A Harvard University study claims that men who routinely eat bacon or sausage are damaging their sperm.

Expected to be presented at a meeting for the American Society for Reproductive Medicine in Boston this week, the study examined the diets of 156 men who were going through in vitro fertilization treatments. Only 5.5 percent of men who ate processed meat regularly had "normal" sperm cells while over 7 percent who ate less actually did. 

On the other hand, people who eat fish routinely had much better sperm quality. The long and short of this is that processed meat is bad for your sperm and fish is good for it. There's a pretty obvious reference to cunnilingus there if you' have a dirty mind, but monitor your diet if you want to have kids regardless.
