Little sperms? where do they go?

sperm inside mens testicles i guess swim around inside the testicles. What happens to sperm that becomes too old? like after a while if it does not get ejeculated out does the body get rid of it? or does it live long term??

no flaming pls
i'll appretiate any scientific replies 2 this :)

That was fairly amusing, but the larger point is that your entire body is a womb and grave for cells.  About every 7 years, enough of your cells have died and been replaced by cytogenesis that you could be considered essentially a new person, chemically.  Literally, new (at least, new-to-your-body) atoms and molecules had replaced the ones you had before in your cells.  Of course, what doesn't change is your structure.  You may get a new liver in 7 years, but you'll still have the same long-term problem structures like pre-cancers and such.  Cancer cells replace themselves in the same way normal cells do; they're just more militant about it.
