A baby boy was born in Ohio from an embryo frozen for over 30 years. This is believed to be the longest time an embryo has been stored before birth. The embryo was kept frozen since the early 1990s.
Dr. Emily Foster, a fertility expert, said, “This case shows that embryos can remain viable for decades with proper freezing techniques.”
