On the NOVA special "Life's Greatest Miracle" tonight
there was a comment that more than 50% of blastocysts
(embryos?) fail to develop properly.
This was a question that came up a few weeks ago.
I had heard in some class I took at the Univ. of Washington
that the number could be as high as 70%.
No references, sorry.
