(A) Histology, (B) mean seminiferous tubule diameter (MSTD) and mean testicular biopsy score (MTBS) of the testis in the groups of male mice exposed to smoke and administered coenzyme Q₁₀ supplementation. Values are presented as the means ± SD (n=6/group). #Indicates a significant difference between the air- and smoke-exposed groups (AV vs. SV and AQ vs. SQ); *Indicates a significant difference between the vehicle and coenzyme Q₁₀ supplementation groups (AV vs. AQ and SV vs. SQ). MSTD: mean seminiferous tubule diameter. MTBS: mean testicular biopsy score.
