Objective To observe the effect of intracavitary shortwave physiotherapy combined with acupuncture on the endometrial receptivity of in vitro fertilisation and embryo transplantation（IVF-ET）patients and evaluate the treatment outcome.Methods Ninety seven IVF-ET patients were randomized into combined treatment group of 51cases and western medicine group of 46cases.Both groups were given luteal phase long protocol.During the controlled ovarian hyperstimulation

the combined treatment group was given acupuncture combined with intracavitary shortwave physiotherapy after menstruation and lasted to the day of injecting human chorionic gonadotropin（HCG）.The western medicine group was given western medicine treatment only.The endometrial thickness

type and endometrial blood flow resistance index（RI）on the day of injecting HCG and the number of retrieved oocytes

rate of high-quality oocytes

fertilization rate

rate of high-quality embryos and clinical pregnancy rate were observed and compared.Results There was no significant difference in the endometrial thickness between groups（P>0.05）.There was 74.5%（38/51cases）of A-type endometrium in the combined treatment group and 45.7%（21/46cases）in the western medicine group

with significant difference between groups（P<0.01）.The blood flow RI of follicle membrane on the day of injecting HCG in the combined treatment group was significantly lower than that in the western medicine group（P<0.01）.There was no significant difference in the number of retrieved oocytes and the fertilization rate between groups（P>0.05）.The rate of high-quality oocytes

high-quality embryos and clinical pregnancy rate in the combined treatment group were significantly higher than those in the western medicine group（P<0.05）.Conclusion Intracavitary shortwave physiotherapy combined with acupuncture could obviously improve the endometrial receptivity of IVF-ET patients and improve pregnancy rate.
