* In females, '''FSH''' is mainly responsible for follicular growth.
* In females, '''FSH''' is mainly responsible for follicular growth.
* 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 oocyte.

* '''Oestrogen mobilizes calcium''' from the bone, increasing plasma concentrations for egg formation.

* '''Progesterone''' secretion continues to inhibit further ovulation and stimulate behavioural changes associated with '''broodiness and incubation'''.
