Objective microdeletions of Yq chromosome are the most frequent molecular genetics etiology for the male infertility which usually spans AZFa (azoo spermia factor a), AZFb and AZFc regions. Microdeletions are mostly seen in AZFc region and usually cover genes actively involved in spermatogenesis. Partial AZFc microdeletion may also happen with various spans namely gr/gr, b2/b3 and b1/b3. It is ...
