Baby Steps: Fertility Findings on CCS
With in vitro fertilization, a new procedure known as CCS screens embryos for chromosome problems before they're transferred to the patient, allowing doctors to implant only healthy embryos. "We can get pregnancy rates similar to younger women when we transfer these normal embryos back," said William Schoolcraft, M.D., founder and medical director of the Colorado Center for Reproductive Medicine, explained. With CCS, women 35 to 37 have a 78% chance of pregnancy. Those 38 to 40 have a 68% chance and women up to 42 have a 62% chance. Another technique known as vitrification is making IVF more effective when embryos have to be frozen.
