Fig. 8. Transmission electron microscopy of mice spermatozoa. Nuclei of mice sperm incubated in the presence of IVFM (a) or DMSO (d) were uniformly electron-dense and fully condensed, with an intact nuclear envelope and outer membranes. The microphotographs depict well defined mitochondria and flagellum membranes in sperm with IVFM (b, c) or DMSO (e, f).
