Sperm removed from the cauda epididymis of adult wild type and RIα+/− animals. SEM of wild type (a,b) sperm and RIα+/− (c,d) headless sperm with ruptured tails. Magnification bar=10um. (e) Percentage of sperm that are headless from wild type and RIα+/− males on different genetic backgrounds, shown as the ratio of C57BL/6:129Sv/J. N values are as follows: 99:1 (wt=10, RIα+/−=7), 50:50 (wt=1, RIα+/−=4), 6:94 (wt=3, RIα+/−=5). RIα+/− are significantly different from wild type on all backgrounds. RIα+/− on the 99:1 background are significantly different from RIα+/− on the 50:50 background. Significance level is p<0.05.
