It seems unlikely, but if squash are fed with too much macronutrients, esp too much nitrogen, they may want to keep growing bigger and bigger and never do much in the way of reproducing. That is, take longer before they start producing fruits, and not produce as many. A certain amount of stress is what induces flowering and fruiting - "hope" for the next generation. Happy contented digesting plants don't feel as much need to attach their hopes and aspiration to their young'uns. They save it for themselves.
