There is a lot of unknown information about endometriosis and a lot is known but not commonly shared which is what I am going to do today. 1.) Inguinal endometriosis is a rare condition, accounting for 0.3%–0.6% of patients affected by endometriosis, with fewer than 60 cases reported in the literature. inguinal Endometroisis usually presents as painful/tender inguinal mass and is most often mistaken for incarcerated hernia and other inguinal lesions 2.) Endometrisis can spread to the lungs and brain 3.) endometrisis has been found in males but Only a few cases of endometriosis in me n have been reported in the literature 4.) endometrisis has been found in infants 5.) Women in the deep endometriosis group had a statistically significant excess of blue eyes and a reduced proportion of brown eyes
