What is the term for the period during which a female is fertile and her ova can be fertilized?

The term that appropriately describes the period during which a female is fertile and her ova can be fertilized is known as estrus. This phase is characterized by the readiness of the female to mate and typically corresponds with ovulation, which is when an ovum is released from the ovary. During estrus, there are significant behavioral and physiological changes in the female, signaling her readiness for reproduction and her highest chances of conception.

Ovulation itself is the specific event when an ovum is actually released, but it does not encompass the entire period of fertility. Menstruation refers to the shedding of the uterine lining and is not related to fertility in the same way. Mating season describes a broader timeframe in which many species breed but does not pinpoint the specific fertile period for an individual female. Thus, estrus specifically defines the crucial fertile window during which conception is most likely to occur.
