Abstract

   Depleted uranium (DU) projectiles have been used in battle in Iraq and the Balkans and will continue to be a significant armor-
penetrating munition for the US military. As demonstrated in the Persian Gulf War, battle injury from DU projectiles and shrapnel
is a possibility, and removal of embedded DU fragments from the body is not always practical because of their location in the body
or their small size. Previous studies in rodents have demonstrated that implanted DU mobilizes and translocates to the gonads, and
natural uranium may be toxic to spermatazoa and the male reproductive tract. In this study, the effects of implanted DU pellets on
sperm concentration, motility, and male reproductive success were evaluated in adult (P1) Sprague–Dawley rats implanted with 0,
12, or 20, DU pellets of 1 Â 2 mm or 12 or 20 tantalum (Ta) steel pellets of 1 Â 2 mm. Twenty DU pellets of 1 Â 2 mm (760 mg)
implanted in a 500-g rat are equal to approximately 0.2 pound of DU in a
