Sperm competition: linking form to function

  title={Sperm competition: linking form to function},
  author={Stuart Humphries and Jonathan P. Evans and Leigh W Simmons},
  booktitle={BMC Evolutionary Biology},
Using information from physics, biomechanics and evolutionary biology, we explore the implications of physical constraints on sperm performance, and review empirical evidence for links between sperm length and sperm competition (where two or more males compete to fertilise a female's eggs). A common theme in the literature on sperm competition is that selection for increased sperm performance in polyandrous species will favour the evolution of longer, and therefore faster swimming, sperm.
