Oocyte donation is an independent risk factor for pregnancy complications: the implications for women of advanced age.

Abstract

Maternal age at first pregnancy and age-related infertility are steadily increasing, and the demand for assisted reproductive technologies (ART) to treat age-related infertility is also on the rise. The latest registry findings from Europe and the United States show that the meager results of ART in women above 43 years of age have not improved much over the past 10 years. The latest evidence shows that the demand for oocyte donation (OD) is steadily increasing. Contrary to previous belief-attributing increased perinatal complications in OD recipients to advanced maternal age and multifetal pregnancy-accumulating evidence from the past few years suggests that OD itself is a significant and independent risk factor for pregnancy complications, mostly for pre-eclampsia. The increased rate of chronic maternal disease and medical complications in pregnancy observed in advanced maternal age, coupled with the growing demand for OD, with its independent association with pre-eclampsia, create an urgent need to adopt a clear policy taking these risks into account. We present recent evidence showing that OD is an independent risk factor for pre-eclampsia and suggest recommendations for women approaching OD treatment in advanced age.
