Ductus deferens

The vas deferens aka ductus deferens help transport sperm from the epididymis, during ejaculation. The spermatic cord surrounds the vessels that run from the abdomen to the testicles. The seminal vesicles are glands that secrete semen, which forms most of the seminal fluid

Ductus Deferens, Spermatic Cord and Seminal Vesicles[edit | edit source]

Ductus Deferens[edit | edit source]

It is a long muscular duct that transports sperm from the tail of the epididymis to the ejaculation duct
It ascends from the scrotum, into the spermatic cord and through the inguinal canal
Then, it bends medially around the inferior epigastric artery
It crosses the ureter posterior to the bladder
Then, it is joined by the duct from the seminal vesicle to form the ejaculatory duct
The duct expands to form the ampulla

Spermatic Cord[edit | edit source]

It consists of:-

Ductus deferens
Testicular artery
Pampiniform plexus
Cremasteric vessels
Genital branch of the genito-femoral nerve

Layers:-

External spermatic fascia
Cremasteric fascia
Internal spermatic fascia

Seminal Vesicle[edit | edit source]

It is an accessory gland
It is encapsulated in connective tissue
It joins the ductus deferens to form the ejaculatory duct
It is lined by pseudo-stratified columnar epithelial cells
