Hi Buliej

I don't know if it is illegal to transfer lots of embryo's, I know my FS has a standard practice of only transferring 1 embryo if you are under 36 and then 2 if over 36. Even though I am only 35 (but pushing 36) I have requested 2 embryo's be transferred at my FET as it is approx 3 mths between cycles for me, so if the October one doesn't work the next transfer would be Jan/Feb when I turn 36.

I think they are more concerned with not putting back lots of embryo's as if they all work the health risk to you and the babies is so much higher then a singleton, they don't seem to want that many twin pregnancies either due to the higher risks but allow them so that if they do both work in older patients they are more likely not to undergo IVF for subsequent children as they already have 2.

All you can do is ask your FS if they are willing to put back more than 2 but I would be prepared for a "No", but you never know they might let you....
