[b](PhysOrg.com) -- A healthy baby has been born from an embryo that was kept frozen for nearly 20 years, smashing the previous record of 13 years. The new baby is a biological sibling of a child born to the embryo donor couple about 20 years ago.[/b]

The baby’s unnamed mother, 42, is from the US and had been undergoing IVF for 10 years without success. Then last year an embryo that had been kept frozen for almost 20 years was thawed out and implanted into her uterus. The baby boy was born in May and weighed 6 lb 15 oz (about 3 kg). The embryo, along with four others, was created as a result of IVF treatment that resulted in one of the embryos being successfully implanted in the mother and brought to full term. The remaining embryos were then donated anonymously for “adoption” by other couples, and frozen.
The four pronuclear stage embryos were offered to the woman and thawed out but only two survived the process. Two embryos were implanted into the recipient, but of these only one survived to full term. (Pronuclear stage embryos are just-fertilized eggs in which the chromosomes derived from the father and mother have not yet fused and the cell has not yet divided.)
The woman's doctor, Director of the Jones Institute for Reproductive Medicine at the Eastern Virginia medical school, Dr. Sergio Oehninger, said the patient had been receiving fertility treatment unsuccessfully for many years, but her persistence had now paid off.
Dr. Oehninger’s research showed that keeping the embryos frozen for a long time does not affect their viability, and it may be possible for them to remain viable 40 years or more, although Oehninger said it would be unlikely such an old embryo would be used as this would mean a new generation using embryos of a previous generation. This issue has already been raised with a mother in 2007 freezing some of her own eggs for the use of her daughter (then 7), who has a medical problem that will probably leave her infertile. If she uses the eggs, her child would also be her own half-sister or brother.
The previous record for a frozen embryo being implanted and brought to full term was set in 2005 by San Francisco mother Debbie Beasley, who was then aged 45. The embryo, which resulted in the birth of Laina, had been frozen for 13 years. In 2009 a baby girl was born after IVF using sperm that had been frozen and stored for 22 years.
Freezing embryos by suspending them in liquid nitrogen is a common procedure in fertility clinics, but the length of time frozen embryos can be stored varies from country to country. As well as embryos, eggs, sperm, and ovarian tissue can also be frozen to allow for multiple attempts at becoming pregnant without repeatedly having to give samples or create embryos.

:science:
wait what the fuck
so they took a 20-year-old frozen embryo(i'm tempted to think of it as a fetus) and implanted it into a uterus
and it fucking developed?
so that baby is 20 years old?
Wonder what it feels like to be a science experiment.

I'd brag about it.

I wish I was born like this :saddowns:

That post goes great with the fact that your avatar is from Metal Gear Solid.
I'm willing to bet the baby'll have at least one if not more health problems due to this.

of course it will, everyone gets sick at one point in time.
Little bastard can drive a car.
He's also a registered voter.
Snap, now I feel old, that baby looks so much younger and healthier and he's the same age.
How did they even unfreeze it properly? Don't cells burst when you freeze them?
If they can do it with a fragile embryo then why not a whole person.

I'm sure embryos are more stable than any other cells.

No they took a single cell, the embryo, inseminated it in a test tube after it thawed, and implanted the now active zygote into the womb in hopes it would attach to the womb lining and LIVE!!! :science:
It's that simple.

Only if ice crystals form inside the cells, dehydrate it and you should be okay.

If I were him I wouldn't complain about it. The development of your personality, and probably 'you' (as a conscious entity) is no doubt something that can only happen given that things go EXACTLY PERFECTLY. 'He' wouldn't ever have existed if he WASN'T a science experiment.

Killjoy.
O, Brave New World!
somehow i thought 20 years was a long time and we were going to have a neanderthal walking around sometime
i don't know how

His older brother is the same age as him
