I know the statue supposedly solves this but it still doesn't sit well with me. Ethan was born on the island. The problem with the fertility wasn't that women couldn't get pregnant, it was that they would get to the 3rd trimester and the something in the mother's body would "attack" the fetus. I know they said women would go off island to have the babies but it wasn't the delivery that was the problem, as witnessed by Danielle, Claire, Claudia and Amy. It was internal, earlier in the pregnancy. I just feel like they had a nice little mystery going, then called an audible, made the statue a fertility god and changed it to "no babies, ever."
