Paternal age has a significant effect on cumulative live birth rates (clbr) per inseminated oocyte, embryo transfer (et) and embryo transferred in ivf-icsi with donated oocytes

Due to current fatherhood delay, studies relating paternal age with reproductive outcomes are increasing being results controversial and more research about it necessary. Studies considering donated oocytes control for female factor allowing a better understanding of male contribution. This study aims to assess paternal age effect on reproductive results in terms of CLBR per inseminated oocyte, ET and embryo transferred in donor IVF-ICSI to better measure the involvement of paternal age by taking into account the contribution of all the embryo cohort.
