After egg retrieval comes fertilization. As part of fertilization a number of poor quality embryos are created, and discarded. The doctors we used would only insert “A” or “A-” embryos if memory serves. Also, the number of quality embryos that are created are sometimes greater than a family would want inserted (ignoring that is how we ended up with Octomom a number of years ago). These are the embryos that the Alabama decision seems to prohibit from being destroyed.
