What is the appropriate management for a 19-year-old female with hyperandrogenism (elevated testosterone levels)?

Management of Hyperandrogenism in a 19-Year-Old Female

The appropriate management for a 19-year-old female with hyperandrogenism (elevated testosterone levels) should begin with a thorough diagnostic evaluation to determine the underlying cause, followed by targeted treatment based on the etiology.

Diagnostic Approach

Initial Laboratory Evaluation

• Measure total testosterone (preferably in the early morning) and confirm with a second measurement on a separate occasion 1
• Measure serum luteinizing hormone (LH) and follicle-stimulating hormone (FSH) to distinguish between ovarian and adrenal sources 2
• Measure serum prolactin, especially if testosterone is elevated with low/normal LH levels 2
• Consider dehydroepiandrosterone sulfate (DHEAS) measurement, particularly if testosterone is twice the upper limit of normal 1

Additional Testing Based on Initial Results

• If testosterone is markedly elevated (>5 nmol/L or showing signs of virilization), urgent investigation is needed to rule out androgen-producing tumors 3
• If DHEAS >600 mg/dl, suspect androgen-secreting adrenal cortical adenoma 1
• If clinical symptoms are present with normal testosterone, check sex hormone-binding globulin (SHBG) as it may be reduced in overweight patients or those with metabolic syndrome 1

Common Causes to Consider

1. Polycystic Ovary Syndrome (PCOS)

   • Most common cause of hyperandrogenism in young women 4
   • Characterized by menstrual irregularity, clinical hyperandrogenism, and/or polycystic ovaries

2. Late-onset Congenital Adrenal Hyperplasia

   • Consider in patients with family history or specific ethnic backgrounds
   • May require specialized testing (ACTH stimulation test)

3. Androgen-producing Tumors

   • Rare but serious cause, particularly if rapid onset of symptoms or virilization
   • Requires imaging studies (transvaginal ultrasound, MRI, or CT) 3

4. Other Causes

   • Hyperprolactinemia
   • Cushing's syndrome
   • Exaggerated adrenarche
   • Insulin resistance

Treatment Approach

For PCOS (Most Likely Diagnosis)

1. Lifestyle Modifications

   • Weight management and exercise for patients with overweight/obesity
   • Dietary counseling

2. Hormonal Management

   • Combined oral contraceptive pills - first-line therapy for menstrual irregularity and hyperandrogenism 2
   • Metformin - improves menstrual cyclicity and hyperandrogenism, particularly in patients with insulin resistance or metabolic concerns 2

3. Anti-androgen Therapy (if needed for persistent symptoms)

   • Consider after adequate trial of above treatments
   • Options include spironolactone, cyproterone acetate (where available)

For Androgen-producing Tumors

• Surgical intervention is the primary treatment 3
• Referral to appropriate specialist (gynecologic oncology, endocrinology, or urology)

For Late-onset Congenital Adrenal Hyperplasia

• Glucocorticoid replacement therapy
• Endocrinology referral

Monitoring and Follow-up

• Regular assessment of clinical symptoms (hirsutism, acne, menstrual patterns)
• Periodic measurement of testosterone levels to assess treatment efficacy
• Screening for metabolic complications (lipid profile, glucose tolerance)
• Assessment for psychological impact and quality of life

Special Considerations

• Fertility concerns should be addressed, particularly if planning pregnancy in the near future
• Screen for common comorbidities: insulin resistance, dyslipidemia, and mood disorders
• Consider the psychological impact of hyperandrogenism symptoms on body image and self-esteem

When to Refer

• Severe hyperandrogenism or signs of virilization
• Suspected androgen-secreting tumor
• Failure to respond to first-line treatments
• Complex endocrine disorders requiring specialized management

Remember that early diagnosis and appropriate management can significantly improve symptoms and prevent long-term complications associated with hyperandrogenism.
