Objective: The objective of this study was to assess the impact of discordant ovarian antral follicle counts (AFCs) on cycle stimulation and live birth in autologous in vitro fertilization (IVF) cycles. Materials and Methods: This is a retrospective analysis of first-time cycles of 153 patients undergoing gonadotropin-releasing hormone-antagonist IVF. Results: While AFC significantly correlated with cycle stimulation characteristics, only the right ovarian AFC significantly correlated with live birth (r = 0.18, P< 0.02). Right ovarian AFC was significantly greater in live birth cycles (12.3 ± 7.8) compared to cycles without a live birth (9.6 ± 6.0, P< 0.02). Using ≤ 7 as a threshold of low unilateral AFC, concordant low AFC was present in 28% (Group 1: n = 43); discordant low left and normal right in 13% (Group 2: n = 19); discordant low right and normal left in 11% (Group 3: n = 17); and concordant normal in both ovaries in 48% (Group 4: n = 74) of patients. Live birth was similar in Group 2 (36.8%), Group 3 (35.3%), and Group 4 (37.8%), but significantly less in Group 1 (9.3%) (P < 0.05). Conclusion: Live birth was higher with greater right AFC. Using threshold AFC, adverse outcomes were only noted when both ovaries had low counts. Individual AFC may serve as a more specific indicator than total AFC as a marker of ovarian reserve.
