Great headline on a Catholic World News report citing a German study linking religiosity and the number of children:
“Women of faith found more fertile”
Think of all the money you could save on IVF, huh? Well, actually, CWNews is right that the study is a no-brainer: religious observance does correlate to larger families. But I’m not sure it proves prayer is the secret to fertility.

Berlin, Apr. 24, 2008 (CWNews.com) – A demographic study by Germany’s Max Planck Institute has found a high correlation between women’s religious attitudes and the number of children they bear, the KNA news agency reports.
The Max Planck Institute study, which involved research in 18 different countries, found that women who identify themselves are religious are far more likely than their non-religious counterparts to bear two or more children.
