Abstract
Summary
The metabolism of estradiol-17β-4-14C was studied in a rhesus monkey during the follicular stage of the menstrual cycle. The major portion of the injected dose was excreted in the urine during the first 24 hours as glucuronosides. Estradiol-17β and estrone were the principal radioactive estrogens found in this fraction of the urine. Smaller amounts of the radioactivity were identified as estriol and 16-epi-estriol.
