First Use Of DNA Fingerprinting To Identify Viable Embryos

Fertility researchers have used DNA fingerprinting for the first time to identify which embryos have implanted after in vitro fertilization and developed successfully to result in the births of healthy babies. The technique, combined with sampling cells from blastocysts before implantation in the womb, opens the way to pin-pointing a handful of genes that could be used to identify those blastocysts most likely to result in a successful pregnancy.
