Acupuncture thickens the uterine lining during IVF treatment To evaluate the combined effects of acupuncture and Sildenafil on endometrial thickness during IVF. Prospective self-controlled trial. Four infertility patients with prior IVF failures and an inability to achieve a uterine lining of R8 mm. A series of five acupuncture treatments applied at specific intervals during an IVF cycle. All other parameters were kept consistent with the respective patient’s prior cycle. All four subjects achieved endometrial lining thickness of >9mm following the administration of acupuncture, including one patient whose lining did not exceed 5 mm in a previous cycle. We also noted that endometrial thickness of most patients continued to increase post-hCG administration. >p>Our pilot study is consistent with previous reports that acupuncture improves uterine lining measurements over previous cycles.
