Clinical Observation of Ultrasound-guided Embryo Transfer after In Vitro Fertilization

[Objective] To investigate the effect of transabdominal ultrasound-guided embryo transfer on the outcome of in vitro fertilization-embryo transfer (IVF-ET). [Methods] The data of 461 patients undergoing IVF-ET (including intracytoplasmic sperm injection) therapy for 521 cycles in our Reproductive Medicine Center were analyzed retrospectively. The patients were divided into two groups: the traditional group (group A) and the ultrasound-guided group (group B), including 187 cycles and 334 cycles, respectively. The clinical pregnancy rate, implantation rate, embryo retention rate, and ectopic pregnancy rate between two groups were compared. [Results] The clinical pregnancy rates of group A and group B were 35.8% (67/187) and 38.3% (128/334), P 0.05; the implantation rates were 17.4% (104/599) and 23.2% (179/773), P 0.01; the embryo retention rates were 3.7% (7/187) and 0.3% (1/334), P 0.01; the ectopic pregnancy rates were 3.0% (2/67) and 1.6%(2/128), P 0.05.[Conclusion]Transabdominal ultrasound-guided ET can increase the implantation rate and decrease the embryo retention rate, may be helpful to improve the clinical pregnancy rate and decrease the ectopic pregnancy rate, so it is an effective technique for embryo transfer.
