Introduction
Draft Page - notice removed when completed.
The male internal genital tract leaving each of the male testis is the ductus deferens (vas deferens; Latin "carrying-away vessel"; plural: vasa deferentia).
The excretory duct of the testis that is the continuation of the canal of the epididymis. Develops from the paired mesonephric ducts (Wolffian ducts).
Anatomically beginning at the lower part of the tail of the epididymis it is at first very tortuous, but gradually becoming less twisted it ascends along the posterior border of the testis and medial side of the epididymis, and, as a constituent of the spermatic cord, traverses the inguinal canal to the abdominal inguinal ring.
There are also separate pages describing: Y Chromosome | spermatozoa | testis | epididymis | ductus deferens | prostate | penis | Category:Male
