If sperm cooperate, I wonder if the effects of the reported[1] historical decreasing sperm counts are worse than thought. For example, if the value drops by half, perhaps the decrease in fertility is not linear, but quadratic, falling to 1/4 of the original value, because each of the 50% left has only half the average number of peers to cooperate (this is only an example. I have no idea on how fertility scales with sperm counts).
