Abstract
Purpose: To study effect of paternal age on pregnancy outcomes of intracytoplasmic sperm injections (ICSI). Methods: The present study is a retrospective analysis of 153 ICSI cycles on donor oocytes. The effect of paternal age on fertilization rates, implantation rates, total pregnancy rates, number of miscarriages and live births were analyzed. Results: 1422 donor oocytes were injected with sperm from 153 men. Linear regression analysis revealed no association between paternal age (28-54 years) and fertilization rate. No association was found between the embryo quality and paternal age. Of the 359 embryos transferred, linear regression analysis revealed no association between paternal age and implantation rate. After correcting for maternal age, binary logistic regression analysis revealed no association between total pregnancy rates (B = 0.943, CI 0.861-1.033, P = 0.205), live birth rates (B = 1.018, CI 0.896-1.158, P = 0.562) and miscarriage rates (B = 0.944, CI 0.866-1.029, P = 0.193) and paternal age. Conclusion: Paternal age does not seem to influence outcomes in assisted reproduction.
