It seems like a science fiction story or a fantasy born of who knows what visionary mind, yet it is all true – a Tennessee born girl can claim to be the “biggest” baby ever born, thanks to the embryo cryopreservation technique.
the embryo freezing It is a practice that has been used for a long time in medicine: in assisted reproduction cycles, although it is limited to the minimum, it is sometimes necessary to freeze the embryos of a couple for future attempts. Even donated or unwanted embryos can be frozen, maintaining the total anonymity of the donor.
Over the years there has been a lot of debate about the effective effectiveness of this practice, especially when analyzing the possible risks to embryos when frozen and then thawed. The temperatures we are talking about are incredibly low, backed by the help of liquid nitrogen. around -237.78 ° C.
Modern research has made great strides and has greatly reduced the risk of losing samples. It is precisely in this sense that we are going to insert the news that we are about to tell you: one of these embryos has been frozen in cryopreservation for nearly twenty-eight years, setting an absolute record, before being “transformed” into a full human.
Of that embryo was born on October 26 late Molly Everette Gibson. His adoptive mother, Tina Gibson, is now 29 years old and this allows us to affirm that the two women are almost the same “biological age”.
“Is hard to understand“- he said Tina gibson – “But as far as we’re concerned, Molly is our little miracle“The story is even more fascinating because the adoptive couple has always struggled with infertility problems, and already in 2017 had been the protagonist of a” cryogenic “adoption that gave birth his first daughter, Emma. The latter shares the same genetic inheritance as the most recent, since they were two embryos donated to the “National Embryo Donation Center” (NEDC) by the same anonymous mother.
Two real sisters they find themselves united in a loving new family after nearly thirty years of freezing.
NEDC, a Knoxville-based organization, receives embryos from biological parents who have tried IVF but, for one reason or another, did not want to continue the pregnancy. In these cases, instead of letting the embryos be lost, parents can donate their embryos and have them frozen, in order to save for later use for those who want to be parents sooner or later.
A story that shows us how much science and medicine are striving beyond the most optimistic expectations. And, in this sense, Cryopreservation is likely to keep samples in optimal condition even after 50 years.. If this is true, time will tell.
Continuing with the topic of fertility, did you know how powerful the hardware of a pregnancy test is? It has also recently been discovered that the use of certain contraceptives can cause some infertility problems.
