I thought it did, but when I tested this out for myself, really it didn't work as I was keeping track of my EV's. You may get a different answer but this is just my own experience.
Now for my question to anyone to answer, what exactly does Life Orb do?
Why don' you try reading the item descriptions thread next time to stop causing these useless questions? Life Orb adds an extra 1.3 damage to your attacking pokemon, but it loses 10% of its health everytime it uses a move to attack an opponent.
