Abstract

The vas deferens, also known as the ductus deferens or spermatic duct, is a tubular ­conduit that begins at the tail of the epididymis and ends by joining the excretory duct of the seminal vesicle to form the ejaculatory duct. During the in situ inspection on an autopsy of a preterm infant or fetus, prior to testicular descent, the vas deferens is grossly recognized as a thin structure traveling from the tail of the epididymis over the ipsilateral umbilical artery toward the midline and terminating posterior to the urinary bladder at the base of the prostate. After testicular descent, the vas deferens can be seen emanating from the internal inguinal ring and terminating again at the prostatic base.
