hi! welcome to bb. im sorry to hear your embryos arent sticking =( i dont have any advice because ive never had a lap or endo. my dh and i did do icsi to get our daughter and wil have to for any future babies but like you it is completely because of male factor. we did use 5 embryos just to get our DD.
will be thinking about you next week and really hope your next FET is a sticky sticky thing.
