| Anatomical terminology | |
The epoophoronorepoöphoron (also called organ of Rosenmüller[2][3] or the parovarium; pl.: epoophora) is a remnant of the mesonephric duct that can be found next to the ovary and fallopian tube.
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 ducts 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.
It has a unique histological profile.[4][5]
Clinically the organ may give rise to a local paraovarian cystoradenoma.
