The spermatozoon flagellum is divided into four distinct segments: the connecting, middle, principal, and end pieces, and it is composed of four major structural components: the axoneme that spans the whole length of the flagellum, the outer dense fibers surrounding the axoneme in the middle and principal pieces, the mitochondrial sheath located in the middle piece surrounding the outer dense fibers and axoneme, and the fibrous sheath in the principal piece (Inaba, 2011).
