Female reptiles are known to safeguard sperm for long periods of time with turtle sperm storage documented up to four years. By keeping sperm from a previous mate—sometimes two mates—females do not have to expend energy copulating again before laying subsequent clutches. It is also hypothesized that they can selectively fertilize eggs choosing one father over another.
