UCN and endometriosis: According to Florio et al., the urocortin levels in women with endometriosis were twice as high as in women with non-endometrial ovarian cysts (median 49 pg/mL, interquartile interval 41–63 pg/mL vs. median 19 pg/mL, interquartile interval 15–23 pg/mL) and they were significantly higher in the cystic content of endometriomas compared to the peritoneal fluid and plasma [48].
