Effect of Fire-Needle Combined With Regular Acupuncture on Pregnancy Outcome in Patients With Recurrent Implantation Failure Undergoing In Vitro Fertilization

March 8, 2026 updated by: Cui Hong Zheng, Huazhong University of Science and Technology

This study aims to evaluate whether fire-needle combined with regular acupuncture improves pregnancy outcomes in patients with recurrent implantation failure (RIF), compared to no or regular acupuncture.

A retrospective cohort study was conducted at a university-affiliated hospital. One hundred RIF patients undergoing embryo transfer between July 2024 and June 2025 were assigned to three groups: a non-acupuncture group, a regular acupuncture group, and a fire needle combination group (receiving both fire needle and regular acupuncture).

Key outcome measures, including the β-hCG positive rate, clinical pregnancy rate (CPR), and miscarriage rate (MR), were compared among the three groups.
