Ejaculation is the "forcible, sudden expulsion; especially expulsion of semen from the male urethra, a reflex action that occurs as a result of sexual stimulation."[1]

Ejaculation

Sperm travels from the epididymis through the vas deferens mixing with fluids from the male accessory glands as it enters the urethra. Rhythmic contractions of the pelvic floor and bulbospongiosus muscles push the semen towards the urinary meatus expelling it from the penis in several spurts.
