The swelling and changes in the color of the skin surrounding the female's genital area in Old World monkeys is generally an indication of estrus or the female's readiness to mate. This is a common reproductive behavior in Old World monkeys, which includes baboons, macaques, and mandrills. It is not a sign of aggression or a diseased state. While some New World monkeys also have visible changes in their genital areas during estrus, it is not universal among all species.
