Ductuli aberrantes
Encyclopedia
Ductuli Aberrantes.—A long narrow tube, the ductulus aberrans inferior (vas aberrans of Haller), is occasionally found connected with the lower part of the canal of the epididymis
, or with the commencement of the ductus deferens.
Its length varies from 3.5 to 35 cm., and it may become dilated toward its extremity; more commonly it retains the same diameter throughout.
Its structure is similar to that of the ductus deferens.
Occasionally it is found unconnected with the epididymis.
A second tube, the ductulus aberrans superior, occurs in the head of the epididymis; it is connected with the rete testis
.
Epididymis
The epididymis is part of the male reproductive system and is present in all male amniotes. It is a narrow, tightly-coiled tube connecting the efferent ducts from the rear of each testicle to its vas deferens. A similar, but probably non-homologous, structure is found in cartilaginous...

Rete testis
Rete testis is an anastomosing network of delicate tubules located in the hilum of the testicle that carries sperm from the seminiferous tubules to the vasa efferentia....
