I do believe they meant that religion played a big part in spreading the notion, not that we should be listening to it. Word of mouth was obviously another big factor there.Oh Jesus you're saying it should be listened to because it's in a religious text? Mate I'm not touching that with a 10ft pole lest I end up getting banned.
Have fun thinking that way if you like, wouldn't recommend opening up about it to many women though.
However, I'm curious as to how true claims that most women were unprepared/uneducated about sex/pregnancy even so far as antiquity are though...
