From: A 3–4 h oocyte retrieval-ICSI interval optimizes clinical outcomes for women over 40 years
Fertilization rates with different OPU-ICSI interval cut-off points: (a) 2 h; (b) 3 h; (c) 4 h. Clinical pregnancy rates with different OPU-ICSI interval cut-off points: (d) 2 h; (e) 3 h; (f). 4 h. P value less than 0.05 was defined as statistical significance.
