Korean medicine combined with IVF: ① pre-IVF (3 months): improves egg quality, endometrium thickening, ② during stimulation: light supportive herbs, ③ embryo transfer day: acupuncture proven to enhance implantation, ④ early pregnancy: stability herbs (CV4 Guanyuan, etc.). Studies show acupuncture alone improves IVF rates by 10–15%; herbal combination 20–30%. Avoid heavy blood-moving herbs during egg retrieval/transfer. Coordinate with fertility clinic team.
