August 11, 2009—Your mother on estrogen in advance of implantation next week. Benefit to using IVF to conceive is you know when it happens. Downside (or one of several downsides), the amount of hormones your mother has to inject into herself. Second implantation this year.
We used, and will use, fertilized eggs from when we conceived your brother. Can’t believe we did that in January 2007. He is almost two. These eggs have been in cold storage.
Our first implantation this year—March? April?—didn’t take. Nothing wrong with the embryo, or with your mother’s body, but IVF is not magic. The science of sperm meeting egg is one thing; the internal multiplication and division inherent in conception is not so defined.
