I recently had a embryo transfer. On egg collection, they collected 11 eggs all together. Unfortunately only 2 were good enough to use. The other nine came out with vaccule sacs on them, which they said they have seen before but it's uncommon to get so many with them on. As I'm only young, they advised to have one embryo transferred, which I had done yesterday. Has anyone else had these vaccule sacs found on their eggs?
