Spermiogenesis of Smeringopina bineti. TEM. AÂ Early to mid-spermatid, cross-section. The chromatin condensation becomes filiform. BÂ Mid spermatid, cross-section. Note the fibrillar chromatin condensation and the presence of microtubuli in the IF. C Late spermatid, cross-section. The microtubules in the IF begin to disintegrate. The NC is situated in a fine extension along the prcN. DÂ Coiled spermatid in the lumen of the testis. The IF begins to fill with glycogen. The NC in its extension is folded towards the nucleus
