sperm competition
Mating contest within
Sperm competition is the biological phenomenon where sperm from multiple males compete to fertilize a female's eggs.
The term appears in evolutionary biology and animal behavior studies to explain traits like large testes, copious ejaculate, or mate-guarding behaviors: Sperm competition has shaped mating strategies across species.
The concept extends to humans in discussions of sexual selection and reproductive biology.
