He won't mention it unless you ask. K.ate his nurse told me he doesn't really have an opinion either way.... but he is the type of FS who will do almost anything you ask him to do if he thinks it won't cause you or your cycle any harm and it will make you happy. I don't know if I will use it again as it is a bit of extra cost but I wanted to try it and those were my 10th and 11th embryos (I did a double) so for me it felt good like I was at least doing something different/new. I have done the scratch twice, the pineapple cores, the Bondi protocol, Brazil nuts, advocado lol you name it if it has gotten anyone else a BFP then I too have swallowed it, inserted it, sniffed it. I think I might lean more towards using the embryoscope for the same $$$ instead if it has space.
