title: Celiac disease is not a risk factor for infertility in men.
abstract: OBJECTIVE
  To examine fertility in men with biopsy-verified celiac disease (CD) in light of research that suggests that men with CD have impaired sperm quality.
  
  
  METHODS
  Using multinomial logistic regression and Cox regression, we estimated the fertility of the study group compared with that of 31,677 age-matched reference male controls.
  
  
  METHODS
  Sweden.
  
  
  METHODS
  Swedish nationwide population-based cohort of 7,121 men with CD (defined according to duodenal-jejunal biopsy data with [Marsh III] villous atrophy) ages 18-54 years at some point before the end of follow-up.
  
  
  METHODS
  Number of children according to the Swedish Multi-Generation Register.
  
  
  RESULTS
  During follow-up, men with CD had 9,935 children compared with 42,245 among controls. Adjusting for age, calendar period, and parity and stratifying by education, the overall fertility hazard ratio in the men with biopsy-verified CD was 1.02 (95% confidence interval, 0.99-1.04).
  
  
  CONCLUSIONS
  This study found a normal fertility in men with diagnosed CD.
