Okay. So maybe everyone isn't infertile.

As a follow-up to this post, not everyone who has to do IVF is infertile.  My eyes were opened a little after chatting with the contracts manager with whom I work closely.  I basically blurted out that my son is an IVF baby.  That opened the door for him to tell me his story.  As it turns out, he and his wife are NOT infertile.  They are choosing to do IVF so that they can genetically screen embryos and only choose those that are not positive for a dominant gene that causes retinoblastoma (cancer of the retina).  The contract manager's wife had retinoblastoma as a young child (as did her own mother) and both she and her mother lost an eye to this disease.  They are choosing to do IVF because the only other way to guarantee that they don't have a child with retinoblastoma is to get pregnant naturally, do CVS or amniocentesis testing and then abort if the child does have the dominant gene.  I don't know many who would be able to go through that.  But on their first IVF, they had bad luck.  Out of 7 embryos tested, six had the cancer gene and she did not get pregnant with the one good embryo.  (As it turns out, she never miscarried.  She just was super duper upset that she didn't get pregnant with the good embryo).  They just finished their second IVF cycle and are waiting to hear back on the genetic testing.  I'm really hoping that their luck turns and that they are successful with this cycle.
