We did not find a significant difference in serum AMH levels according to the presence of endometriosis [endometriosis 2.90 ± 2.21 (mean ± SD) ng/mL vs. control 3.17 ± 2.93 ng/mL, P = 0.29 (Figure 3A)]; however, AMH levels in PF were significantly lower in women with endometriosis compared to those of control women [endometriosis 2.08 ± 2.06 (mean ± SD) vs. control 4.40 ± 4.77 ng/mL, P = 0.0002 (Figure 3B)]. The gene discussed is AMH; the disease is endometriosis.
