 Endometriosis is a common gynecological condition that affects women's reproductive health. In this study, researchers compared the metabolite levels in the follicular fluid of infertile patients with endometriosis to those of control subjects. They found that there were significant differences in the levels of certain metabolites, which could be used as biomarkers for diagnosing endometriosis. Additionally, they identified several metabolic pathways that are affected by endometriosis, including phenylalanine, tyrosine and tryptophen biosynthesis, aminoacyl tRNA biosynthesis, phenylalanine metabolism, and pyrimidine metabolism. The results of this study suggest that metabolic profiling may be useful for identifying biomarkers for endometriosis and providing insight into its underlying mechanisms.
