Fig. 10. Very high power TEM of a stage 1b embryo in vitro showing details of sperm mitochondria (original magnification x35,000). One sperm mitochondrion (arrow) has lost its matrix density and cristae and is probably degenerating. The sperm centriole (C) is duplicating. The morphology of most of the oocyte mitochondria has changed little.
