Oocytes in ovarian atretic follicles now and then show in their cytoplasm nucleuslike formations. The appearance of those pseudonuclei in the rat is described by light-and electron microscopy. Every pseudonucleus contains one or more Feulgen positive particles, and is surrounded by a membrane on its surface. The pseudonuclei are formed in the course of degeration of the oocyte during 1. und 2. meiotic metaphase from contracted chromosomes, probably with the involvement of the mixoplasma.
