Cumulative live birth rate results after the first, second, and third FE-SET. (A) LBR was analyzed in women (n = 4429) with up to 3 consecutive FE-SETs. Of those who failed to achieve LB after the 1st FE-SET (n = 1335), 885 (56.8%) underwent a 2nd FE-SET. Of those who failed to achieve LB after the 2nd FE- SET (n = 404), 170 (42.7%) patients underwent a 3rd FE-SET. (B) Live birth rates after 1st, 2nd, and 3rd cycles. The number of transfers is shown at the bottom of each bar (Tukey’s range test = * p = 0.01, ** p < 0.001). (C) The cumulative LBR after up to 3 consecutive FE-SET was 92.6% (95% CI: 91.2%–93.9%) as illustrated by Kaplan-Meier estimates reporting also cumulative LBR after the 1st (64.8%; 95% CI: 63.4%–66.2%), and after the 2nd (83.9%; 95% CI: 82.6%–89.0%) FE-SET respectively. The number of transfers is shown at the bottom bar.
