let me show you some numbers really quick. first of all, inducing labor means a woman is around her due date she has not yet developed contractions, you give medicines to start those contractions. augments means the contractions have started, but you're going to make the contractions even stronger. take a look at the numbers there, if someone induces, it's about an 18% increase in the likelihood of having a boy with autism. slightly lower if just augmenting, 15%. if you do both, 35% increase overall, and likely to have a boy with autism. >> how common is augmenting or inducing? >> i looked this up as well. i thought it was going to be much more common than i found. overall, inducing labor is about 23%, about a quarter of women have their labor induced. and those numbers are from 2008, the last time it was really recorded, my guess is, it's a little higher now. it's a little lower than most people expected, it's not all women. >> as you mentioned, the findings were much more pronounced among boys, do you know why there's a gender gap? >> i don't know why there is, this could be one of those
