The dissolution of the nuclear envelope (NE) has been studied ultrastructurally in mouse oocytes maturing in vitro. NE breakdown begins with the undulation of the nuclear envelope followed by the disappearance of nuclear pores. Subsequently, extensive NE convolutions, possibly caused by impinging microtubules, result in the apposition of adjacent NE segments, the appearance of breaks and the formation of NE doublets. Doublets may also be formed by the apposition of intranuclear cisternae to the inner leaflet of the NE. Nuclear envelope breakdown in mouse oocytes takes approximately three and one‐half hours in vitro.
