Among the exogenous factors, we expect maternal nutrition, maternal chronic diseases, About Darwin Smith embryonic or fetal infection, and toxic effects in the mother as well as the optimal function of the placenta (Table 1). Hormonal influences was until recently attributed to only a marginal impact.
