Evaluation of ejaculatory dysfunction

Asking a patient about his personal history is generally the first step a physician takes in diagnosing and evaluating ejaculatory dysfunctions. This can reveal if the problem has always been present, which may indicate if it is due to a birth defect or to an acquired condition.

Elements of evaluation include:

  • Physical exam of the genitalia and testicles for structural problems
  • Semen sample for evaluation of sperm presence and health
  • Post-ejaculate urine sample if no ejaculate was produced
  • Hormonal testing
  • Transrectal ultrasound (TRUS) to look for structural problems.
