PATHOLOGY

Detailed explanation-1: -THE SPERMATOZOON CONTAINS approximately 50–75 pieces of mitochondria in its midpiece. The structure and function of the sperm mitochondria are essentially similar to mitochondria in somatic cells. The sperm mitochondria produce energy for the movement of the sperm.

Detailed explanation-2: -However, the most valuable aspect of mitochondria function in all types of cells is the production of chemical energy in the form of ATP which can be used, in the case of spermatozoa, for sustaining sperm motility.

Detailed explanation-3: -The principal piece of the sperm tail is devoid of mitochondria and enriched in glycolytic enzymes (Eddy et al., 2003; Krisfalusi et al., 2006), many of which are distinct from the isoenzymes present in somatic cells (Welch et al., 1992, 2000, 2006; Bunch et al., 1998; Vemuganti et al., 2007).
