Fig. 4. Effects of endosulfan on sperm chromatin decondensation. Percentage of decondensed capacitated sperm after treatment with different concentrations of endosulfan (100 pM, 10 nM, 1 μM, 100 μM) for 15 minutes. A: AI, B: endosulfan Master®, C: endosulfan Zebra Ciagro®. Controls consisted of capacitated sperm incubated in the presence of IVFM or DMSO alone. The results are expressed as mean ± SEM (n = 5, Master®: **p < 0.001, Zebra Ciagro®: ***p < 0.0001).
