Live birth rate (%) as a function of average daily gonadotropin dose, stratified by number of oocytes retrieved and age. Differences were significant at p<0.0001 across oocyte groups within FSH dose categories, and within oocyte groups across FSH dose categories for all ages and within each age group.
