The influence of female age on the cumulative live-birth rate of fresh cycles and subsequent frozen cycles using vitrified blastocysts in hyper-responders

Objective: The aim of this research was to study the influence of female age on the cumulative live-birth rate of fresh and subsequent frozen cycles using vitrified blastocysts of the same cohort in hyper-responders. Materials and methods: This was a retrospective study of 1137 infertile women undergoing their first in vitro fertilization treatment between 2006 and 2013. The main outcome measure was cumulative live births among the fresh and all vitrified blastocyst transfers combined after the same stimulation cycle. The results were also analyzed according to age (i.e.,
