This actually does line up with evolutionary theory - females evolve factors that allow them to more selectively control which males they mate with, while males evolve factors to defeat female selective processes. It’s why female ducks have corkscrew vaginas and male ducks have “explosive” erections.
Of course, the key word there is “selectively control”. The females don’t reject males outright, just ones they don’t consider fit for breeding.
