Immotile (IM);

Non- progressive (NP);

progressive (PR);

Anilline blue positive cells (AB+): Sperm heads with more intense reaction showed immature sperms with more histone content;

Chromycine A3 positive cells (CMA3+): Sperm heads with yellow florescence reaction showed protamination deficiency.
