    Dr. Mehmet Oz answered:

    Normally, ejaculation cannons semen forward through a man's urethra and out the tip of his penis. The reason ejaculation never gets mixed up with urine is because there's a tiny muscle at the entrance of the bladder that prevents semen from slipping backwards or urine from propelling forward during orgasm (it's a roadblock of sorts, so the only way for the semen to go is out). Now, some men suffer from what's called retrograde ejaculation, in which that tiny muscle doesn't work right, causing semen to backtrack into the bladder rather than to the promised land (causes for this include some side effects of surgery or medication). Retrograde ejaculation doesn't affect a man's ability to achieve an erection or ejaculate, but it may affect his fertility.
