Effects of Photoperiod on Epididymal and Sperm Morphology in a Wild Rodent, the Viscacha (Lagostomus maximus maximus)
Figure 1
Epididymal segments in the active period. (a) Image showing the organization of a section of initial segment obtained by scanning electron microscope. Note the greater height of the epithelium (Ep) and the thickness of the lamina propria (asterisk) below the epithelium. L: lumen; s: stereocilia. SEM: ×600. (b) Semithin cut of a section of epididymal caput emphasizing the presence of abundant lipid droplets (arrowhead) and dense bodies (arrow) in the cytoplasm of principal cells. Numerous sperm are stored in the epididymal lumen (L). TB: ×400.
