EVMS Jones Institute for Reproductive Medicine continues to lead the infertility field with medical breakthroughs that pave the way for thousands of women to have children in middle age.

A 42-year-old patient of Dr. Sergio Oehninger became a mother after being implanted with an embryo that was frozen 20 years ago ? The longest time a fertilized egg has been stored before developing into a healthy baby. The newborn?s mother had undergone 10 years of IVF but was unable to conceive. Last year, a frozen embryo, created by another couple, was implanted into her womb and in May she gave birth to a healthy boy weighing 6lb 15oz.

The embryo was created with four other when the couple were having a successful IVF treatment in 1990. When one was successfully implanted, they donated the other four for ?adoption? and these were frozen.

Two decades later, the four embryos were offered to the 42-year-old woman and her husband after being selected from a list that offered the best physical match. The couple was informed about the amount of time these embryos were in storage. Only two embryos survived the thawing process and they were implanted in the woman?s womb. One survived, and the pregnancy went full term.

Dr. Oehninger has carried out research showing that the length of time embryos are frozen does not hinder their ability to grow into healthy babies.

Some doctors believe frozen embryos could be stored for as long as 40 years. Previously, healthy babies had been born from embryos frozen for 13 years.
