Fig. 4.

Presentations of the morphological anomalies of CBAVD and CUAVD. Three presentations of CBAVD and two presentations of CUAVD are morphologically identifiable based on the absences reported by imaging of the vas deferens alone (indicated in red). Possible absences of a kidney and/or one or both seminal vesicles are represented by the organs with dotted lines. Other potentially associated anomalies such as absences from the body and/or tail of the epididymis, the ampulla of the vas deferens and the ejaculatory ducts are not taken into account. E epididymis, K kidney, T testis, U urethra
