wow, I should have thought a little bit more before I asked the question This is still something I would like to work into my paper tho, so thx for your help fellas

Hey everyone, I'm currently working on a college paper and I need to know what the percentage is of zygotes that fail to attach to the uterus, and are naturally aborted. I've been looking around the web and most things have said around 65%-70% which my gut tells me is a little high. Also one place said 18%. If anyone knows the correct percentage please let me know. Also if you could, it would be helpful if you linked me to a credible site that has this information and that I can site on my paper. Thanks in advance
