The first stages of placental development take place days before the embryo starts to form in human pregnancies. The finding highlights the importance of healthy placental development in pregnancy, ...

One often thinks that the early embryo is fragile and needs support. However, at the earliest stages of development, it has the power to feed the future placenta and instructs the uterus so that it ...

Alcohol exposure in very early pregnancy (before embryo implantation) can lead to long-term molecular changes detectable in the placenta, potentially providing a tool for early detection of prenatal ...

A calf was born from an embryo lacking cells which form a large part of the placenta, providing new insight into the regenerative capacity of mammalian embryos. Mammalian development starts from a ...

A new study led by Pr. Serge McGraw, researcher at CHU Sainte-Justine and professor at Université de Montréal, shows that the effects of alcohol exposure on an embryo prior to implantation in the ...

HONOLULU — The risk for placenta accreta is 3 times higher in pregnancies achieved with in vitro fertilization using frozen embryo transfer than in those using fresh embryos, according to a new study.

Early alcohol exposure reduced blood vessel formation in the placenta, and this led to fewer nutrients being delivered to the embryo. Drinking alcohol even at conception was found to damage placenta ...

Scientists have identified a key process in the very early stages of embryo development that they believe could pave the way for improved fertility treatments and help those struggling to conceive.
