The impact of different etiologies of diminished ovarian reserve on pregnancy outcome in IVF-ET cycles

Abstract

Background/aim: Diminished ovarian reserve (DOR) represents a major challenge in reproductive medicine, as it is often associatedwith poor ovarian stimulation response, high cycle cancellation rate, and low pregnancy rate. The aim of the present study is to comparethe clinical pregnancy rates in intracytoplasmic sperm injection-embryo transfer (ICSI-ET) cycles in patients with different DORetiologies.Materials and methods: Patient data were recorded with a computer-based program called Success Estimation Using a RankingAlgorithm (SERA). Overall, 459 patients were divided into 3 groups according to their DOR etiologies (Group A: idiopathic, n = 81;Group B: age-related, n = 294; Group C: previous ovarian surgery, n = 84).Results: Out of 459 stimulation cycles, 378 (82.4%) reached the oocyte retrieval stage, while 201 (43.8%) had embryo transfers. Therewas no significant difference between the patients with different DOR etiologies in terms of embryo transfer and cycle cancellation rate.The patients who had embryo transfer were 44 (52.4%) in Group A, 38 (46.9%) in Group B, and 119 (40.5%) in Group C. There were nosignificant differences between the three groups (P = 0.114). The percentages of women who had oocyte retrieval were 84.5% in GroupA, 70% in Group B, and 80.3% in Group C (P = 0.104). While clinical pregnancy per transfer was 35.8% in Group A, 19.8% in Group B,and 29.5% in Group C, there was no statistically significant difference between the groups (P = 0.113).Conclusion: Although ovulation induction and ICSI-ET outcomes, including clinical pregnancy and live birth rates, were notsignificantly different with regards to the etiology of DOR, young women with DOR may benefit from assisted reproductive techniques.
