The age of parenthood has been steadily increased during the last decades, so it is very important to study the influence of aging, especially male aging on reproductive outcomes.We retrospectively analyzedthe data of intracytoplasmic sperm injection (ICSI) cyclesin the Reproductive Medicine Center of the Third Affiliated Hospital of Guangzhou Medical University between January 2007 and October 2013.Multiple linear regression was used to analyze the effect of male age on embryo quality (number of fertilized ooeytes, 2PNs,useful embryos and high-quality embryos).Relationship between male age and pregnancy outcomes (clinical pregnancy, ongoing pregnancy, miscarriage and live birth) was analyzed by binary logistic regression.There were totally 2584 cycles included in this study.There was no association between male age and any parameters of embryo quality.Male age had no effect on pregnancy outcomes: clinical pregnancy(OR 0.949;95% CI 1.103-1.535) (P=0.205);oingoing pregnancy (OR 0.972;95% CI 0.812-1.164) (P=0.759);miscarriage ((OR 1.047;95% CI 0.862-1.272) (P=0.645) and live birth (OR 0.970;95% CI 0.886-1.062) (P=0.511).Male age had no impact on embryo quality as well as pregnancy outcomes in ICSI cycles.
