Probably. Studies show that circumcision significantly reduces the risk of a man acquiring HIV from heterosexual contact. (At least in Africa, where most HIV is transmitted heterosexually, and most of these studies have been done.)
Here's an abstract. Obviously, that's not the only way, or even the best way to avoid getting HIV. But I do believe there is evidence that circumcised men are also less likely to get and transmit other STDs. I'll try to find some references.
There's
Apligraf. It's a skin substitute used to cover diabetic skin ulcers, burns, and other slow-to-heal wounds. It's made of living fibroblast cells harvested from donated infant foreskins. It's a useful product that would be less available and more expensive if there were fewer circumcisions.
And maybe I'm going out on a limb here, but I think that Americans--both men and women--generally consider a circumcised penis more aesthetic. (Might be an interesting poll.

)
But I don't think any of these justify infant circumcision as a routine procedure.
