Spermatids are recognizable not only by their smaller size but also by their dark, condensed chromatin and juxtaluminal position within the tubule.
Sertoli cells observed in some of the tubules were vacuolated preformed spermatids.
Since the distal centriole gave rise to the sperm axoneme during spermiogenesis, it is logical to suppose that the proximal centriole that is inherited by the embryo could cause aberrant mitosis as both are derived from the same mother centriole in spermatids.
Increase in percentage of abnormal seminiferous tubules along with the decline in number of spermatogonia, primary spermatocytes, secondary spermatocytes and spermatids probably correspond to the decrease in testosterone production or inhibition of pituitary gonadotropin secretion, which resulted in disruption of spermatogenesis (Raji and Bolarinwa, 1997).
