Laparoscopic ovarian drilling also called Laparoscopic ovarian diathermy is not common, but it is a minimally invasive treatment that is an option for women with PCOS that are still not ovulating after losing weight or using fertility medicines/anti-oestrogen treatment. 

Electrocautery (using heat from an electric current) or a laser is used to destroy parts of the ovaries to restore regular ovulation cycles. Studies indicate the treatment is effective in approximately 50% of cases.
