In young women aged 18–22 years, we observed significantly lower median AMH levels in patients with bilateral ovarian endometriomas compared to the controls (0.82; IQR: 1.12 vs. 4.63; IQR: 1.09; p < 0.001) and between patients with bilateral ovarian endometriosis and unilateral ovarian endometriosis (0.82; IQR: 1.12 vs. 4.24; IQR: 1.24; p = 0.036), while differences were not observed between unilateral ovarian endometriosis patients and the controls (4.24; IQR: 1.12 vs. 4.63; IQR: 1.09; p < 0.001; Fig. 3). Here, AMH is linked to ovarian endometriosis.
