No research on it: Saliva could kill sperm (pretty much anything could kill sperm). Haven't seen any research studies on cold water, saliva, and sperm. Such research would be hard to make sense of, because there would be too many variables, such as: how much saliva, how many sperm, how much water, how cold the water, etc... There will always be unknowns in life, except that life can be full of surprises.
