The estrous cycle is the correct phase of reproduction that indicates when a female animal is particularly receptive to mating. During this cycle, specific hormonal changes occur, leading to a heightened state of receptivity known as "estrus" or heat. During estrus, physiological changes take place that signal to males that the female is ready to conceive. This includes behavioral changes such as increased vocalization, restlessness, and specific body language that indicates readiness for mating.

In comparison, pregnancy refers to the period when the female is carrying developing offspring and is generally not receptive to mating due to hormonal changes that maintain the pregnancy. Lactation, on the other hand, is when the female is nursing her young, and while it is a critical period for nurturing her offspring, it does not correspond to receptivity for mating. The youth period describes a stage in an animal's life cycle during which it is developing and growing, but it is not specifically linked to mating behavior or receptiveness. Thus, the estrous cycle is the distinct phase that directly correlates with mating receptivity in female animals.
