Brief summary: In the early stage, the preliminary study found that traditional Chinese medicine (TCM) intervention aimed at Nourishing kidney and regulating blood circulation in freeze-all IVF cycles can improve the clinical pregnancy rate. In order to further study the role of TCM in improving the pregnancy outcome of IVF-ET in infertility. A randomized controlled clinical trial will be used in this study. 90 infertile patients are randomly divided into two groups. The control group will be treated with conventional modern medicine, and the treatment group will be treated with traditional Chinese herbs on the basis of conventional modern medicine. The intervention starts from the 5th day of the menstrual cycle and lasts until the day before IVF-ET. After the transplantation, the TCM treatment continues for 14 days. The number of oocytes, antral follicles, AMH, serum FSH, and clinical pregnancy rate will be observed to evaluate the effect of TCM herbs on the improvement of pregnancy outcomes. In addition, all the participants will be asked to complete the self-evaluation of the anxiety/depression scale on the 7th day of the menstrual cycle, before and after transplantation, to analyze the emotional changes of the subjects during the study. The study will also observe the safety and health economic indicators of TCM treatment, so as to improve the overall efficacy of TCM Combined Application in assisted reproductive technology in the future.

Detailed description: The trial is designed as a randomized, controlled clinical trial with two groups established by 1:1 equal allocation, a treatment group with interventions using herbs to tonify the kidneys and regulate blood and a control group treated using conventional Western medicine. Random numbers will be prepared by an independent third-party statistician who prepared a list of random group codes for this study. Enrolled subjects will be given a subject number during the screening process and, upon formal enrolment, will be randomly assigned to either the test or control group with a corresponding random number.

Interventions Treatment method Phase 1: The control group will be treated with conventional Western medicine, whereas the treatment group will receive treatment with the Chinese herbal formula. Treatment with the Chinese herbal formula will start on the 5th day of menstruation cycle. The medicines used will be Er Zhi Wan combined with Si Wu Tang (Radix et Rhizoma Ligustrum 15 g, Radix Morindae Sinensis 12 g, Fructus Lycii 15 g, Semen Cuscutae 20 g, Radix Rehmanniae 15 g, Radix Angelicae Sinensis 10 g, Radix Paeoniae Alba 10 g, Ligusticum wallichii 6 g, Poria cocos 15g,Polygonatum 15g,eclipta 10g); which will be taken for 10-15days.

Phase 2: After ET, the control group will be treated conventionally with no TCM intervention, and the treatment group will continue to take Chinese herbal medicine, changing to Shou Tai pills ( Morinda officinalis 15 g, Teasel 15g，Cuscutae 20 g, Eucommia ulmoides 15 g, Rehmannia 15 g, Cornus officinalis 15 g, loranthus parasiticus 20 g, Ligustrum lucidum 15g, Salvia miltiorrhiza 10g, Scutellaria baicalensis 10g, Atractylodes macrocephala 15g); which will be taken for 14days. The hospital will be responsible for the decoction of 200 mL per dose, 1 dose per day, divided into 2 doses in the morning and in the evening.

Serum human chorionic gonadotropin (hCG) will be measured, and an hCG\>30 IU will be considered to indicate biochemical pregnancy. Ultrasound monitoring will be performed 30 days after ET to calculate the clinical pregnancy rate.
