Anatomical and Histological Study of the Female Reproductive System (Columba oenas) during the Egg-laying Period

In this study, the female reproductive system of Columba oenas was examined during the egg laying stage, focusing on its general structure and microscopic characteristics.

Obsessive monitoring operations were performed, as well as different parts of the egg canal, which include infundibulum, magnum, isthmus, uterus and vagina.

These parts showed clear anatomical differences, each with special textile features that seem to play distinctive roles related to the growth and movement of eggs. In magnum it was found that the bulk contains clear mucous folds and many secretory glands. The isthmus had a star-shaped lumen and was lined with a false cylindrical epithelium. In the uterus, branching tube glands, rich in multiple mucous sugars are observed, which are likely to contribute to the process of cortex formation. The vaginal area showed longitudinal folds consisting of cylindrical epithelial fabric. These changes combined indicate that the reproductive system adapts structurally while laying eggs to support the needs and laying eggs.
