title: Permeability of ovarian follicles to electron-dense macromolecules.
abstract: Ferritin (m.w. 500 000) perfused into the ovarian arteries of sheep permeated the theca interna and was also found in the membrana granulosa of both non-atretic and atretic Graafian follicles. Colloidal gold (m. w. 1 000 000) similarly perfused, was found in the theca interna but not in the granulosa. The results are discussed in terms of the blood-follicle barrier.
