I was to ask the embryologist: in order to have a successful IUI for gender selection, is it possible to have multiple sperm sample collected (say over the course of a week) and then have the sperm sort (gradient method) done on them a few times i.e. separate first time, then take the layer containing most of the desired sex and separate again one or two times, until you have a final sort sample that hopefully contains majority sperm cells of desired gender?
