Influence of Paternal Age on Assisted Reproduction Outcome

In the recent years, there is an increasing tendency to the parenthood delay in developed countries, and there is not enough information available regarding the influence of the male's age on fertility. If any, the negative impact should be acting at advanced ages. Our aim with this work was to determine the role of paternal age on IUI results embryo quality and IVF outcome. Evenmore, in order to standardize the female factor, good quality oocytes (from fertile oocyte donors) and only first IVF cycles in young women were considered.
