[Effect of acupuncture intervention at different time points on the pregnancy rate of frozen embryo transfer].

OBJECTIVE

To observe the difference in the efficacy of acupuncture intervention at different time points on the pregnancy rate of in vitro fertilization-frozen embryo transfer (IVF-FET).

METHODS

Ninety-nine patients with secondary infertility who were going to receive IVF-FET were divided into a transplantation-day acupuncture group, a transplantation cycle acupuncture group, and a non-acupuncture group according to their wishes, with 33 cases in each group. All three groups of patients received conventional IVF-FET treatment. The transplantation-day acupuncture group received acupuncture treatment 1 h before and 30 min after the embryo transfer, and the transplantation cycle acupuncture group received acupuncture treatment 5 weeks before the FET (once a week, 5 times) and on the day of transplantation, Zigong (EX-CA 1), Guanyuan (CV 4), Taichong (LR 3), Hegu (LI 4), etc. were selected in the two groups. The biochemical pregnancy rate and clinical pregnancy rate in the three groups were compared.

RESULTS

The biochemical pregnancy rate and clinical pregnancy rate in the transplantation cycle acupuncture group were higher than those in the non-acupuncture group (<0.05). There was no statistical difference in the biochemical pregnancy rate and clinical pregnancy rate between the transplantation cycle acupuncture group and the transplantation-day acupuncture group, and between the transplantation-day acupuncture group and the non-acupuncture group (>0.05).

CONCLUSION

Acupuncture during the transplantation cycle can effectively improve the pregnancy rate of secondary infertility patients receiving IVF-FET.
