Comparison of Obstetric Outcomes of Pregnancies after Donor-Oocyte In vitro Fertilization and Self-Oocyte In vitro Fertilization: A Retrospective Cohort Study

AIMS: The aim of this study is to evaluate and compare multiple obstetric and perinatal outcomes between donor-oocyte in vitro fertilization (IVF) and self-oocyte IVF group. SETTINGS AND DESIGN: This study was done in a tertiary care center with ART unit. This was a retrospective comparative cohort study. MATERIALS AND METHODS: The present study comprised all women between 20 and 45 years who conceived from oocyte donation (n = 78) between December 1, 2010, and December 31, 2016, and compared with all women who underwent self-oocyte IVF (n = 112). The process involved controlled ovarian stimulation and retrieval of the donor oocytes, preparation of recipient endometrium, and pregnancy management. Obstetric and perinatal outcomes were compared. STATISTICAL ANALYSIS USED: Chi-square test was used for categorical variables. Analysis for confounding variables was performed using multivariable linear and logistic regression analysis. RESULTS: Baseline characteristics between the two groups were comparable. Miscarriage, first-trimester bleeding, pregnancy-induced hypertension (PIH), and gestational diabetes mellitus were significantly higher in donor-oocyte IVF group compared to self-oocyte cycles (P = 0.001). Using multiple logistic regression analysis, age class adjusted PIH incidence was significantly higher in donor-oocyte group as compared to self-oocyte group (P = 0.010). There was no significant variation in perinatal outcomes between the donor- and self-oocyte IVF cycles (P > 0.05). CONCLUSION: Oocyte donation should be treated as an independent risk factor for PIH.
