There are other forms of sperm competition than sheer numbers. In promiscuous fruit flies, males have evolved sperm that contain toxins that kill that of other males, often to the detriment of the mother’s health and life expectancy (sperm with frickin’ laser beams on their heads).  Closer to home, humans also seem to genetically resemble chimpanzees and bonobos for semen coagulation or ‘mating plugs,’ which could slow any subsequent male’s sperm from traveling through the female reproductive tract (see Eric M. Johnson’s post on this). Finally, as Ryan and Jethá discuss, the shape of the human penis, in particular its rather large size – compared to other primates – and the mushroom shaped glans, makes it particularly effective at displacing semen left by other males from the vaginal tract. Yes, people have tested this (via Jesse Bering). All for science. You should see what they do with ducks. Unbelievable. (Ed Yong). [...] [...] 2.
