The dynamics of sperm cooperation in a competitive environment . . . . the group moves with more persistent linearity but without increasing speed . This benefit, however, is offset in larger aggregates as the geometry of the group forces sperm to swim against one another .

Sperm from a wild mouse band together and swim faster than individual sperm . Perhaps the first example of mammalian sperm cooperation, the finding may cause scientists to look for coordination . . .
Sperm cooperation has evolved in a variety of taxa and is often considered a response to sperm competition, yet the benefit of this form of collective movement remains unclear . Here, we use fine-scale imaging and a minimal mathematical model to study sperm aggregation in the rodent genus Peromyscus .

Cooperation confers a competitive advantage by several means, some of these include incapacitation of other competing sperm and aggregation of genetically similar spermatozoa into structures that promote effective navigation of the female reproductive tract and hence improve fertilization ability .

A number of studies have suggested that sperm swimming velocity may be negatively correlated with male social status in some species (Froman et al ., 2002; Rudolfsen et al ., 2006), suggesting that subordinates compensate for their lower status by preferentially investing in the competitiveness of their ejaculates .

Sperm can increase their swimming velocity and gain a competitive advantage over sperm from another male by forming cooperative groups, such that selection should favour cooperation of the most . . .
