Is there a difference between seminal fluid and ejaculation?

Component of semen.: The ejaculate, or semen, is made up of sperm from the testicles & fluids from the seminal vesicles, the prostate, and the bulbourethral glands. The seminal fluid is a viscous fluid rich in fructose, making up the bulk of semen. The prostate adds a thin white fluid containing enzymes, citric acid, and lipids. The bulbourethral glands add a clear fluid. Ejaculation is the act of discharging semen.
