*8.3. Oocyte Donation*

The increased risk of preeclampsia with assisted conceptions was shown to be attributable to advanced maternal age and oocyte donation [81,82]. The influence of oocyte donation as a risk factor is in alignment with disrupted immunological tolerance, as previously postulated, until one considers that women who conceive by egg donation tend to be older, a ffected by premature ovarian failure, or have mosaic Turner syndrome—and all these factors are known to increase cardiovascular risk [83,84].
