No, actually. A rooster's testicle is actually INSIDE his body cavity, unlike mammals. But being inside his body cavity does not make him infertile, no.

The undigested waste products does not enter your body cavity. That is called as faecal matter. Scientifically speaking the food you eat is not "Inside" your body cavity. It is always "Outside" the body cavity. You go for extracellular type of digestion. I found it very difficult to teach the same in my dental college class.
