Fig. 1. Sketch showing a transverse section through the right and left Wolffian ducts in a human fetus 80.3 mm crown-rump length

Estimated age 13 weeks (Carnegie Collection, no. 768(3). Enlarged 100 diameters. The primordium of the left seminal vesicle can be seen extending as a lateral evagination from the Wolffian duct of that side. The primordium of the right seminal vesicle is also shown and is cut in a broader portion, its lumen being separated from that of the Wolffian duct by a slight ventral sulcus.

Abbreviations: A or Amp, ampulla ductus deferentis F., prostatic furrow D.D. or D. def., ductus deferens (vas L, left side deferens) Rt, right side D.E. or D. ejac., ductus ejaculatorius U., utriculus prostaticus D.W., ductus Wolfii V.S. or V. sem., vesicula serninalis GL., glandula V.U., vesica urinaria
