Abstract: 【Objective】 To evaluate the presence of endometriomas on ovarian reserve as assessed by serum anti-Müllerian hormone (AMH) through compared with other benign ovarian cysts and infertility. Also

the related factors were also analyzed. 【Methods】 From June 2013-January 2014

we prospectively accumulated 40 women with endometriomas

22 women with other benign ovarian cysts and 36 infertilities. Serum AMH level were determined preoperatively and compared. Also

correlation analyses were undertaken in order to identify determinants of related factors to ovarian reserve. 【Results】 Compared with controls at baseline

women with endometriomas (1.53 ± 1.37 ng/mL) had lower AMH levels while the difference between other benign ovarian cysts (2.20 ± 1.23 ng/mL) and infertilities (2.82 ± 1.74 ng/mL) was not significant. There was a negative correlation between serum AMH and age in endometrioma group

r = -0.54. BMI

cyst size

bilaterality was not correlated with serum AMH level. 【Conclusion】 The presence of endometriomas per se was associated with a decrease in serum AMH but not the other benign ovarian cysts. Bilaterality of the endometrioma cyst

endometrioma size was not correlated with serum AMH level. But AMH was negatively correlated with age.
