Ovarian drilling, permant?

Hi, I just wondered if someone had their oavaries drilled to rid exccessive cysts.

1.) Do the cysts typically come back?

2.) Ovarian Drilling is listed as a one time treatment for fertility reasons.

3.) Is this supposed to be a permant treatment?

4.) Have found nothing for drilling related to treatment to manage cysts/pcos.
Only things available are for those looking to concieve.
