Reply to comment by jimihughes in Cooperative sperm outrun loners in the mating race. In simulated reproductive tracts of animals like cattle and humans, the behavior increases the chances that groups of cooperative bovine sperm will outpace meandering loners as they race to fertilize a female egg cell, physicists report. by MistWeaver80

They dont cooperate though. they literally ride other spermatozoids to save energy for their own run. If you call spermatozoids being programmed then they are programmed to benefit from the toil of others.
