A new study published in Reproductive Sciences describes the mechanism that keeps these conflicting goals in balance. The placenta tricks the mother by creating a diversion to occupy her lymphocytes, allowing invasive trophoblasts to sneak into her arteries and increase blood flow to the placenta.
A new Stanford University study found that the overall quality of a pregnant woman's diet is linked to a lower risk of two types of serious birth defects. Women who ate better before and during pregnancy had fewer infants with brain and spinal cord malformations or orofacial clefts, such as cleft lip and palate.
A team of scientists has discovered a link between pregnancy protein and Alzheimer's disease, finding elevated levels in women destined for the condition years before symptoms appear. They found that the protein, pregnancy zone protein, is being produced in senile plaques, a hallmark of AD.

Researchers found that smoking during pregnancy is associated with lower levels of high-density lipoprotein (HDL) cholesterol in children. The study suggests that this could predispose them to a higher risk of cardiovascular disease later in life. Children born to mothers who smoked during pregnancy had lower HDL cholesterol levels, wh...
A new study published in Acta Obstetricia et Gynecologica Scandinavica reveals that inducing labor around term does not associate with higher rates of cesarean sections. The research analyzed data from the Danish Birth Registry and found no increased risk for cesarean section among induced women compared to those who waited longer.
