For decades, researchers have been debating whether sperm cells get their fuel, molecules of ATP, from mitochondrial oxidative phosphorylation or glycolysis. Their work advances our understanding of the cellular physiology of sperm, which in turn may have some bearing on the development of a male contraceptive pill and better in vitro fertility techniques. The investigators decided to tackle proteomic analyses of the tail of human sperm, because previous studies indicated many sperm metabolism proteins are located there.

The process of fertilization involves a cell fusion event between the sperm and oocyte. Although sperm contain mitochondria when they fuse with the oocyte, paternal mitochondrial genomes do not persist in offspring and, thus, mitochondrial inheritance is maternal in most animals. Recent evidence suggests that paternal mitochondria may be eliminated via autophagy after fertilization.
