The centriole (c) lies posterior to the nucleus, and the axoneme (ax) emerges from it.
These mitochondrial abnormalities were mostly accompanied by defects in the structure of axoneme, in the form of missing peripheral microtubules or, more commonly, missing central microtubules.
The axoneme possesses the 9 X 2 + 3 pattern of microtubules (Fig.
Electron microscopy led to the discovery of the 9-plus-2 arrangement of internal fibrils in the cilia and the subsidiary components of the axoneme, which lent support to the "sliding fibril" hypothesis of ciliary bending.

62,63) Finally, the mitochondria are arranged in a helix of 11-13 gyri, with two mitochondria per gyrus, and deliver ATP to the axoneme for flagellar propulsion.
In general, flagella and cilia of eukaryotes show an axoneme composed of a 9 + 2 microtubular pattern.
ROS increases DNA fragmentations (32), modifies the cytoskeleton (21), affects the sperm axoneme development (13), and inhibits sperm-oocyte fusion (2).
The proximal centriole remains associated with the dense fibers of the flagellum and the distal forms the axoneme.
The axoneme is surrounded by 9 bundles of peri-condensed fiber that parallel the axoneme, forming the "9+9+2" arrangement.
