Erectile dysfunction is a problem with multiple causes and is challenging to diagnose. Chronic pain has been associated with erectile dysfunction in some studies. Chronic pain can be a potential direct or indirect cause of sexual dysfunction. A decreased sexual desire due to restricted sexual activity in chronic pain can result in erectile dysfunction. Erectile dysfunction has been linked to migraines, chronic pain, and psychological factors. Multiple neurotransmitters may contribute to the pathophysiology of erectile dysfunction. Depression and anxiety, as well as painkillers like pregabalin and opioids, can be indirect causes of erectile dysfunction. Numerous factors affect the occurrence of erectile dysfunction; therefore, erectile dysfunction must be treated holistically.
