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

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.
