The management of growth-restricted fetuses requires accurate diagnosis to optimize the timing of delivery. Doppler velocimetry is the only noninvasive method for assessing the fetoplacental hemodynamic status. This review will give a critical overview of the current knowledge on fetal venous blood flow in pregnancies complicated by in-trauterine growth-restricted fetuses. ...

Cyclooxygenase (COX) inhibitors-acetaminophen, ibuprofen and acetylsalicylic acid-have endocrine-disruptive properties in the rainbow trout. In humans, aspirin blocks the androgen response to human chorionic gonadotropin (hCG), and, because hCG-stimulated androgen production in utero is crucial for normal testicular descent, exposure to COX inhibitors at vulnerable times during gestation may impair testicular ...
