title: Standards for genital protection in phototherapy units.
abstract: BACKGROUND
  Phototherapy is a useful therapy for many dermatologic disorders and is known for its low side-effect profile. However, one potential notable side effect is genital skin cancer. Unfortunately, no standards for genital protection currently exist for this preventable complication. Patients treated with phototherapy may already have a decreased quality of life because of their primary dermatologic disorder. Development of squamous cell carcinoma of the genitalia may certainly further affect the quality of life.
  
  
  OBJECTIVE
  The objective was to determine which readily available materials afford the best photoprotection of the male genitalia.
  
  
  METHODS
  Seven common materials used in phototherapy units for genital protection were placed over ultraviolet (UV) B and UVA monitors and placed in broadband UVB, narrowband UVB, and UVA full-body units. The percentage of light blocked was then calculated.
  
  
  RESULTS
  Blue and white cotton underwear, blue surgical towels, an athletic supporter with or without a cup, and the psoralen plus UVA pouch provided acceptable means of genital protection; however, surgical masks did not.
  
  
  CONCLUSIONS
  Only the most commonly used materials were tested in the phototherapy units. The materials were not of a single material type or similar masses. In addition, only one of each type of full-body phototherapy unit was used to obtain the data.
  
  
  CONCLUSIONS
  Although a polyester composition provides better UV protection, factors such as low porosity and higher mass are intrinsic to decreasing the amount of UV penetration of any fabric. Of the commonly used objects, surgical masks do not provide sufficient protection to the genital area.
