This is a photo of the twins I carried, taken shortly before they were transferred to me. They were fertilized in Australia, frozen when they had grown for 5 days, then hand delivered to our clinic in the States. If you look closely at the embryos, you can see a very faint ring around each of them. Those rings are the last little bit of ice left on them as they were thawing. It still blows my mind to think that you can freeze and thaw an embryo, and if all goes well, it will survive the thaw, begin growing again and then be implanted into a stranger’s uterus and grow into a healthy baby. Technology is truly amazing.
