This video demonstrate laparoscopic ovarian drilling for PCOS (Polycystic Ovary Syndrome) Treatment. The exact mechanism of Ovarian Drilling in PCOS is yet to be elucidated. The most plausible one is the destruction of ovarian follicles and stroma resulting in a decrease in androgen and inhibin levels and a secondary rise in follicle-stimulating hormone (FSH) levels. Production of inflammatory growth factors like insulin-like growth factor-1, in response to thermal injury is in Laparoscopic Ovarian Drilling to Treat PCOS Infertility, further potentiates the actions of FSH on folliculogenesis, while increased blood flow to the ovary provoked by surgery, facilitates increased delivery of gonadotropins. The number of punctures is empirically chosen depending on the ovarian size. In the original procedure, 3-8 diathermy punctures (each of 3 mm diameter and 2-4 mm depth) per ovary were applied, using power setting of 40W W for 2-4 s
