as to the large number of sperm required, it is note worthy that excess male germ cell's is the norm for many?, most?, all?, species, and that in a lot of cases there is a number of complications involved in transfering them to a female, and altogether improbable solutions, also the basic mechanisms for germ cells are conserved by plants and animals, "pollen" bieng tailess sperm.....except in the case of ginko trees, that have motile sperm so the real questions are around why did evolution produce, and stick to this mechanism, and not so much about our species rather mundane take on it.
