Figure 4. Proportion of patients ≥41 years with ≥2 embryos on day 3 and day 5 according to trigger typePercentages of women achieving ≥2 embryos on day 3 (panel A) and ≥2 embryos on day 5 (panel B) are shown for the ≥41 years subgroup, comparing Double trigger versus r-hCG. The proportion of cycles achieving ≥2 day-3 embryos was higher with the modified double trigger (13/15 cycles, 86.7%) compared with r-hCG alone (7/13 cycles, 53.8%). Achievement of ≥2 day-5 embryos occurred in 5/15 cycles (33.3%) with the modified double trigger and in 0/13 cycles (0%) with r-hCG alone. Comparisons were performed using Fisher’s exact test.
