If you are in support of in vitro fertilization, then you have to recognize that human embryos are being created in excess of what can be used safely to reimplant for a pregnancy. So they're going to end up being discarded.

Each year thousands of embryos, no bigger than the head of a pin, are created in the process of in vitro fertilization, with the support of Congress, by the way.

We expect in two or three months to do an ultrasound to check the embryos and eggs development. After fertilization we are talking a year for pups to be born and with seven gills there could be 60 or more pups.

If you are looking for a needle in a haystack, and somebody has already cataloged all the straw in the haystack, when you get to that needle you will recognize it's different than what was supposed to be there based on all that computerized haystack information that had been predetermined for you.
