(CBS) - It's a technology that's helped millions of couples have children. Now in-vitro fertilization, or IVF, has reached a new height. Fertility experts say five million children have been born thanks to medical reproductive assistance. The first so-called "test tube baby" was born in 1978. IVF is a procedure where a woman's eggs are fertilized outside her body -- in a laboratory -- and reinserted into the birth mother's uterus. It's not cheap, the national institutes of health estimates IVF can cost between 12 and 17-thousand dollars.

They found the chances of having a baby that was stillborn, or did not survive the first month was 53 percent greater if two embryos were transferred instead of one.
