In this single-center matched-cohort study, women who underwent IVF/ICSI with donor oocytes between 2007 and 2014 (n = 259) were compared to women undergoing autologous cycles during the same time period (n = 515). The matching (1:2) took into consideration the women's age, type of treatment (IVF/ICSI), and year of embryo transfer. All women were healthy and below 40 years of age at the time of IVF/ICSI, and the treatments were performed using a strict policy of single embryo transfer. Multiple logistic regression analysis, adjusted for body mass index (BMI), smoking, and parity, showed a four times increased risk of gestational hypertensive disorders (adjusted odds ratio, AOR 4.25; 95% confidence interval (CI), 2.61-6.92) and pre-eclampsia (AOR 3.99; 95% CI 2.27-7.00) in pregnancies achieved with donor oocytes. There was also a higher rate of cesarean section in women who gave birth after oocyte donation (AOR 1.69; 95% CI 1.22-2.35) and a higher risk of postpartum hemorrhage >1000 mL (AOR 1.59; 95% CI, 1.11-2.27). After further adjustment for preeclampsia in the logistic regression analysis, no additional increased perinatal risks were found. The incidence of preterm delivery, low weight at birth, need of neonatal intensive care, Apgar scores, and incidence of perinatal death were also similar between the groups.
