This structure is derived from the Wolffian duct ( Mesonephric Duct ) as opposed to the appendix testis which is derived from the M�llerian duct ( Paramesonephric Duct ) remnant.

The caudal parts of the paramesonephric ducts fuse into a single tube, known as the uterovaginal primordium, before flowing into the dorsal aspect of the urogenital sinus at the sinus tubercle directly medial to the mesonephric ducts.

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.

I personally am looking forward to the day when a reader can view a wikidata-based " tree ", clicking mesoderm and seeing all of the derived structures, then selecting the intermediate mesoderm, then Pronephric duct, mesonephric duct and vas deferens.

This structure attaches to the inferior portion of the testis and extends to the labial sacral fold of the same side at the same time, a portion of the embryonic mesonephric duct adjacent to the testis becomes attached and convoluted informs the epididymis.

Each of these consists of a glomerulus, a tuft of capillaries which arises from lateral branches of dorsal aorta and drains into the inferior cardinal vein; a Bowman's capsule, a funnel like structure which surrounds the glomerulus; and a " mesonephric tubule ", a tube which connects the Bowman's capsule to the mesonephric duct.
