Epididymis and Ductus Deferens (vas deferens)

The spermatoza leave the testis and enter the epididymis. It is a single, coiled duct that is continuous with the ductus deferens.

Ductus deferens is a thick walled muscular tube connecting the epididymis with the prostate.

MH 182 Seminal Vesicle and Ductus Deferens

Seminal Vesicle

The seminal vesicle is an unbranched coiled tubular gland that secretes a mucoid substance high in fructose (for sperm nutrition).

Prostate

The prostate is a branchd tubular gland that adds secretions to the sperm during ejaculation of semen.

Penis

The penis is composed of three cylindrical bodies of errectile tissue surrounding the urethra.
