Nothing. The bladder is essentially a bag which stores urine, it is fed by the two kidneys and it drains out along the urethra, which passes through the prostate gland, then along the length of the penis and out through the small opening in its tip. During and ejaculation sperm travels from the testes along a tube called the vas deferens until it reaches the prostate gland, here the vas deferens connects with the urethra. Put simply the prostate gland acts rather like the points system on a railway track. When the penis is soft the prostate allows liquid from the bladder to pass along the urethra and out of the penis, when the penis is erect the prostate effectively stops the flow of urine and instead allows the flow of semen into the urethra and along the penis. This mechanism prevents the two fluids from mixing, this is necessary as urine is quite effective as a spermicide.
