title: Contribution of male age to outcomes in assisted reproductive technologies.
abstract: OBJECTIVE
  To evaluate the relationship between male age and pregnancy outcome in donor oocyte assisted reproductive technology cycles.
  
  
  METHODS
  Retrospective cohort.
  
  
  METHODS
  Private IVF center.
  
  
  METHODS
  A total of 1,392 donor cycles from 1,083 female recipients and their male partners.
  
  
  METHODS
  Oocyte donor cycles.
  
  
  METHODS
  Live birth.
  
  
  RESULTS
  Increasing male age was associated with semen parameters including volume and motility; however, male age was not observed to have a statistically significant association with likelihood of live birth in donor cycles after adjustment for female recipient age.
  
  
  CONCLUSIONS
  When treatment cycle number and female recipient age were taken into account, male age had no significant association with pregnancy outcomes in assisted reproductive technology donor cycles in this study population.
