EM images of Rnf133 HET/KO sperm in the epididymis. Rnf133 KO sperm have cytoplasm around normal-shaped nuclei (arrows) and retain abnormally massive cytoplasm involving vacuoles and organelles (arrowheads). This experiment was replicated with a minimum of three mice per genotype, and representative images are shown
