A report from the National Birth Defects Prevention Study (1) was recently released. Counter to two previous studies, it found no association between vegetarian diets in pregnant women and having a boy with hypospadias. This makes six studies examining the association to date with four finding no association.

This is great news, but we are not completely out of the woods yet. There is still reason to make sure that pregnant vegans cover all of their bases.

I have revamped the article Hypospadias and Vegetarian Diets on VeganHealth.org where you can read the fine print.
