Scanning Electron Microscope images of goat spermatozoa in-vitro treated with Hg (0.031 µg/ml HgCl2) showing intact head and tail and normal surface morphology (a), intact acrosome (b) and intact midpiece (c) after 15 min exposure. While wrinkled plasma membrane on head region (d,e) and middle piece deformities and focal area of membrane rupture at middle piece were more obvious after 3 h exposure of mercury (f).
