Leptogenesis is an attractive model for baryon synthesis. In the usual scenario, this process happens at a scale close to the GUT scale which precludes any chance of verifying leptogenesis experimentally. I will give an overview of how the scale of leptogenesis can be lowered and what is the price to pay for such a scenario to be testable experimentally.
