Background: Oocyte donation has become widely used as a treatment option for infertile couples. The few available studies report conflicting evidence about the risk of hypertensive disorders in donor oocyte pregnancies after adjusting for maternal age and it is unclear whether pregnancy complications and obstetric risks are due to oocyte donation or to confounding factors such as maternal age. The aim of the present study was to evaluate and compare obstetric complications between women who conceived after oocyte donation and age-matched control women with spontaneous conception and self oocyte IVF conception.

Methods : The present study comprised of women aged 20-45 years conceived from oocyte donation (n=104) between 1/12/2010 to 15/10/2017. Two age-matched control groups—Self oocyte IVF (n=150) and the other containing women who conceived spontaneously (n=312) were used for comparison of obstetric and perinatal outcomes.

Results: Mean maternal age was statistically significantly higher in the Donor oocyte IVF group as compared to  self oocyte ivf and spontaneous conception group. Miscarriage, first trimester bleeding, pregnancy induced hypertension and gestational diabetes mellitus was significantly higher in Donor oocyte IVF group as compared to self-oocyte and spontaneous conception group (p=0.001). Using multiple logistic regression analysis age class adjusted PIH and GDM  incidence was significantly higher in donor oocyte group as compared to spontaneous conception (P=0.010).There was significant variation in perinatal outcomes between the three groups.

Conclusion: Oocyte donation should be treated as an independent risk factor for miscarriage, first trimester bleeding, hypertensive disorder and gestational diabetes mellitus in pregnancy.
