Sperm Competition

Sperm competition refers to the process by which sperm from different males compete to fertilize the eggs of a female. This occurs when a female mates with multiple males. In such scenarios, sperm must work effectively to outmaneuver and outlast rival sperm. This can lead to various adaptations in males, such as producing more sperm, developing faster swimming abilities, or even employing tactics to remove previous sperm from the female. Sperm competition is a common phenomenon in many species and plays a significant role in reproductive success and evolution.
