Sperm motility, sperm count and histological change of testes showed a significant increase in the control group compared to CdCl2 GT and GT plus CdCl2. Results are represented as Mean±SEM. Statistical significance is indicated; a-b Mean in the same column carrying different superscript letters are significantly different (p<0.05). Data for each time point was repeated for n= 6 times.
