A practical consequence of the specific pig reproductive cycle is that the main functional features that distinguish boar spermatozoa cannot be extrapolated to other species. This prevents an overall picture that explains mammalian sperm function from being assumed. Furthermore, the extraordinary complexity of the molecular mechanisms implied in the control and modulation of mature boar sperm functions makes it impossible to provide a complete description of these mechanisms in the limited space of this chapter. Taking this into account, this chapter centers on the description of three highly important specific aspects of boar sperm function. The first aspect is the mechanisms by which boar sperm cells uptake extracellular energy sources. The second aspect is the necessity of mammalian sperm to use other hexoses than glucose as feasible energy sources. The third aspect would be an analysis of the roles that mitochondria could play in the regulation of the overall boar sperm function. As a whole, this revision intends to be an overall picture of regulatory mechanisms involved in the maintenance of proper energy levels of boar sperm and their relationship with the control of the overall boar sperm function.
