Estriol is a metabolite of 17β-estradiol with much lower biological activity. It is the primary estrogen found in the urine. Large quantities of estriol and estrone are produced by the placenta during pregnancy. These are also the primary estrogens produced by adipose tissue in men and in post-menopausal women.
