Background: Oocyte donation is an invaluable therapy for couples with impending or complete ovarian failure. In addition, oocyte donation affords a scientific opportunity to study the unique biologic participation of the uterus in the process of human embryo implantation. Aim: To identify the recipient variables that may have a significant impact on pregnancy outcome in order to optimize results of an oocyte donation program. Design and Settings: A prospective study conducted from March 1, 2010 to March 31, 2011 at a private tertiary care IVF Clinic. Materials and methods A total of 270 recipients resulting in embryo transfer as a result of oocyte donation were enrolled. Clinical and Ongoing pregnancy rates, Implantation rates were calculated according to different age groups, Endometrial thickness, Indication, Day and number of embryos transferred. Data was evaluated as chi square analyses with comparative significance determined at P <.05. Results: In recipients less than 40 years of age, higher ongoing pregnancy and implantation rates (41.9% and 24.6%) were seen as compared to recipients above 40 years (21.8% and 13.18%) respectively. Pregnancy and implantation rates increased with increasing endometrial thickness but the difference was not statistically significant. A higher ongoing pregnancy rate (40.9% vs.28.8%) and implantation rate (23% vs.19.6%) was demonstrated with Day 3 embryo transfer compared to Day 2 transfer. Conclusion: A declining endometrial receptivity may result in lower implantation and pregnancy rates in recipients above the age of 40 years, more pronounced after the age of 45 years. An endometrial thickness of >8 mm is considered ideal before transfer. Transfer of two selected embryos on day 3 yields a favorable pregnancy outcome with reduced multiple pregnancy rates. Recipient's age above 45 years has negative impact on pregnancy outcome whereas embryo transfers on Day 3 yields better pregnancy
