I see where the confusion comes from. It's actually a punctuation error. It should read "Republican lawmakers are drafting new legislation that will make
marriage a requirement for motherhood in the state of Indiana,
including specific criminal penalties*,* for unmarried women who do
become pregnant 'by means other than sexual intercourse.'"

Another article (http://newstandardnews.net/content/?...em&itemid=2445), states it more clearly: "The proposed legislation would bar unmarried people from having babies except through sexual intercourse and makes doing so – or even attempting to do so – a misdemeanor."
