Seminal vesicles, Epididymis, Ejaculatory duct, ductus deferens (SEED)

From the caudal (tail) end of Mesonephros. Ureter, pelvises, calcyes and collecting ducts. Fully canalized by 10th week. (from the collecting duct DOWN)
|
Very impt that it induces the metanephric mesenchyme to form kidney structures. Malformation of this leads to Potters (renal agenesis)

Induction by ureteric bud => glomerulus and renal tubules to DCTs
|
|
