This study was done on twenty cases of males divided into two groups: the first group was fifteen cases of subfertile males and the second group was five cases of fertile males as a control.
sample was examined by light and transmission electron microscopy. The light microscopic findings were in the form of head abnormalities and abnormal tail with marked curled formation: The ultrastructural changes revealed abnormalities in the head in the form of acrosomal changes. Also, there were nuclear changes in the form of chromatinic condensation with nuclear vacoulatibn. There was constriction of the neck. The middle piece showed disorganization and disarrangement of mitochondrial structure. Also, the principal piece showed abnormalities in the form of absence of fibrous sheath, reduction or supernumerary of peripheral microtubules and absent central microtubules
