^*Sperm concentration was determined by mincing 1 epididymis into 2 ml of PBS, and counting after 1 hour.

^{^}The percentage of abnormal sperm was determined by counting 100 sperm from each mouse. The following groups of animals were littermates: (1,2,6,7); (3,11,12); (4,5,8,9). Animals 10 was sired by the same parents as 11 & 12. All males were 2–4 months of age.
