(anatomy) A blind longitudinal duct and 10-15 transverse ductules in the mesosalpinx near the ovary which represent remnants of the reproductive part of the mesonephros in the female; homolog of the head of the epididymis in the male. Also known as parovarium; Rosenmueller's organ.

The epoophoron or epoöphoron (also called organ of Rosenmüller[2][3] or the parovarium) is a remnant of the Mesonephric duct 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.[4][5]
Clinical significance
Clinically the organ may give rise to a local paraovarian cyst or adenoma.
