Effects of Photoperiod on Epididymal and Sperm Morphology in a Wild Rodent, the Viscacha (Lagostomus maximus maximus)
Figure 5
Epididymal corpus in gonadal regression period. (a) Semithin cut showing irregular nuclei (n) and abundant cytoplasmic vacuoles (v) in principal cells (P). Note the greater height of the epithelium in relation to that observed in the active period. L: lumen; s: stereocilia; Lp: lamina propria. TB: ×1000. (b) Scanning electron micrograph showing holes or depressions (asterisks) in the cytoplasmic surface of epithelial cells caused by marked epithelial vacuolation. L: lumen. SEM: ×3500.
