Psychological problems cause erectile dysfunction by reducing the physical responses needed to get a strong erection in various ways:

  • Stress reduces blood flow to the penis

 

  • Anxiety reduces testosterone

 

  • Depression affects sex drive and response

 

  • Low mood suppresses neurochemicals like dopamine needed for orgasm

 

  • Anti-depressant medications  affect libido and  sexual response

 

  • Poor emotional health affects relationships
