Purpose : This study was performed to compare the characteristics of digital infrared thermographic imaging(DITI) in polycystic ovary syndrome(PCOS) patients with regulary cycling controls. Methods : We studied 19 patients visiting ${igcirc}{igcirc}$ korean hospital from 7th May 2010 to 8th January 2011. The subjects were categorized in two groups. 8 PCOS patients and 11 healthy regularly cycling controls. We investigated the difference of DITI between two groups by Mann-Whitney U-test using SPSS for window (version 17.0). Results : The average temperatures of five points(In-dang(EX-HN3), GV4, GV6, GV12, GV17) between PCOS and non-PCOS groups showed a little difference though p-value is not less than 0.05. The DITI differences of PCOS group between In-dang and thorax or between In-dang and abdomen showed lower than those of non-PCOS group though not a statistical significant level. Conculsion : The results suggest that DITI differences between PCOS and non-PC OS groups need to be developed to some degree for the diagnosis tool of PCOS.
