Slides of the suspension stained with 1% eosin Y were prepared and dried in room air. Then the slides were fixed with 96% ethanol and stained with the Papanicolaou method.

Sperm with unstructured or dual heads, combined bodies and dual, segmented or angled tails were considered abnormal (Momeni & Daneshpajoh, 2012).
