Study examines live birth rates following IVF

Thirty years ago last summer, the world's first "test-tube" baby was born, and since then more than 1 million infants have been successfully conceived through in vitro fertilization (IVF), the technique in which a woman's eggs and man's sperm are fertilized in a laboratory and then implanted in the mother's womb.
