mes·o·neph·ric duct

a duct in the embryo draining the mesonephric tubules in the mesonephros; in the male, it becomes the ductus deferens; in the female, it becomes vestigial.
See also: longitudinal duct of epoophoron.

Wolffian duct

n.
The embryonic duct of the mesonephros, which in the male becomes the vas deferens and in both sexes gives rise to the ureter.
An embryonal duct that forms from the 25–30th days of gestation in association with the rudimentary pronephros, later becoming the mesonephric excretory duct, the ‘second embryonal kidney’, giving rise to the male reproductive system—rete testis, efferent ducts, epididymis, vas deferens, seminal vesicles. In females, the lack of testosterone results in Wolffian duct regression at the 10–11th week, a portion of which remains as embryonal ‘rests’—Gartner’s duct cysts, epoophoron, Skene's glands, paroophoron

mes·o·neph·ric duct

(mez'ō-nef'rik dŭkt)
A duct in the embryo draining the mesonephric tubules; in the male, it becomes the ductus deferens and ureter; in the female, it becomes the ureter's vestigial structures.
Synonym(s): wolffian duct.

Wolffian duct

the duct from the mesonephros in vertebrates. In fish and amphibia, it forms the urinary duct in females, and the urinogenital duct in males. In reptiles, birds and mammals it forms the VAS DEFERENS in males, and degenerates in females.

Mesonephric duct occupied between testis and mesonephros and shifted to primary bladder.
In its confirmation, Noden [3,10,19] have pointed to the fact that atrophy of mesonephros, part of the mesonephric duct within mesonephros remains in connection with the testis and finally formed epididymis [3,10,19].
The paramesonephric ducts have regressed leaving only the mesonephric ducts that become connected with the testes via a few remaining tubules of the mesonephros.
In females the mesonephric ducts degenerate and by twelve weeks due to lack of testosterone and the paired paramesonephric developed on lateral aspect of mesonephrons to reach urogenital sinus at nine weeks and unfused lateral arms of paramesonephric ducts forming fallopian tubes.
Mesonephric duct The tubule that drains from the embryonic kidney (mesonephros) to the cloaca in the embryo.
Initially three parts can be recognized in each duct (a) a cranial vertical portion that opens into the abdominal cavity (b) a horizontal part that crosses the mesonephric duct (c) a caudal vertical part that fuses with its partner from the opposite side with the decent of the ovary.
