The KBrO3 is an oxidant and toxic compound that is still used, despite restrictions or prohibitions. Researchs shows it as cytotoxicity, genotoxicity, mutagenicity, teratogenicity, carcinogenicity-inducing, etc; however the data obtained in the male reproductive system are insufficient to be conclusive. In order to study the effects of protracted exposures of KBrO3 in 4 moments of a complete sperm germline cycle and red bone marrow (RBM) erythropoietic line, a group of 50 mice was randomly divided in five treatment groups of 10 mice each, which were subjected to daily injections of this chemical compound, groups were: Group I: Day 7, Group II: Day 15, Group III: Day 21, Group IV: Day 35 and Group V: Negative Control (NC). For each of these groups were performed spermatogram tests according to the WHO (2012) recommended parameters and cytotoxicity and genotoxicity tests in the red bone marrow. Statistical analyses were performed using ANOVA with Tukey post hoc test in SPSS 20.0 program. The results (mean ± SD) show that the reproductive organs significantly decrease its weight in Group III. In Group I of treatment the percentage of no motile spermatozoa number was increase (26,50±3,69 vs. 19,30±4,45 from NC), sperm vitality was reduced (68,90±2,33 vs. 75,50±1,90 from NC), and the spermatozoa with normal membrane was reduced (49,40±2,50 vs. 63,90±1,90 from NC). In Group II, the morphologically normal spermatozoa was reduced to 93,30±1,63 (vs. 96,40±0,69 from NC) and sperm concentration decreased to 49,80±3,62 million per mL (vs. 55,60±2,84 million from NC), in Groups III and IV these conditions were increased significantly showing a cumulative effect on sperm germline. The red bone marrow cytotoxicity level showed significant differences from Group I (0,6479±0,0153 vs. 0,9627±0,0102 from NC) and remained constant for the remaining treatments, genotoxicity showed cumulative effect increased with treatments from group I (16,05±1,87 vs. 3,20±1,03 from NC). The toxicity in sperm germline and toxicity in red bone marrow erythropoietic line showed no significant correlation. Therefore it is concluded that KBrO3 induces toxic effects uncorrelated in both mice cells lines reducing fertility potential and causing cytotoxicity and genotoxicity in the erythropoietic line.
