What are the diagnostic tools used for erectile dysfunction?

These diagnostic tools include:
  • nocturnal penile tumescence monitoring—this a test that measures the rigidity of an erection with sensing probes placed against the sides of the penis;
  • duplex doppler ultrasound—evaluates blood flow as it moves through vessels;
  • somatosensory evoked potentials—measures the signals that show whether nerves send and receive sensory information;
  • caversonometry and caversonography—determines if an erection disorder results from poor blood circulation as a result of blood leaks;
  • arteriography—evaluates the number and severity of blockages in arteries;
  • psychological assessment—uncovers behavior patterns that affect erectile function;
  • endothelial assessment—examines peripheral endothelial function by peripheral arterial tonometry (PAT).
