ABSTRACTIn the last decades the function of placenta has remained as a relative mystery considering the current scientific advances, thus their action and the interrelation between the uterus and fetus are not known with detail. In the last years circumstances have been described that felt unlikely inside their functional physiopathology when observing it from the point of view of molecular medicine. Among the recent discoveries it has been described the presence of a specific microbiota, the expression of inflammation molecules, as well as interleukins that act like signs that allow the implantation and functional development in the pregnancy. For that, in many cases of abortion and childbirths preterm it is not possible to establish their causation and are classified as of unknown etiology, resulting in the necessity to find good and new predictors of the the early loss of gestation. It is necessary to stiller understand since the biology of the pregnancy that is the key of the health of the following generations, because during the development of the embryo the illnesses that will manifest in the mature life and that currently have become a problem of public health are generated. Taking into account these new observations, an analysis of the relationship is made, that keep the clinical and molecular aspects in the process of development of the first weeks of the embryo.
