abstract:Prenatal development is the process in which an immature individual develops before birth. For instance, mammalian prenatal development is the process where an embryo or fetus (or foetus) gestates during pregnancy, from fertilization until birth.
While a study is currently in progress at this point in time with the same research group linked below, specific to those with autism spectrum disorders, the linked research suggests that language development delays in the general population are associated with high levels of prenatal testosterone among males but high levels of prenatal testosterone among females provides a protective effect for language development.
