From the Guidelines

Erectile dysfunction unresponsive to Sildenafil (Viagra) can be caused by various underlying health conditions, including cardiovascular disease, diabetes, prostate cancer, multiple sclerosis, and hormonal imbalances, as well as psychological factors like anxiety or depression, as noted in studies 1. When considering the causes of erectile dysfunction unresponsive to Sildenafil, it's essential to evaluate the patient's overall health and medical history. Factors such as:

  • Underlying health conditions like cardiovascular disease, diabetes, and prostate cancer
  • Hormonal imbalances, including low testosterone levels
  • Psychological factors like anxiety, depression, and stress
  • Medications or substances that may interfere with erectile function
  • Lifestyle factors, including smoking, excessive alcohol consumption, and lack of exercise can all contribute to erectile dysfunction that is unresponsive to Sildenafil. The most effective approach to addressing erectile dysfunction unresponsive to Sildenafil is to consult with a healthcare provider to determine the underlying cause and develop a personalized treatment plan, which may include alternative medications, lifestyle modifications, and addressing underlying health conditions, as recommended by the American College of Physicians 1.

From the Research

Causes of Erectile Dysfunction Unresponsive to Sildenafil (Viagra)

  • The provided studies do not directly address the causes of erectile dysfunction unresponsive to Sildenafil (Viagra) 2, 3, 4, 5, 6.
  • However, the studies suggest that Sildenafil is effective in treating erectile dysfunction of various etiologies, including vasculogenic, neurogenic, and psychogenic causes 2, 3, 5.
  • The studies also highlight the importance of considering underlying medical conditions, such as hypertension, coronary artery disease, and spinal cord injury, when treating erectile dysfunction with Sildenafil 4, 6.
  • Additionally, the studies note that Sildenafil may not be effective in all cases, and that other treatments, such as vardenafil and tadalafil, may be preferred by some patients 2.
  • The use of nitrates, alpha(1)-blockers, and other medications may also affect the efficacy and safety of Sildenafil, and should be considered when treating erectile dysfunction 4.
