Fig 1. Urinary estrogen metabolites levels in control subjects (control) or patients with endometriosis (P-EOSIS).

Fig 1

All subjects were either without hormonal therapy (left panel; control = 4; P-EOSIS = 10) or on hormonal therapy (right panel; control = 5; P-EOSIS = 10) at the time of surgery (DOS) and post-surgery intervention (PSI). Levels of estrogen metabolites were normalized to urinary creatinine. A. 17β-estradiol. B. 16-Keto-17β-Estradiol. C. Estriol. D. 2-Hydroxyestradiol. E. 2-Hydroxyestrone. * indicates significant difference between groups, Mann-Whitney test, P-value <0.05, error bars indicate SEM.
