title: Effect of age on serum prolactin concentration in presumably fertile men in Sri Lanka.
abstract: OBJECTIVE
  To examine possible age related variation in serum prolactin in men.
  
  
  METHODS
  A cross sectional study.
  
  
  METHODS
  Healthy married men aged 21 to 85 years with one or more children.
  
  
  METHODS
  Serum prolactin concentrations measured by immunoradiometric assay.
  
  
  RESULTS
  Prolactin concentrations were significantly higher (p < 0.001) from 61 years of age onwards when compared with 31 to 60 years. Prolactin concentrations between 21 to 30 years were significantly higher than between 31 to 50 years (p < 0.05), but lower than between 61 to 70 (p < 0.05) and 75 to 85 (p < 0.01) years.
  
  
  CONCLUSIONS
  Serum prolactin concentrations show age related variations in presumably fertile men.
