCOS, acting in part through suppression of ovarian androgen production. For more severe hirsutism, spironolactone can be added to oral-contraceptive therapy, with closer monitoring for adverse effects than with other options.

Antiandrogens are effective for hirsutism, but selection requires attention to pregnancy risk and contraindications. Spironolactone 100 mg/day has been reported to be more effective than finasteride 5 mg/day for hyperandrogenic hirsutism. Spironolactone is contraindicated in pregnancy, and potassium monitoring is particularly relevant in patients with kidney disease or excessive potassium intake.

Population exceptions
Modify the diagnostic threshold in adolescents and postmenopausal patients
Age and reproductive stage change the pretest probability and interpretation of persistent androgen excess.
In adolescents, physiologic pubertal hyperandrogenism, idiopathic hyperandrogenism, and PCOS can overlap clinically. Obtain total testosterone, free testosterone, or both when biochemical confirmation is needed, screen for nonclassic CAH with 17-hydroxyprogesterone, and use longitudinal evaluation when PCOS remains uncertain. Do not withhold symptomatic treatment solely because diagnostic labeling is still evolving. Wolters KluwerWolters KluwerScreening and Management of the Hyperandrogenic Adolescent
In postmenopausal patients, new androgen excess deserves a lower threshold for source-directed evaluation because ovarian and adrenal etiologies both occur and adrenal androgen-secreting adenomas, although exceptionally rare, have been reported. Document the modified Ferriman-Gallwey score and prioritize the tempo of new or worsening virilization.
