A convoy of sperm -- the remnants of an armada that was once a couple of hundred million strong -- sails into view, their long tails thrashing vigorously. Lured by the chemical signal, several hundred of the most energetic swimmers close in on the egg, their narrow tips unleashing...

"I was so excited I couldn't sleep at night," says Cohen. Apparently eggs with a hole in their outer membrane somehow benefit from that hole. Cohen theorizes that embryos that don't implant may be having trouble...

But now a heartwarming situation has come along in which the moral quandaries pale before that most basic of human instincts: the desire of a parent to take on and take away the pain of a child...
