A baby girl born in Britain is a record breaker as she is the longest frozen embryo to result in a live birth after 11 years, 2 months and 5 days.
The embryo had been preserved for more than a decade at the Midland Fertility Services (MFS) in Aldridge, where baby Ryleigh's parents, Lisa and Adrian Sheperd underwent in vitro fertilization (IVF) after Lisa had been diagnosed with endometriosis and polycystic ovaries. Previously the couple had twin daughters in August 1999 after a successful course of IVF and had opted to preserve the remaining 12 fertilized embryos in liquid nitrogen at -196 degree centigrade for a future pregnancy. Generally embryos are retained for 10 years. Every year the couple received a letter from MFS reminding them about the 12 embryos kept in storage. As the 10 years duration was about to end the family had to make a decision on their future and Lisa and Adrian decided to try for another baby.
Lisa said, "When Ryleigh arrived, she looked like both the girls did when they were born 11 years before. It was uncanny. The girls are thrilled to have a sister, and they know that she was conceived at the same time that they were but has been in the freezer."
