As your repeated sperm counts are shoeing azoospermia
that is no sperms, you need to get some hormone tests done, like FSH. This will guide to the possible cause of azoospermia, whether some obstruction to the passage or some testicular cause.
May have to do testicular biopsy
Hope to have cleared your doubts.
