Histological comparison of uterovaginal junction (UVJ) folds containing sperm storage tubules (SST) stained with hematoxylin and eosin between day 3 and day 9 after artificial insemination (AI) in chicken hens. The epithelium of UVJ folds and SST were pseudostratified ciliated columnar (pointed with bold arrows) and simple columnar, respectively. Sperms were gathered and distributed in the lumen of SST (pointed with narrow arrows) as shown in at day 9 (A) and at day 3 (B) post AI. Scale bar = 100 μm.
