Vagina.
Vagina of a sexually immature subadult harbor porpoise (Phocoena phocoena). The animal is positioned in a dorsal recumbency. The reproductive tract was opened with an incision along the central midline. The vagina is divided into a cranial and caudal region by a prominent vaginal fold that runs the circumference of the lumen. The cranial vagina has several small vaginal folds. The caudal vagina has a few vaginal folds proximate to the largest vaginal fold.

The reproductive tract was opened with an incision along the central midline. The vagina is divided into a cranial and caudal region by a prominent vaginal fold that runs the circumference of the lumen. The cranial vagina has several small vaginal folds.

Vaginal folds.
Vagina of a sexually mature pregnant harbor porpoise (Phocoena phocoena). The animal is positioned in a dorsal recumbency. The reproductive tract was opened with an incision down the central midline. The vagina is divided into a cranial and caudal region by a prominent vaginal fold that runs the circumference of the lumen. Only the cervix and cranial vagina are in this image to highlight the development and depth of the cranial vaginal folds.

Vagina.
Vagina of a sexually mature pregnant harbor porpoise (Phocoena phocoena). The animal is positioned in a dorsal recumbency. The reproductive tract was partially opened with an incision down the central midline from the clitoris to the largest vaginal fold. The largest vaginal fold is centered in cross-section to highlight its spiraling nature.
