New Hope for Mosaic Embryos: CT Mother Gives Birth to Healthy Twins

A local woman has given birth to two healthy baby girls – one conceived using an embryo with some abnormal cells, or a "mosaic" embryo.

A local woman has given birth to two healthy baby girls – one conceived using an embryo with some abnormal cells, or a “mosaic” embryo. After enduring 20 months of IVF treatment, Connecticut mother MaryJo Dunn had just two embryos left. Dunn sought the help of Dr. Lawrence Engmann, a lead physician at The Center for Advanced Reproductive Services (CARS) in Farmington, and eventually decided to proceed.

Dr. Engmann initially recommended against implanting the embryos due to his clinic’s policy. Use of mosaic embryos may result in miscarriage, however there is no current evidence that indicates that there is an increased risk of birth defects. Until recently, embryos genetically tested in a lab were classified as normal or abnormal. Mosaic embryos exist in somewhat of a grey area. According to Santiago Munne, former chief scientific officer of a genetic-testing lab in New Jersey, “they are in-between and they have some potential.”

Riley and Kelsey Dunn were born on December 15 and went home with their family on Christmas Day. ‘The girls have given us so much joy and reason to want to keep going,’ says Dunn. If you have questions about this story, speak with your Ob/Gyn or Reproductive Endocrinologist to see if pregnancy using your mosaic embryos is a viable option. Read more here.

CARS is a close affiliate of Women’s Health Connecticut, with many of our providers referring patients there for fertility services.
