Effects of Photoperiod on Epididymal and Sperm Morphology in a Wild Rodent, the Viscacha (Lagostomus maximus maximus)
Figure 9
Normal sperm morphology of viscacha. (a) Sperm obtained from the epididymal fluid and observed by light microscopy. Bright green staining. Asterisk: equatorial segment. ×1000. (b) Image obtained by scanning electron microscope showing a normal sperm located inside of the epididymis and anchored to the stereocilia (s) of the epithelium. Note the apical thickening (arrowhead) of the sperm head and the mitochondrial sheath (m) placed in the middle part of the flagellum. In the sperm head acrosomal (A) and postacrosomal (Ap) regions are identified. Asterisk: equatorial segment. SEM: ×10.000.
