Some race for the ovum, but some remain behind in the entrance to the fallopian tube and form a rear guard. And if any sperm from another mail come along, they attack. There may even have been an "advance guard" whose job it was to attack the other males' sperm rear-guard and clear the way. The show had footage of one sperm attacking another sperm, and boring into its victim at the point where the tail meets the head. After a few moments, the victim sperm was dead.
