More than five million babies have been born thanks to In vitro fertilization treatments since the world’s first “test tube baby” was born in 1978. This method made motherhood a possibility for women struggling to conceive, by carrying the process of fertilizing a human egg with a sperm cell outside the body, and then placing the fertilized egg back in the womb.
But this method also has some serious problems: success rates are only 20-30 percent; the rate of abortions is high; and it usually takes a series of tries before an IVF treatment succeeds.

The main obstacle doctors face is finding the right sperm cell, as IVF lacks the natural mechanisms in the woman’s body that make sure that only the best sperm will fertilize the egg - but sperm cells not only move very fast, they are also nearly transparent under the microscope. It’s like a cat-and-mouse game on a microscopic scale, and the mouse is invisible.
