Oestrone (Estrone) is one of the three naturally occurring oestrogens (estrogens), the others being oestradiol (estrodiol) and oesteriol (estriol).
Oestrone is produced primarily from androstenedione originating from the gonads or the adrenal cortex.
In premenopausal women, more than 50% of the oestrone is secreted by the ovaries.
In prepubertal children, men and non-supplemented postmenopausal women the major portion of oestrone is derived from peripheral tissue conversion of androstenedione.
The oestrone test is ordered to evaluate postmenopausal vaginal bleeding due to peripheral conversion of androgenic steroids as well as to guide female hormone replacemnt therapy.
