Q

What is the conceptual model for sexual dysfunction in MS

A
  • primary sexual dysfunction: physiological impairments directly due to demyelinating lesions in the spinal cord and brain
  • secondary sexual dysfunction: non-sexual physical changes which affect the sexual response indirectly
  • tertiary sexual dysfunction: psychological, social and cultural issues that may affect sexual functioning
