Short summary
The cow's perineal muscle is connected to the rectum, vulva, and vagina. The author hypothesizes that changes in reproductive status affect perineal muscle tension, which will affect the anatomy of the coccygeus and levator ani muscles. The sonograms we obtained showed a significant increase in the coccygeus and levator ani muscles of pyometra cows compared to endometritis, nonpartum pregnant, pregnant, and postpartum pregnant cows.
