* The reflex expulsion of spermatozoa and seminal plasma from the male reproductive tract.
* The reflex expulsion of spermatozoa and seminal plasma from the male reproductive tract.
* Once intromission has been achieved, reflex impulses are initiated.
* Once intromission has been achieved, reflex impulses are initiated.
** Neural impulses derived mainly from sensory nerves in the '''glans penis'''.
** Neural impulses derived mainly from sensory nerves in the '''glans penis'''.
* Upon threshold stimulation, impulses are transmitted from the glans peinis by the '''internal pudendal nerve''' to the lumbosacral region of the spinal cord.

* Sensory impulses result in firing of nerves in the '''spinal cord'''.

* Forcing of semen into the '''urethra''' by nerves in the '''hypogastric plexus''' innervating target muscles.

* '''Emission''' and ejaculation
* '''Emission''' and ejaculation
** Emission is the movement of seminal fluids from the [[Reproductive_Tract_-Accessory_Sex_Glands_-_Anatomy_%26_Physiology|accessory sex glands]] into the pelvic urethra so that they can mix with spermatozoa.
** Emission is the movement of seminal fluids from the [[Accessory_Sex_Glands_- Anatomy & Physiology|accessory sex glands]] into the pelvic urethra so that they can mix with spermatozoa.
** Emission occurs before and during ejaculation.
