Diagnostic Approach and Treatment for Elevated Testosterone

Initial Evaluation and Monitoring

Measure serum luteinizing hormone (LH) levels to help establish the etiology of testosterone abnormality, particularly in patients with abnormal testosterone levels, as recommended by the American Urological Association 1
Measure serum prolactin levels, particularly in patients with abnormal LH levels to screen for hyperprolactinemia, as suggested by the American Urological Association 1
Measure serum estradiol in patients who present with breast symptoms or gynecomastia, as recommended by the American Urological Association 2
Assess hemoglobin/hematocrit levels, as elevated testosterone can lead to erythrocytosis, according to the New England Journal of Medicine 3
Regular measurement of testosterone levels to assess treatment efficacy, as recommended by the American Urological Association 1
Monitor hemoglobin/hematocrit, as high testosterone can cause erythrocytosis, according to the New England Journal of Medicine 3
In men, monitor PSA levels (if age >40) to screen for prostate abnormalities, as recommended by the American Urological Association 2

Surgical removal of the tumor is the primary treatment for tumors (adrenal, testicular, ovarian, pituitary), as recommended by the American Urological Association 1
Follow-up monitoring of testosterone levels after surgery for tumors (adrenal, testicular, ovarian, pituitary), as recommended by the American Urological Association 1
Consider the impact on fertility when treating testosterone abnormalities, as recommended by the American Urological Association 2

High testosterone can cause adverse effects including erythrocytosis, aggressive behavior, and metabolic disturbances, according to the New England Journal of Medicine 3
Men with significantly abnormal testosterone levels should undergo pituitary MRI regardless of prolactin levels, as non-secreting adenomas may be present, as recommended by the American Urological Association 1
Treatment approaches should consider the patient's fertility goals, as some treatments may impair fertility, as recommended by the American Urological Association 2
Hormone levels can fluctuate; confirmation of abnormal results is essential before initiating treatment, as recommended by the American Urological Association 1
