Abstract

AbstractOne hundred fifty-seven pregnancies complicated by different degrees of diabetes, toxemia, and hypertension were studied with serial urinary placental estrogen determinations. A simple and fast method for total placental estrogen determination was used. The level of total estrogen excretion was related to Apgar score in cases of class B diabetes, severe toxemia, and also in moderate toxemia when estrogen excretion was falling. Mean estrogen levels did not differ as a function of severity of diabetes. Levels did differ with severity of toxemia; however, only the difference in mean estrogen excretion between mild and severe toxemia was significant. Estrogen excretion was very low in hypertension but was not related to Apgar score. This study concludes that total urinary estrogens constitute only a single parameter necessary in the management of high-risk pregnancies.
