A total of 92 infertility patients with endometrial thickness &amp;lt;7\u202fmm undergoing AC-FET at our hospital were enrolled and randomly assigned to two groups: the control group (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f45) received oral estradiol valerate-based hormone replacement therapy combined with sham acupuncture; the Intervention Group (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f47) received the same HRT regimen combined with Tiao-Jing-Cu-Yun Acupuncture administered every other day starting from menstrual cycle day 2\u20133 until the day before embryo transfer. The primary outcome measure was the clinical pregnancy rate. Secondary outcomes included the embryo implantation rate, early miscarriage rate, and changes in endometrial parameters assessed via transvaginal ultrasound before and after treatment, including endometrial thickness, volume, pattern classification, subendometrial blood flow grading, and hemodynamic parameters.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Baseline characteristics were comparable between the two groups. After treatment, the Intervention Group showed a significantly greater increase in progesterone (P) level, endometrial thickness and volume, and a more pronounced decrease in endometrial resistance index (RI) and pulsatility index (PI) compared to the control group (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05).
