Evaluation and Management of Elevated Testosterone in Adults

In adult patients with elevated testosterone, immediately measure DHEAS to differentiate adrenal from ovarian/testicular sources, and if testosterone is >2x the upper limit of normal or DHEAS >600 µg/dL (16,000 nmol/L), obtain urgent imaging to exclude androgen-secreting tumors. 1

Initial Diagnostic Approach

For Women with Elevated Testosterone

The evaluation must systematically exclude life-threatening and treatable conditions before attributing hyperandrogenism to PCOS 2:

Mandatory initial testing:

  • Pregnancy test if amenorrhea is present
  • Early morning total testosterone (repeat to confirm elevation)
  • DHEAS level - critical for source localization 1
  • Pelvic ultrasonography to detect ovarian neoplasms or polycystic ovaries
  • Prolactin to exclude hyperprolactinemia
  • Early morning 17-hydroxyprogesterone to exclude non-classic congenital adrenal hyperplasia 2

Critical thresholds requiring urgent action:

  • Testosterone >2x upper limit of normal warrants DHEAS measurement 1
  • DHEAS >600 µg/dL (16,000 nmol/L) indicates probable androgen-secreting adrenal adenoma requiring immediate abdominal CT/MRI 1
  • If DHEAS is normal but testosterone remains markedly elevated, consider ovarian hyperthecosis or ovarian tumor

Additional Testing Based on Clinical Context

Assess for Cushing's syndrome, thyroid dysfunction, or acromegaly only if other clinical features of these conditions are present 2.

In high-risk populations (Ashkenazi Jews, Hispanics, Slavics), measure early morning follicular phase 17-hydroxyprogesterone due to higher prevalence of congenital adrenal hyperplasia 2.

Assay Considerations

Timing and conditions matter critically:

  • Draw testosterone in early morning (diurnal variation is significant) 3
  • Verify menstrual cycle timing in women 1
  • Avoid testing during thyroid hormone therapy or medications affecting SHBG (antiepileptics like valproate) 1
  • Consider measuring SHBG when obesity, metabolic syndrome, or family history of diabetes is present, as reduced SHBG can falsely lower total testosterone interpretation 1

For Men with Elevated Endogenous Testosterone

Elevated endogenous testosterone (>800 ng/dL) in men is not associated with clinically significant morbidity and does not require intervention. 4

A 2022 study examining men with testosterone >800 ng/dL found:

  • No increased rates of sleep disorders, urinary symptoms, or depression
  • Slightly higher hematocrit (mean increase 1.30%), but not clinically significant
  • Modest elevations in AST and ALT without clinical liver disease 4

Key distinction: This applies only to naturally elevated endogenous testosterone, not exogenous testosterone therapy. When testosterone >40 nmol/L (>1,150 ng/dL), consider exogenous administration or abuse 3.

Management Algorithm

If Tumor Suspected (Testosterone >2x Normal or DHEAS >600 µg/dL):

  1. Urgent imaging (CT or MRI of abdomen/pelvis)
  2. Refer to endocrinology and surgical oncology
  3. Do not delay imaging for additional testing

If PCOS Suspected (Normal DHEAS, Polycystic Ovaries, Anovulation):

  1. Confirm diagnosis requires testosterone elevation + anovulatory symptoms or polycystic ovary 2
  2. For patient-important hirsutism: offer pharmacological therapy or direct hair removal based on patient preference, extent of affected area, and access 2
  3. Address metabolic complications (insulin resistance, dyslipidemia)

If Ovarian Hyperthecosis Suspected (High Testosterone, Normal DHEAS, Insulin Resistance):

  • Testosterone elevation is LH-dependent
  • Responds to GnRH agonist, estrogen-progestogen, or cyproterone acetate 1
  • Consider endocrinology referral for hormonal suppression

Common Pitfalls to Avoid

Do not assume PCOS without excluding neoplasms - this is the most dangerous error. Even moderate hirsutism with elevated testosterone requires systematic exclusion of tumors 2.

Do not rely on single testosterone measurement - testosterone fluctuates markedly day-to-day and seasonally 3. Confirm with repeat early morning testing.

Do not overlook normal testosterone with clear hyperandrogenic symptoms - measure free testosterone or calculate bioavailable testosterone in reliable specialty laboratory 2, 1. SHBG alterations can mask true androgen excess.

Do not forget to check for medication effects - estrogenic medications (tamoxifen, raloxifene), hyperthyroidism, or liver disease can markedly elevate SHBG, creating spuriously elevated total testosterone 1.
