Mean serum total testosterone (T) levels on treatment days (D) 1 and 14. Subjects used one application daily of either 1 mg of micronized testosterone transdermal gel or 1 mg of testosterone propionate buccal lozenge. Blood samples were studied at hours 0 (before administration of testosterone), 1, 2, 3, 4, 6, 8, 12, 18, and 24. Diamond = lozenge D-1; square = gel D-1; triangle = lozenge D-14, X = gel D-14.

Mean serum free testosterone (T) levels on treatment days (D) 1 and 14. Subjects used one application daily of either 1 mg of micronized testosterone transdermal gel or 1 mg of testosterone propionate buccal lozenge. Blood samples were studied at hours 0 (before administration of testosterone), 1, 2, 3, 4, 6, 8, 12, 18, and 24. Diamond = lozenge D-1; square = gel D-1; triangle = lozenge D-14; X = gel D-14.

Mean serum dihydrotestosterone levels on treatment days (D) 1 and 14. Subjects used one application daily of either 1 mg of micronized testosterone transdermal gel or 1 mg of testosterone propionate buccal lozenge. Blood samples were studied at hours 0 (before administration of testosterone), 1, 2, 3, 4, 6, 8, 12, 18, and 24. Diamond = lozenge D-1; square = gel D-1; triangle = lozenge D-14; X = gel D-14.
