title: Hypertension as a complication of topical testosterone therapy.
abstract: OBJECTIVE
  To report a patent developing hypertension following the use of testosterone gel.
  
  
  METHODS
  A 65-year-old white man who was placed on topical testosterone therapy to increase libido developed hypertension and increased hematocrit simultaneously. After discontinuation of the testosterone, the hematocrit returned to mid-normal reference range and blood pressure returned to normal; he had been normotensive prior to topical testosterone use.
  
  
  CONCLUSIONS
  The popularity of hormone replacement for women for the maintenance of appearance and lifestyle and the prevention of complications such as osteoporosis has been established over several decades, and the complications and risks and benefits of this therapy have been well described. More recently, and particularly with the availability of topical preparations of testosterone, hormone replacement for men is becoming popular with both older male patients and their physicians. We describe a case of hypertension as a complication of the application of topical testosterone and link this adverse effect to the known anabolic effects of testosterone.
  
  
  CONCLUSIONS
  Clinicians should be cautious in prescribing topical preparations of testosterone for the proper administration by the patient and alert to the development of hypertension in this population at increased risk for cardiovascular events due to their age.
