the process of ejecting or expelling semen
Term
ejaculatory duct
Definition
each ejaculatory duct passes through the prostate gland.
Term
prostate gland

lies just below the urinary bladder. where it surrounds the base of the urethra as it leaves the bladder. ducts secretes into the urethra a thin milky colored akaline secretion that enhances the motility of the sperm and to neutralize the secretions within the vagina. also the prostate gland aids in the expelling of the semen from the body.

Definition
located just below the prostate gland. also called the cowper's gland. ducts also empty into the urethra just before it extends into the penis. during sexual intercourse the glands are stimulated to secrete an alkaline mucous like fluid that provides lubrication during sexual intercourse.

procedure in which the foreskin or prepuce is removed.

of a sponge like tissue containing many blood spaces that are relatively empty during the absence of sexual arousal.
