Physical aspects of erectile dysfunction


This may be due due to nerve damage, e.g. damage to perineal nerve, pudendal nerve, nervi erigentes or pelvic splanchnic nerves etc. It is a parasympathetic effect and the nerve supply is in the pelvic parasympathetic sacral outflow  (S2-4). It is mainly affected by the loss of nerve supply or function of the ischiocavernosus which helps in erection of the penis or clitoris at sexual arousal and during sexual intercourse.

Other factors which may be said to be physical include

  • Cardiovascular diseases

  • Diabetes mellitus

  • Endocrine disorders

  • Alcohol

  • Substance abuse
