Figure 1. Distribution of spermatozoa in the oviduct of P. sinensis during the hibernation season (January), H&E staining and TEM.

Figure 1

(A) Spermatozoa stored within the oviduct. (B) Spermatozoa were embedded among the cilia of the oviduct. (C) Spermatozoa stored in both the SST and lumen of the oviduct. (D) Spermatozoa were embedded among the cilia of SST. (E,F) Many spermatozoa were embedded among the cilia. Cilia (Ci), epithelium (*), gland cell (G), lumen (L), spermatozoa (Sp), secretory cell (SC), ciliated cell (CC). Scale bar = 50 μm (C), 20 μm (A), 10 μm (B,D), 2 μm (E) and 1 μm (F).
