This piece questions a recent study on reducing teen pregnancy, but I found the introduction to be the most interesting part:

One of the more extraordinary experiences of my medical career was injecting rural African women with a long-term contraceptive in a Catholic mission hospital under a portrait of Pope Paul VI. The contraceptive was handed to me by an aged Swiss nun who was otherwise deeply orthodox, but who recognized that worn-out women who had already had ten children were in danger of their lives if they had any more. I refrained from remarking on the paradox: I had already learned that there is more to life than intellectual consistency.
