title: The impact of sildenafil on molecular science and sexual health.
abstract: OBJECTIVE
  Sexual medicine has evolved greatly in the past several years, to a large extent because of the introduction of the phosphodiesterase-5 (PDE5) inhibitor, Viagra (sildenafil citrate), as a highly effective oral therapy for erectile dysfunction.
  
  
  METHODS
  Recent literature pertaining to the development and clinical applications of sildenafil citrate was reviewed.
  
  
  RESULTS
  The emergence of PDE5 inhibitor therapy for erectile dysfunction represents a major scientific and clinical breakthrough, and it has impacted on the field in such prominent areas as scientific discovery, clinical management, and public health awareness of sexual health disorders.
  
  
  CONCLUSIONS
  The development of sildenafil citrate has had a major role in advancing the field of sexual medicine.
