* Follicular waves occur, where a follicle will gradually mature to a point when it could be [[The_Ovary_-_Ovulation_-_Anatomy_%26_Physiology|ovulated]] should mating occur.  It will then regress if no mating takes place.

* Folicular waves generally occur every 10-12 days, but there is variation between individual animals.

* As follicles mature, they produce Oestrogen, which is responsible for receptivity behaviour.

* Once 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 corpus luteum.

* Corpus luteum produces progesterone.

* Corpus luteum produces progesterone.

* Progesterone inhibits further follicular development and triggers rejection behaviour.

* If there is no pregnancy, luteolysis occurs and the corpus luteum is broken down.  This allows a new follicle to develop.

* The overlapping nature of follicular waves and the fact that the female is receptive even if the 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.
