Ex vivo OCT imaging of mouse epididymis. (A) Three-dimensional OCT reconstruction of the whole epididymis including caput, corpus, and cauda regions. CapE: caput epididymis, CorE: corpus epididymis, CauE: cauda epididymis. (B) OCT cross-sectional image of the epididymis showing the epididymal ducts tightly packed inside the organ. (C-E) Depth-resolved cross-sectional OCT images of the epididymal ducts within the caput (C), corpus (D), and cauda epididymis (E). The lumen and the walls of each epididymal duct are shown in green and blue, respectively. Scale bars in (A) and (B) correspond to 1 mm, and scale bars in (C-E) correspond to 200 µm.
