title: Effect of a selective nonsteroidal anti-inflammatory drug, celecoxib, on the reproductive function of female mice.
abstract: BACKGROUND
  The aim of the present study was to determine if long-term use of a cyclooxygenase-2 (COX-2) inhibitor affects fertility or ovulation in female mice.
  
  
  METHODS
  Twenty-four female mice, 25 days of age, were given a selective COX-2 inhibitor: 3 mg/kg celecoxib (n = 8), 5 mg/kg celecoxib (n = 8),or placebo (n = 8) in a random fashion. Eight female mice, 10-11 weeks old, given 3 mg/kg celecoxib (n = 4) or placebo (n = 4) were subjected to continuous mating studies.
  
  
  RESULTS
  Results from the 24 mice (n = 8 for each group) showed that oocyte number was not significantly different between female mice treated with either 3 mg/kg or 5 mg/kg celecoxib and placebo (21.4 +/- 2.5, 21.5 +/- 3.3, 23.3 +/- 3.8, respectively). From the continuous mating study, the litter size of female mice treated with celecoxib was not significantly different (8.2 +/- 1.3 pups/litter) compared to those treated with placebo (8.3 +/- 1.2 pups/litter). In addition, female mice treated with celecoxib had an average of 2.8 +/- 0.5 litters in a 12-week period, which was similar to female mice treated with placebo (3.0 +/- 0.8 litters/female).
  
  
  CONCLUSIONS
  This study suggests that use of low-dose (<or= 5 mg/kg) selective COX-2 inhibitor in a mouse model does not significantly impair the female reproductive function.
