Coeliac disease in the father affects the newborn
Wow!! Forever the male has been viewed as rather unimportant in the health of the fetus, and yet several studies are starting to show that this is far from true. In this case, coeliac disease (allergy to gluten proteins most commonly found in wheat), whether treated or untreated has an effect on the birthweight. While I would find it hard to follow a pathway that would lead to a defect in the sperm resulting in this outcome, coeliac disease may be a factor that is transferred to the fetus and has a rapid phenotypic expression in the developing fetus.
