Effects of Photoperiod on Epididymal and Sperm Morphology in a Wild Rodent, the Viscacha (Lagostomus maximus maximus)

Figure 3

Epididymal segments in the gonadal regression period. (a) Semithin cut of a section of epididymal caput showing principal cells (P) with low cellular activity. Their nuclei (n and arrow) are elongated and have scarce cytoplasmic content. B: basal cell (arrow); H: halo cell (arrow); Lp: lamina propria; v: blood vessel; L: lumen. TB: ×400. (b) Note the clustered arrangement of the stereocilia (s) of principal cells (P) and the poor presence of sperm (sp) stored in this segment. Asterisks: lipid droplets. L: lumen. TB: ×1000.
