You should do what I found out on this (or another) newsgroup several years ago:
When you get both male flowers (regular stems) and female flowers (stems that look like little zucchini), take a small paintbrush, use it to get pollen from a male flower (inside it, at the stamen) , and brush it on a female flower (inside it, on whatever it's called). You'll get the idea. It will increase your squash yield by a bunch.
