Epoophoron

The epoophoron or epoöphoron (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 each ovary, and fallopian tube.

Epoophoron
Broad ligament of adult, showing epoöphoron. (From Farre, after Kobelt.) a, a. Epoöphoron formed from the upper part of the mesonephric body. b. Remains of the uppermost tubes sometimes forming appendices. c. Middle set of tubes. d. Some lower atrophied tubes. e. Atrophied remains of the mesonephric duct. f. The terminal bulb or hydatid. h. The uterine tube, originally the duct of Müller. i. Appendix attached to the extremity. l. The ovary.

Anatomical terminology [edit on Wikidata]

Anatomy

It may contain 10–15 transverse small ducts or tubules that lead to 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.

Histology

It has a unique histological profile.^[4][5]

Clinical significance

Clinically the organ may give rise to a local paraovarian cyst or adenoma.
