Most people think about it in terms of females evolving to "hide" their fertile window for some reason, maybe to trick males into to staying with them or something. Isn't it more likely that advertising was lost because it simply became unnecessary? Maybe we evolved to mate throughout the menstrual cycle first and this then made advertising fertility unnecessary. The loss of female fertility advertisements is a strange thing.

By regularly copulating with his mate a man would ensure that her reproductive tract was constantly filled with his sperm and minimise the chances of her being fertilised by other men she had sex with when he wasn't around. Doesn't that count as a kind of sperm competition or are you only talking about specific adaptations that sperm cells may have to compete with other sperms?
