Oxidative stress status in normal ovarian cortex surrounding ovarian endometriosis

Expression levels of 8-hydroxydeoxyguanosine, a sensitive indicator of DNA damage resulting from oxidative stress, were significantly higher in samples of normal ovarian cortex surrounding endometriotic cysts when compared with ovarian cortex surrounding dermoid and serous ovarian cysts. These findings suggest that the normal ovarian cortex surrounding endometriotic tissues is more severely affected by oxidative stress than ovarian cortex adjacent to other benign ovarian cysts.
