Can IVF Treatments Reverse a Woman's Biological Clock?

Modern reproductive technologies can give older women the same chances of having a baby as younger women, researchers reported Wednesday. The new study found that women age 31 and younger have about a 60 percent to 75 percent chance of having a baby after three IVF cycles.

That essentially gives them the same chances they would have had in their 20s.
