Key Finding
Acupuncture performed around the time of embryo transfer did not show significant benefit for improving clinical pregnancy rates in women undergoing IVF/ICSI treatment.
Researchers conducted a comprehensive review of 188 studies involving nearly 60,000 women to identify which interventions around the time of embryo transfer might improve pregnancy success rates during IVF or ICSI treatment. The study examined 38 different interventions used within 24 hours before or after embryo transfer. The researchers found that several technical factors significantly improved clinical pregnancy rates: using ultrasound guidance during the transfer procedure (rather than doing it by touch alone), using softer catheters, and applying hyaluronic acid. Some medications also showed promise, including G-CSF, Atosiban, and hCG. Interestingly, bed rest after embryo transfer was associated with lower pregnancy rates and should not be recommended. Regarding acupuncture specifically, this study found that acupuncture performed around the time of embryo transfer did not show a significant benefit for improving pregnancy outcomes in IVF patients. This contrasts with some earlier smaller studies, but this comprehensive review provides stronger evidence by pooling data from multiple trials. For couples undergoing fertility treatment, these findings suggest focusing on proven technical aspects of the transfer procedure itself rather than relying on acupuncture as an add-on intervention during the embryo transfer period. If you are considering acupuncture for fertility support, consult with a licensed acupuncturist certified in reproductive health to discuss evidence-based approaches for other aspects of fertility care.
This comprehensive systematic review and meta-analysis evaluated 188 RCTs (n=59,530) examining 38 interventions performed within 24 hours of embryo transfer during IVF/ICSI cycles. Primary outcome was clinical pregnancy rate confirmed by ultrasound. Interventions demonstrating significant benefit included ultrasound-guided transfer versus clinical touch (RR 1.265, 95% CI 1.151-1.391), hyaluronic acid (RR 1.457, 95% CI 1.197-1.261), and soft versus hard catheters (RR 1.122, 95% CI 1.028-1.224). Pharmacological interventions showing promise included G-CSF (RR 1.774, 95% CI 1.252-2.512), Atosiban (RR 1.493, 95% CI 1.184-1.882), and hCG (RR 1.232, 95% CI 1.099-1.382). Bed rest post-transfer showed reduced pregnancy rates (RR 0.857, 95% CI 0.741-0.991). Notably, acupuncture performed peri-transfer did not demonstrate significant benefit. Most studies showed moderate quality with low risk of bias for randomization (62.8%) and attrition (55.8%), though publication bias was evident. Clinical takeaway: Focus on procedural optimization rather than acupuncture during the peri-transfer period.
