This hour: IVF -- in vitro fertilization -- has brought the miracle of life to women and families across the U.S.

Those who have undergone the procedure, however, know it does not come without a cost.

Coming up, we weigh the physical, financial, and emotional demands of IVF treatment.

We hear from doctors and patients.

We also consider a recent New York magazine article about PGS -- the test used to identify viable embryos. How accurate is it? We take a closer look.
