Veterinary aspects
OCD also is found in animals, and is of particular concern in horses, as there may be a hereditary component in some horse breeds. Feeding for forced growth and selective breeding for increased size are also factors. OCD has also been studied in other animals—mainly dogs, especially the German Shepherd—where it is a common primary cause of elbow dysplasia in medium-large breeds.In animals, OCD is considered a developmental and metabolic disorder related to cartilage growth and endochondral ossification. Osteochondritis itself signifies the disturbance of the usual growth process of cartilage, and OCD is the term used when this affects joint cartilage causing a fragment to become loose.According to the Columbia Animal Hospital the frequency of affected animals is dogs, humans, pigs, horses, cattle, chickens, and turkeys, and in dogs the most commonly affected breeds include the German Shepherd, Golden and Labrador Retriever, Rottweiler, Great Dane, Bernese Mountain Dog, and Saint Bernard. Although any joint may be affected, those commonly affected by OCD in the dog are: shoulder (often bilaterally), elbow, knee and tarsus.The problem develops in puppyhood although often subclinically, and there may be pain or stiffness, discomfort on extension, or other compensating characteristics. Diagnosis generally depends on X-rays, arthroscopy, or MRI scans. While cases of OCD of the stifle go undetected and heal spontaneously, others are exhibited in acute lameness.
The epoophoron or epoöphoron (also called organ of Rosenmüller or the parovarium) is a remnant of the mesonephric tubules that can be found  next to the ovary and fallopian tube. Anatomy
It may contain 10–15 transverse small ducts or tubules that lead to the Gartner’s duct (also longitudinal duct of epoophoron) that represents the caudal remnant of the mesonephric duct and  passes through the broad ligament and the lateral wall of the cervix and vagina. The epoophoron is a homologue to the epididymis in the male. While the epoophoron is located in the lateral portion of the mesosalpinx and mesovarium, the paroophoron (residual remnant of that part of the mesonephric duct that forms the paradidymis in the male) lies more medially in the mesosalpinx. Histology
It has a unique histological profile. Clinical significance
Clinically the organ may give rise to a local paraovarian cyst or adenoma. See also
