In this structure, DES exposure can disrupt Msx2-dependent apoptosis during development, and Gartner cysts are derived from its remnants.  GDNF induces caudal budding in this structure, which develops as a solid cord of cells from the mesonephros and subsequently forms a tube.

GDNF induces caudal budding in this structure, which develops as a solid cord of cells from the mesonephros and subsequently forms a tube.  Bisphenol A promotes the retention of this structure in females. A hormone secreted by the Leydig cells promotes the differentiation of this structure, and, if AMH is not expressed, it begins to degenerate about ten weeks after conception.  For 10 points, name this embryonic ductal system which develops into the epididymis, seminal vesicles, and vas deferens in the presence of testosterone while the Mullerian system degenerates.
