The purpose of a plant seems to be to reproduce itself.

I have heard that some plants "get frustrated" after years of not producing 
seed and "fix" the problem. 

We are not allowed to grow the "sterile" forms of the invasive buckthorn here 
in Minnesota because they tend to revert to seed production when they get 
"old." 

Some isolated "female" dioecious plants will grow a branch of "male" flowers 
so as to be able to make viable seeds.

I don't know what the pears might be doing to pull this off.

 So so you believe the tree to be self fertile?  That is
 something I've not
 heard of but I certainly consider it possible.  When
 isolated pear trees
 have born fruit here, I never have even checked their seeds
 so I really am
 only speaking from the literature.
