From Sperm to Semen
During male orgasm and ejaculation sperm travel from the epididymi upwards through the vas deferens and then down into the upper portion of the prostate. The sperm and fluid from the seminal vesicles then mix with prostatic fluid and fluid from the bulbourethral glands to form the semen. The ejaculate now containing sperm and fluids from the seminal vesicles prostate and bulbourethral glands flows from the ejaculatory ducts into the urethra. From the urethra it passes out through the end of the penis.
