Male age influences oocyte-donor program results.

Background: The purpose of our research was to examine the relationship between male age and semen parameters in a range of ages (from 20s to 60s) in Egg Donation Program (EDP) cycles. EDP provides a pool of high quality oocytes, thus allowing better analysis of the sperm efficacy.

Discussion: The retrospective study population consisted of 484 male partners of patients undergoing EDP in in-vitro fertilization (IVF) treatments.
