From the Guidelines

Referral for further evaluation is recommended for a 34-year-old male with normal testosterone levels and erectile dysfunction symptoms if there are signs of underlying cardiovascular disease or other health conditions that may warrant evaluation and treatment.

Key Considerations

  • According to the American Urological Association (AUA) guideline 1, men presenting with symptoms of erectile dysfunction (ED) should undergo a thorough medical, sexual, and psychosocial history, a physical examination, and selective laboratory testing.
  • The AUA guideline also recommends that men with ED should be counseled that ED is a risk marker for underlying cardiovascular disease (CVD) and other health conditions that may warrant evaluation and treatment 1.
  • The Princeton III consensus recommendations suggest that all men with ED should have their cardiovascular risk assessed, and testosterone level should be routinely measured 2, 3.
  • The evaluation and management of testosterone deficiency guideline by the AUA recommends that clinicians should use a total testosterone level below 300 ng/dL as a reasonable cut-off in support of the diagnosis of low testosterone, but also emphasizes the importance of symptoms and signs in making the diagnosis 4.
  • The American College of Physicians guideline on hormonal testing and pharmacologic treatment of ED found that the prevalence of low testosterone levels in men with ED varied widely across studies, and the value of routine hormonal testing for the evaluation of ED is unclear 5.

Referral Criteria

  • Presence of signs or symptoms suggestive of underlying cardiovascular disease, such as hypertension, dyslipidemia, or diabetes.
  • Presence of other health conditions that may warrant evaluation and treatment, such as hypogonadism, sleep apnea, or depression.
  • Failure to respond to initial treatment for ED, such as phosphodiesterase-5 inhibitors.
  • Presence of significant psychological or psychosocial factors contributing to ED, such as anxiety, depression, or relationship issues.

Next Steps

  • Refer the patient to a cardiologist or primary care physician for further evaluation of cardiovascular risk factors.
  • Consider referral to a mental health professional for evaluation and treatment of psychological or psychosocial factors contributing to ED.
  • Continue to monitor the patient's testosterone levels and overall health status, and adjust treatment as needed.

From the Research

Referral for Further Evaluation

When to refer a 34-year-old male with normal testosterone levels and erectile dysfunction symptoms for further evaluation:

  • The patient's normal testosterone levels do not necessarily rule out the possibility of underlying conditions contributing to erectile dysfunction, as erectile dysfunction can be caused by multifactorial pathologies 6.
  • It is recommended to assess testosterone levels in all patients with erectile dysfunction, regardless of age or initial testosterone level 6, 7.
  • Testosterone replacement therapy may be beneficial for men with hypogonadism and erectile dysfunction, and may also improve response to phosphodiesterase type 5 inhibitors in men with low-normal serum testosterone 7, 8, 9.
  • Given the patient's age (34 years old), it is essential to consider age-specific normative values and cutoffs for testosterone levels, as young men have different testosterone reference ranges than older men 10.
  • The patient should be referred for further evaluation to rule out underlying conditions such as cardiovascular disease, which may be the first symptom of erectile dysfunction 6.
  • A comprehensive evaluation, including medical history, physical examination, and laboratory tests, should be performed to determine the underlying cause of erectile dysfunction and to develop an appropriate treatment plan 8.
