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.
