At Oregon Reproductive Medicine, the majority of our IVF patients choose to undergo comprehensive chromosome screening (CCS) on their embryos as part of their IVF cycle.

ORM Genomics Director, Emily Mounts, co-authored a peer-reviewed paper on this challenging topic, which was published in Reproductive BioMedicine Online.
