Alcohol consumption during pregnancy has become a prevalent phenomenon worldwide in general, as well as in Israel in particular. This habit is associated with an increase in various complications during pregnancy - mainly fetal alcohol syndrome and post-natal fetal alcohol spectrum disorder. There is no "safe limit" for alcohol consumption during pregnancy and alcohol drinking may be detrimental to the fetus or to the newborn when consumed at any stage of the pregnancy. The negative effects of alcohol consumption during pregnancy are also related to a shortage of key nutritional elements due to this habit. The main negative results of this habit are fetal alcohol syndrome and fetal alcohol spectrum disorders. Pregnant women after infertility treatment are also not deterred from drinking alcohol. Education of pregnant women is currently regarded as the best treatment.
