Alcohol exposure can result in fetal alcohol spectrum disorder: condition resulting from high levels of prenatal alcohol exposure, causing learning disabilities, physical growth, retardation, facial malformation and behavioural disorder: genetic disruptions of fetal development. Genetic disorders or random errors in cell division are a second adverse influence on prenatal development. Can result in an impaired development of organs or organ systems: prematurity. Premature infants are born at fewer than 36 weeks. The viability point, the point in pregnancy at which infants can typically survive on their own is around 25 weeks. They often experience serious delays in cognitive and physical development. With each week of pregnancy, the odds of fetal survival increase and the odds of developmental disorders decrease.
