As a result, the muscles in his prostate gland, seminal vesicles (both of which produce seminal fluid), and vas deferens (the tube that connects the testicles to the urethra) contract rhythmically, moving semen through those glands and the urethra and, finally, out of his body during ejaculation, a process controlled by the sympathetic nervous system.
