title: Aromatase inhibition for the treatment of idiopathic hypogonadotropic hypogonadism in men with premature ejaculation.
abstract: BACKGROUND
  Idiopathic hypogonadotropic hypogonadism (IHH) has been observed to occur in men with premature ejaculation (PE). Common IHH therapies include testosterone replacement, which increases testosterone levels but suppresses gonadotropin release; and gonadotropin-releasing hormone supplementation, which restores gonadotropin levels but is impractical for chronic use. Hormonal imbalances associated with IHH/PE are thought to be related to hyperactivity of the cytochrome P-450 enzyme aromatase.
  
  
  METHODS
  Ten male patients with a diagnosis of IHH/PE were treated with the aromatase inhibitor anastrazole (1 mg/d orally). Levels of free and total testosterone, luteinizing hormone, follicle-stimulating hormone, prolactin, and estradiol were determined at baseline and after 2 weeks of therapy.
  
  
  RESULTS
  After 2 weeks of therapy with anastrazole, levels of testosterone, luteinizing hormone, and estradiol had returned to normal. No effect was noted on premature ejaculation.
  
  
  CONCLUSIONS
  These results suggest that aromatase inhibition with anastrazole may provide a practical and efficacious alternative for the treatment of IHH but is not effective in preventing premature ejaculation.
