* Folicular waves generally occur every 10-12 days, but there is variation between individual animals.
* Folicular waves generally occur every 10-12 days, but there is variation between individual animals.
* As [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicles]] mature, they produce Oestrogen, which is responsible for receptivity behaviour.
* As [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicles]] mature, they produce Oestrogen, which is responsible for receptivity behaviour.
* Once [[The_Ovary_-_Ovulation_-_Anatomy_%26_Physiology|ovulation]] has occured,luteinization occurs with the formation of a corpus luteum.
* Once [[The_Ovary_-_Ovulation_-_Anatomy_%26_Physiology|ovulation]] has occured,luteinization occurs with the formation of a [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|corpus luteum]].
* Corpus luteum produces progesterone.
* [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|Corpus luteum]] produces progesterone.
* Progesterone inhibits further [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicular development]] and triggers rejection behaviour.
* Progesterone inhibits further [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicular development]] and triggers rejection behaviour.
* If there is no pregnancy, luteolysis occurs and the corpus luteum is broken down. This allows a new [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicle]] to develop.
* If there is no pregnancy, luteolysis occurs and the [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|corpus luteum]] is broken down. This allows a new [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicle]] to develop.
* The overlapping nature of follicular waves and the fact that the female is receptive even if the [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicle]] is not mature enough to [[The_Ovary_-_Ovulation_-_Anatomy_%26_Physiology|ovulate]] makes it difficult to determine from behaviour when the optimum time for mating is.
