Objective:To observe the clinical efficacy of transcutaneous electrical acupoint stimulation (TEAS) sequential therapy on infertile patients undergoing in vitro fertilization-embryo transfer. MethodsEighty-three patients were randomly divided into the treatment group (42 cases) and control group (41 cases). The control group was treated with promotion program of western medicine antagonist, and the treatment group was treated with promotion program of western medicine antagonist plus TEAS sequential therapy. After the regular cycle of antagonist promotion regimen, the changes on dose of promoting drugs, intervention time of promoting drugs, embryo development related indicators (ovum fertilization rate, cleavage rate and excellent embryo rate), pregnancy related indicators (biochemical pregnancy rate, clinical pregnancy rate and embryo implantation rate) were compared.  Results:①Finally, 80 patients including 40 patients in the treatment group and 40 patients in the control group completed the trial. There were 15 patients in the treatment group and 14 patients in the control group who met the condition of fresh embryo transfer. ②During the course of treatment, the dosage of promoting drugs in the treatment group was significantly less than that in the control group (P<0.05). There was no statistically significant difference on the intervention time of promoting drugs between the two groups (P>0.05). ③During the course of treatment, the rate of excellent embryos in the treatment group was significantly higher than that in the control group (P<0.05). There were no statistically significant differences on the ovum fertilization rate and cleavage rate between the two groups (P>0.05). ④During the follow-up, the biochemical pregnancy rate, clinical pregnancy rate and embryo implantation rate in the treatment group were higher than those in the control group, but with no statistically significant differences (P>0.05).  Conclusion:The efficacy of TEAS sequential therapy combined with western medicine antagonist promotion program on the infertile patients undergoing IVF-ET is better than western medicine alone, especially in reducing the dosage of promoting drugs and improving the rate of excellent embryos.
