Histological structure of intact ovaries. Ovarian follicles in different stages of development (primary (1), preantral (2), and antral (3) follicles) and corpora lutea (4) were separated by a stroma (S). The environment of antral follicles is homogeneous with poor eosin staining. The medulla of ovaries (M) consisted mainly of loose connective tissue and blood vessels. Hematoxylin and eosin staining.
