title: Comparison of abdominal skin temperature between fertile and infertile women by infrared thermography: A diagnostic approach.
abstract: This retrospective study aimed to evaluate the differences in abdominal temperature (AT) between fertile (n=206; age) and infertile (n=250) women between the ages of 30 and 39 years. We evaluated the differences in two distinctive skin temperatures by thermography: ΔT1(CV8 index) - difference in temperature between the mid-abdomen (CV8 acupuncture area) and ventral upper arm (VUA) and ΔT2(CV4 index) - difference in temperature between the lower abdomen (CV4 acupuncture area) and VUA. The results indicated that the ΔT1and ΔT2of infertile women were significantly lower (by 1.05°C and 0.79°C, respectively; p<0.001, both) compared to those of fertile women. Additionally, the area under the curve of ΔT1(0.78) was greater compared to that of ΔT2(0.736), and its threshold was set at 0.675°C, by which, the sensitivity and specificity of ΔT1for determination of fertility were found to be 80.8% and 68.4%, respectively. In conclusion, infertility is associated with lower AT. The decrease in AT in infertile women might be due to poor blood perfusion to the core muscles and tissues of the body. These findings provide a basis for further research for evaluation of clinical feasibility of thermography for analysis of infertility in women. Further evaluation of the influence of AT on fertility outcomes is required to determine the causal relationship between AT and infertility.
