Paternal Age May Also Affect ICSI Outcome in Oligozoospermic Patients

Paternal Age May Also Affect ICSI Outcome in Oligozoospermic Patients
May 15, 2009
Maternal age has been identified as a key determining factor in the success rates of IVF/ICSI procedures; however, relatively few studies have investigated the effect of advanced paternal age on ICSI outcome. Now, a recent retrospective observational study, published in the journal, Fertility and Sterility, suggests the negative effect of increased paternal age of oligozoospermic patients on implantation rate after ICSI. The study reports a 5% decrease in the chances of pregnancy for such couples with each year of increase in paternal age.
