Abstract: Objective To explore three-dimensional scanning and reconstruction technology in embryo transfer training. Methods Two sets of female reproductive system models, standard and cervical stenosis, were reconstructed with three-dimensional scanner, data processing software EXScan-Pro and 3D printer. Twenty clinical and laboratory personnel were trained to simulate the transfer of degenerated embryos, and the accuracy of embryo implantation site, the time required for embryo transfer and the frequency of replacing the transfer catheter before and after the training were evaluated. Results After training, the accuracy score of embryo implantation site was increased from 0.60±0.41 to 1.37±0.29 (P＜0.05); the time required for embryo transfer was shortened from (340±146) s to (180±59) s (P＜0.05); the frequency of replacing the transfer catheter was decreased from (0.83±0.37) to (0.23±0.13) times (P＜0.05). Conclusions Application of rebuilding female reproductive system model for embryo transfer training can improve the practical experience of operators prior to formal surgery, improve the stability of embryo transfer and help to establish a standardized operation process, as a supplement to the traditional observation and teaching methods.
