A baby has been born after becoming the longest-frozen embryo after being cryopreserved for 24 years.
Wait a minute, what are you talking about?
We guess a little explanation is needed, so we’re consulting online health resources to help out.
Embryo: When a virile sperm meets a matured egg during sex or artificial means, fertilisation occurs and a zygote is formed. Scientists say this zygote divides and begins development but is not considered an embryo until it is five weeks old. During this embryonic stage, most of the baby’s system begins to form, so it’s a pretty important and critical stage. At five weeks, the size of the embryo is only about the size of the tip of a pen, can you believe that? Amazing? Furthermore, it is not until the embryo is nine weeks, that it is considered a foetus.

Ok, we got that, what about the other term, cryo…. cryopreservation, yes!
Cryopreservation: It just a way of preserving living tissues using very low controlled temperature. It’s a bit akin to preserving meat in a freezer but it requires more technicality because while your meat is a ‘dead meat’- pardon the pun - cryopreserved materials are alive and you want to not only keep them that way but also ensure their integrity is maintained. By that, we mean their structural and functional characteristics are not damaged in any way. Use this link to know more about it all.
Thanks for that much-needed explanation, now let’s hear the story.
The world’s longest cryopreserved baby has been born and she’s very healthy. She was preserved as an embryo in 1992 and was born this year, 25 years after her fertilisation.
The baby, a girl named Emma Wren Gibson, was born on November 25, 2017, in the US after a medical director, Dr Jeffrey Keenan, of the National Embryo Donation Centre (NEDC) performed a frozen embryo transfer (FET), the Independent reports

Though Emma was delivered this year, she was frozen as an embryo on October 14, 1992.
