Extremely high estrogen levels may underlie complications of single-birth IVF pregnancies

Researchers have identified what may be a major factor behind the increased risk of two adverse outcomes in pregnancies conceived through IVF. Their findings support the hypothesis that extremely high estrogen levels at the time of embryo transfer increase the risk of infants born small for their gestational age and the risk of preeclampsia. They also outline a protocol that reduced those risks in a small group of patients.
