Table 5 Comparison of characteristics of adverse and non-adverse DOR infertile patients classified by serum AMH concentrations at 6 months after laparoscopic cystectomy

From: Evaluation of factors predicting diminished ovarian reserve before and after laparoscopic cystectomy for ovarian endometriomas: a prospective cohort study

  Adverse DOR (n = 9) Non- adverse DOR (n = 26) P value
Age (years) 33 (29–39) 34 (26–39) 0.64
Laterality of cysts
 Unilateral (%) 5 (55.6) 16 (61.5) 0.76
 Bilateral (%) 4 (44.4) 10 (38.5)
Serum AMH concentrations (ng/mL)
 Before surgery 2.5 (1.7–3.4) 3.5 (1.5–10.5) 0.02
 3 months after surgery 0.5 (0.1–2.3) 2.3 (0.4–6.1) <0.001
 6 months after surgery 0.6 (0.1–1.1) 2.1 (1.1–9.1) <0.001
