Acute effect of TiNP on testicular function. Male C57BL/6J mice (n = 5) were injected with TiNP (2, 10, 50 mg/kg; i.v.) once a week for 4 weeks, and were sacrificed at 3 days (a); 9 days (b); or 90 days (c) after the final injection. Control mice received DSP (0.1 ml/20 g body weight). Mice received single IT injection of TiNPs (20, 100, or 500 μg/mouse), and were sacrificed 3 days later (d). Sperm motility (motility percent) and sperm numbers (in cauda epididymis) are shown. Results from (a) was derived from a previous paper. In two experiments (b,c), C57BL gpt delta mice were used. *, **, significantly different from control (*p < 0.05; **p < 0.01).
