PCOS, but never ovulate?

Fokpop
Hi,
​New in TTC. New in all of this, sorry in advance for my stupid question.
Doctor said i am having PCOS.  Lotsa small eggs, but never ovulate. Thus, having  irregular AF .
​My question ,
​For woman with PCOS  
​How did eggs burst into AF, if she really never ovulate  ?
​PCOS woman must ovulate somehow rite to get their eggs off?
