* Developing follicles produce '''Oestrogen''' from '''Theca and interstitial cells''' and '''Progesterone''' from '''Granulosa cells'''.
* Developing follicles produce '''Oestrogen''' from '''Theca and interstitial cells''' and '''Progesterone''' from '''Granulosa cells'''.
* Increasing levels of Oestrogen stimulate an '''LH surge''' to cause the [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicle]] to split and release the primary [[The_Ovary_-_Oocytes_-_Anatomy_%26_Physiology|oocyte]].
* Increasing levels of Oestrogen stimulate an '''LH surge''' to cause the [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicle]] to split and release the primary [[The_Ovary_-_Oocytes_-_Anatomy_%26_Physiology|oocyte]].
* '''Oestrogen mobilizes calcium''' from the bone, increasing plasma concentrations for egg formation.
* '''Oestrogen mobilizes calcium''' from the bone, increasing plasma concentrations for [[Exotics_-_Composition_and_Formation_of_the_Egg_-_Anatomy_%26_Physiology|egg formation]].
* '''Progesterone''' secretion continues to inhibit further ovulation and stimulate behavioural changes associated with '''broodiness and incubation'''.
* '''Progesterone''' secretion continues to inhibit further ovulation and stimulate behavioural changes associated with '''broodiness and incubation'''.
* '''Prolactin''' stimulates the production of '''crop milk''' in male and female columbiformes.
* '''Prolactin''' stimulates the production of '''crop milk''' in male and female columbiformes.
