The womb is the first developmental environment. After developmental psychobiologists started to investigate intrauterine evolution of infant and its long-term impact, they found that prenatal and postnatal development is influenced by mother’s psychological health. Specifically, scientific research evidence indicates that prenatal stress is a possible cause of subsequent psychopathological vulnerability. This vulnerability comes from stress sensitivity and is the basis of many childhood disorders. In the last decade, there are evidences for a fetal origin of stress sensitivity in the context of the fetal programming theory (Entringer et al., 2009, Grant et al., 2009, Gutteling et al., 2004, Huizink et al., 2004, O’Connor et al., 2005). According to fetal programming hypothesis, babies that have been exposed to high levels of prenatal stress would develop elevated HPA axis reactivity and thus increased stress sensitivity in the postnatal period. In the field of animal psychobiology, several studies have shown that prenatal stress could play some role on fetal programming of neurodevelopment and HPA axis (Glover, 2010, Weinstock, 2005, 2008). In human psychobiology, evidences are less clear (Glover, 2010). Although research in this regard has been growing during the last few years, more studies are warranted to investigate the relationship between maternal stress and fetal programming of neurodevelopment and the HPA axis in humans, to confirm the findings which are evident from animal psychobiology...
