title: Effect of high environmental temperature on semen parameters among fertile men.
abstract: OBJECTIVE
  To evaluate the effect of high environmental occupational temperature on semen parameters of fertile men.
  
  
  METHODS
  Prospective.
  
  
  METHODS
  Steel-casting plant.
  
  
  METHODS
  Ninety fertile workers exposed to a high temperature compared with 40 fertile workers working under ordinary conditions as control subjects.
  
  
  METHODS
  Measurement of scrotal temperature by invagination thermometry, air temperature, relative humidity by aspirated psychrometer, radiant heat by globe thermometer, air velocity by light vane anemometer, and semen analysis.
  
  
  METHODS
  Scrotal temperature and semen analysis.
  
  
  RESULTS
  Nonsignificant difference was found between the two groups regarding their scrotal temperature. Also, nonsignificant differences were demonstrated regarding semen analysis parameters being in the normozoospermic range.
  
  
  CONCLUSIONS
  Under high environmental temperature, semen parameters were within normozoospermic levels owing to body acclimatization mechanisms.
