Postcopulatory is a term used in biology to describe events or phenomena that occur after copulation, the act of sexual intercourse. This encompasses a range of behaviors and physiological changes in both males and females of a species. In many species, postcopulatory guarding, where the male remains with the female after mating to prevent other males from mating with her, is observed. This behavior can increase the male's reproductive success by ensuring his sperm is the one that fertilizes the female's eggs.

Another significant aspect of postcopulatory biology is sperm competition. When a female mates with multiple males, the sperm from different males compete within the female's reproductive tract to fertilize her eggs. This competition can lead to the evolution of various male adaptations, such as increased sperm count, sperm morphology that aids in fertilization, or the production of seminal fluids that can harm or incapacitate the sperm of rivals.

In females, postcopulatory responses can include physiological changes related to sperm storage, nutrient allocation to eggs, and even behavioral modifications to influence paternity or the success of fertilization. The study of postcopulatory mechanisms is crucial for understanding sexual selection, reproductive strategies, and the evolutionary dynamics of mating systems across the animal kingdom. It highlights the complex interplay of adaptations that occur in the period following the act of mating.
