* Ovarian steroids, particularly oestrogens, exert a positive-feedback on the anterior pituitary gland and hypothalamus.
* Oestrogens and synthetic oestrogens are used to stimulate oestrus.
* They have a direct effect on stimulating oestrus behaviour and changes in the genital tract.
* They may also stimulate release of pituitary gonadotrophins.
* Synthetic GnRH can be used to stimulate the release of endogenous gonadotrophins.
