@Malak: In principle that you can do the FNA mapping and then do the mTESE later on here. Smik has done the FNA mapping with Turek in the states. Unfortunately, they didn't find any sperm with the mapping. Her FS here in Oz was against it with a good reason. What if the removed tubules from the mapping are the only ones with sperms in it? So subsequent mTESE won't be a success. I don't think they can do FNA mapping simultaneously with mTESE + IVF. Of course, one can only try. I would have gone down this option first if it is available here in Oz.
Thanks @MissJude and @twoSouls for your reply and a push to ensure me that it all will turn out to be OK.
