Comparison of pregnancy outcomes of high-quality blastocysts formed by transplanting D3 embryos with different developmental rates in patients undergoing cesarean section
Objective To explore the impact of the developmental rate of the third day(D3)embryo in patients undergoing cesarean section on the pregnancy outcomes after high-quality blastocyst transplantation.Methods Clinical data of 107 cycles of cesarean section patients who underwent freeze-thaw high-quality blastocyst transplantation at the Reproductive Medicine Center of our hospital were collected.According to the number of blastomeres in D3 embryos,they were divided into a normal development group(63 cycles)and a rapid development group(44 cycles),and the pregnancy outcomes of the two groups were compared.Results The biochemical pregnancy rate and clinical pregnancy rate in the normal development group were higher than those in the rapid development group(P＜0.05);There was no statistically significant difference in the rates of ectopic pregnancy,miscarriage,preterm birth,and live birth between the two groups(P＞0.05).Conclusion High quality blastocysts derived from D3 embryos with normal developmental rates have higher biochemical and clinical pregnancy rates than those derived from rapidly developing D3 embryos.Patients undergoing cesarean section can prioritize the transfer of high-quality blastocysts derived from D3 embryos with normal developmental rates.
