What is dose fractionation?

So dose fractionation we already do it routinely for all of our patients and the reason—what dose fractionation is, is when we give radiation, you can either give the whole radiation dose in one shot or you can cut it up into smaller doses over several days or weeks even. And you usually have lower side-effects or toxicity if you do does fractionation and so we routinely do it. Whether it has any effects on fertility, I’m not exactly sure. I don’t think there have been studies showing whether that is a good option, but it’s routine at this point in time.
