The mature spermatozoon consists of head, midpiece and tail.The acrosome is in upsidedown Vshape.The nucleus,which consists of major part of the head, is eggshaped with high density. It contains anterior nuclear fossa, posterior nuclear fossa and implantation fossa; the centriolar complex which is surrounded by 4- 5 ovalshaped mitochondria,forms the midpiece.The flagellum is a typical + 2 microtubular structure.
