The impact of this procedure on ovarian reserve can be measured using antral follicle count (AFC) and serum anti-Mullerian hormone (AMH) levels. We aimed to comprehensively evaluate the triple-step procedure for endometrioma and its effect on ovarian reserve in patients with large endometriomas at Bali Royal Hospital (BROS), Denpasar.Methods: This study used a retrospective design and secondary data. The study population included all patients diagnosed with bilateral large endometriomas on transvaginal ultrasonography during a 3-year study period. A large endometrioma is an endometrial cyst measuring > 4 cm in diameter. AMH and AFC are measured before aspiration and three months after cystectomy. The collected data were processed using SPSS v.23.Results: Most patients were aged < 35 years (n = 14; 73.7%). Based on infertility status, almost all patients had primary infertility (17 patients; 89.5%) with a duration of < 5 years (11 patients; 57.9%). Regarding preoperative AFC parameters, the minimum and maximum AFC values were 3.00 and 9.00, respectively, with a mean of 5.57 (1.952). After surgery, the minimum and maximum AFC values were 5.00 and 14.00, respectively, with a mean of 8.47 (2.412). The mean AMH levels before surgery were 2.95 ng/mL (2.027) and 2.83 ng/mL (1.611) after surgery, respectively. A significant difference was found in the AFC values between pre-surgery and post-surgery groups (p< 0.001). However, no significant difference in AMH values was found between the groups.Conclusion: The triple-step procedure may conserve ovarian reserve in large bilateral endometriomas.Keywords: AFC, AMH, large endometrioma, triple-step procedures
