Slight differences in structure fundamentally change the effects, which can be corticoid, androgen, progestagen or estrogen. The latter 3 are called sex steroid hormones. Each type of sex steroid hormone is composed of a group of molecules, with slightly different effects. Sex steroid hormones are secreted by the ovary and by the adrenal gland.
