Short answer:<\/strong> Yes. Research suggests that pregnancies conceived with donor eggs have a higher risk of preeclampsia than pregnancies conceived with a patient\u2019s own eggs, including pregnancies conceived through IVF. This increased risk is important to discuss with your fertility specialist and obstetric provider, but it does not mean that preeclampsia will occur. Many people who conceive with donor eggs have healthy pregnancies.<\/p>\n

What is preeclampsia?<\/h2>\n

Preeclampsia is a pregnancy complication involving new high blood pressure and signs that organs such as the kidneys or liver may be affected. It typically develops after 20 weeks of pregnancy, although it can also occur after delivery.<\/p>\n

According to the U.S. Centers for Disease Control and Prevention<\/a>, preeclampsia affects about 2% to 8% of pregnancies overall. Some people have no noticeable symptoms, which is one reason regular prenatal blood-pressure checks are so important.<\/p>\n

How much higher is the risk with donor eggs?<\/h2>\n

Studies have consistently found a higher relative risk of hypertensive disorders in pregnancies created with donated eggs. A systematic review and meta-analysis published in the American Journal of Obstetrics and Gynecology<\/em> found that the odds of preeclampsia were higher after oocyte donation than after other assisted-reproduction treatments. Another systematic review reported a higher risk in both singleton and multiple pregnancies conceived with donor eggs.<\/p>\n

The exact absolute risk for one pregnancy cannot be determined from the egg source alone. Risk varies with the person carrying the pregnancy, including age, prior pregnancy history, blood pressure, kidney health, diabetes, body weight, autoimmune conditions, whether this is a first pregnancy, and whether more than one baby is being carried.<\/p>\n

It is also important to understand that most available evidence is observational. These studies can identify an association, but they cannot always separate the effect of donor eggs from every other difference between patient groups.<\/p>\n

Why might donor egg pregnancies have a higher risk?<\/h2>\n

Researchers are still studying the reason. One proposed explanation involves how the pregnant person\u2019s immune system adapts to the placenta. In a donor egg pregnancy, the embryo\u2019s genetic material is fully different from that of the person carrying the pregnancy. That may influence placental development and immune tolerance.<\/p>\n

Other factors may contribute as well. People who use donor eggs may be older or may have medical conditions that independently increase pregnancy risk. The way the uterine lining is prepared for a frozen embryo transfer may also matter in some circumstances. No single explanation applies to every donor egg pregnancy.<\/p>\n

Does donor egg IVF automatically make a pregnancy high risk?<\/h2>\n

Not necessarily. \u201cHigher risk\u201d is not the same as \u201chigh risk\u201d for every patient, and it is not a diagnosis. Your obstetric provider will assess the complete medical and pregnancy history rather than relying on the use of donor eggs alone.<\/p>\n

Some patients may be referred to a maternal-fetal medicine specialist before pregnancy or early in pregnancy. Others may receive routine obstetric care with additional blood-pressure monitoring, laboratory testing, fetal-growth scans, or other surveillance based on their individual risk profile.<\/p>\n
