Gene expression of aromatase, SF-1, and HSD17B2 in menstrual blood as noninvasive diagnostic biomarkers for endometriosis

Endometriosis diagnostic delays are still encountered due to the lack of a reliable, noninvasive diagnostic test. Besides, menstrual blood is a relatively untapped field for diagnostics, yet it provides a readily accessible source for investigating common gynecological conditions. In the present study, we aim to evaluate the expression levels of menstrual blood aromatase, SF-1, and HSD17B2 from women with and without endometriosis and their diagnostic performance.
