aOne started cycle of IVF vs. one started cycle of IUI. bExcluded 6 cycles in the IUI group (cancelled IUI) and 3 cycles in the IVF groups (cancelled the oocyte retrieval). cTwo IUI cycles vs. one oocyte retrieval cycle (Excluded 81 IUI cycles that had ≤1 cycle without live birth. For IUI patients with ≥3 cycles of IUI, only the CLBR of the first two cycles were calculated. Exclude 3 IVF cycles that cancelled the oocyte retrieval). d2 IUI cycles vs. 1 embryo transfer cycle (Excluded 81 IUI cycles that had ≤1 cycle and no live birth. For IUI patients with ≥3 cycles of IUI, only the cumulative live birth of the first two cycles were calculated. Only the 63 fresh ET and 51 frozen ET were included in the IVF groups).
