Abstract

ABSTRACT Introduction Prior to the era of in vitro fertilization, no options for conception were available to women with primary ovarian insufficiency, decreased ovarian reserve, or genetically transmittable diseases. Oocyte donation (OD) has been used in such women for almost 30 years. It also offers an opportunity to study the participation of the uterus in the process of human embryo implantation. Aim To identify recipient variables that may have a significant impact on the pregnancy outcome of an OD program. Materials and methods The present study was conducted at Madras Medical Mission Hospital, Chennai, India. We retrospectively evaluated 192 patients and 283 embryo transfer cycles as a result of OD over a period of 5 years. Rates of implantation, clinical pregnancy, ongoing pregnancy, miscarriage, and live birth were calculated for different age groups, endometrial thickness (ET), indications of OD, fresh and frozen embryo transfers (FET), type of subfertility, past history of endometriosis, and body mass index (BMI) of the recipients. Data evaluation was mainly done by Chi-square analysis, and receiver operating characteristic (ROC) curves were made for age and ET. Results The results of this study showed a clinical pregnancy rate (CPR) of 37.1%, implantation rate (IR) of 19.3%, miscarriage rate of 20.4%, ongoing pregnancy rate (OPR) of 32.2%, and live birth rate (LBR) of 26.6%. Significant association was seen between age of recipient and OPR (p = 0.014), and also between fresh embryo transfers, CPR, OPR, and LBR (p < 0.05). The ROC curves showed a significant association of LBR with age of recipient. Conclusion Although no single or combined recipient variable(s) could be identified as predictor(s) of pregnancy, significant association was found between OPR, LBR, and recipient's age and also between fresh embryo transfers with CPR, OPR, and LBR.
