Vesicular appendages of epoophoron

Vesicular appendages of epoophoron or parovarium are small vesicles found in the broad ligament of the uterus, between the epoophoron and uterus. They are remnants of the Wolffian duct, which is present in the early development of the female reproductive system.

Anatomy

The vesicular appendages of epoophoron are located in the broad ligament of the uterus, between the epoophoron and the uterus. They are small vesicles that are remnants of the Wolffian duct, which is present in the early development of the female reproductive system.

Development

During the early development of the female reproductive system, the Wolffian duct forms the vesicular appendages of epoophoron. These vesicles are remnants of the Wolffian duct, which eventually atrophies in females.

Function

The function of the vesicular appendages of epoophoron is not well understood. They are thought to be vestigial structures, meaning they have lost most or all of their original function through evolution.

Clinical significance

In some cases, the vesicular appendages of epoophoron can become cystic, leading to a condition known as parovarian cyst. This condition is usually benign, but can cause symptoms such as pelvic pain and abnormal bleeding.
