BioNews - IVF using donor eggs increases preeclampsia risk, study claims: Pre-eclampsia is a common medical condition that affects between 2-8 percent of women during pregnancy and is associated with high blood pressure, increased protein in the urine and other symptoms. The cause is not fully understood but it is thought to be linked to problems with the placenta. The incidence remains the same for natural pregnancies and those following IVF treatment where the patient's own eggs were used.
Previous studies have indicated that women who use donor sperm and those who get pregnant with a new partner have higher rates of pre-eclampsia than other women, suggesting the condition could be related to an immune response against cells the body sees as foreign.
