i've had a hysteroscopy a coulple of years back, and that part was pretty straight forward - dialate the cervix and send a fibre optic camera in for a squzzy. the biopsy is probably to check for the presence of NK (natural killer) cells - i didn't have this done, but i know a lot of ladies have had this done - i believe there is a thread about immunological tests that is a sticky in either LTAC or LTTTC - might be worth you having a bit of a read up hun

hope it all goes smoothly for you
