There appears to be a slightly higher risk of pregnancy-induced hypertension in pregnancies of egg donation. Fetus
Pregnancies with egg donation are associated with a slightly increased risk of placental pathology. The local and systemic immunologic changes are also more pronounced than in natural pregnancies, so it has been suggested that the association is caused by reduced maternal immune tolerance towards the fetus, as the genetic similarity between the carrier and fetus from an egg donation is less than in a natural pregnancy. In contrast, the incidence of other perinatal complications, such as intrauterine growth restriction, preterm birth and congenital malformations, is comparable to conventional IVF without egg donation. Custody
Generally legal documents are signed renouncing rights and responsibilities of custody on the part of the donor. Most IVF doctors will not proceed with administering medication to any donor until these documents are in place and a legal "clearance letter" confirming this understanding is provided to the doctor. Legality and financial issues
The legal status and cost/compensation models of egg donation vary significantly by country.
