I think yes fetility is perhaps better in the 20s (I was lucky to fall in month 1 and 3 with mine when trying, but that's not for all people), however, just like this story shows, there is so much they can do now to help people out in the fertility department, should they need it, so if you don't want or don't happen to have children 'til your 30s or even 40s don't worry about it. It's no one's business but yours
