Clinic significance

Estrone is both secreted by the ovary and (about 30% in females) generated by the conversion of precursors like estradiol and delta-4 androstenedione. In menstruating women, estrone levels are lower than those of estradiol but this situation is reversed following menopause when estrone becomes the predominant estrogen. Since there is no more ovarian production, all of the estrone is derived from the peripheral metabolism of delta-4 androstenedione. This test is part of the menopause estrogen profile.
