Table 4 Effect of in-vitro exposure of buck spermatozoa to different concentrations of mercuric chloride (0.031–1.25 µg/ml) on DNA damage in sperm cells at different time intervals.

From: Collapsed mitochondrial cristae in goat spermatozoa due to mercury result in lethality and compromised motility along with altered kinematic patterns

  1. Data presented are mean ± SE of the semen samples of six bucks.
  2. Different capital superscripts in the rows indicate significant (p < 0.05) differences between the different time intervals.
  3. Different small superscripts in the columns indicate significant (p < 0.05) differences between control and different treatment groups.
