An Ohio couple welcomed a baby boy born from an embryo frozen for over 30 years, setting a world record for longest storage time before birth.

Lindsey and Tim Pierce used donated embryos through “embryo adoption” after struggling with infertility.

The embryos were donated by Linda Archerd, who created them through IVF in 1994 but couldn’t use them after her divorce.

The baby was born from an embryo stored for 11,148 days, surpassing the previous record of 10,905 days. About 1.5 million frozen embryos are currently stored across the US.
