• To investigate the correlation of the fertilization strategy and embryo transfer (ET) time with the incidence of ectopic pregnancy. We selected 3,331 fresh and 2,706 frozen-thawed ET cycles for the patients undergoing in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). The fresh transfers included 2 546 IVF-ET and 785 ICSI-ET cycles and 2,220 day-3 embryo and 1,111 day-5 blastocyst transfers, while the frozen-thawed transfers included 2,080 IVF-ET and 626 ICSI-ET cycles and 741 day-3 embryo and 1 965 day-5 or -6 blastocyst transfers. We compared the incidence rate of ectopic pregnancy associated with different fertilization strategies and ET time. The incidence rate of ectopic pregnancy was 1. 41% (36/2 546) in the IVF-ET cycles and 3.44% (27/785) in the ICSI-ET cycles of the fresh transfers, significantly lower in the IVF-ET than in the ICSI-ET cycles (P < 0.01), and it was 1.01% (21/2,080) in the IVF-ET cycles and 0.80% (5/626) in the ICSI-ET cycles of the frozen-thawed transfers, with
