“…The prospective randomised study by Kontovradis [9] studied embryo transfers in 115 women after proximal tubal occlusion by laparoscopy, or salpingectomy, or expectant management. The rates of implantation and clinical pregnancy were similar for the non-expectant techniques and relatively similar to ours (implantation rate of 19.5% for laparoscopic proximal occlusion, 24.8% for salpingectomy, and 29.3% for Essure 1 ; the clinical pregnancy rates were, respectively 44.4, 55.3, and 40.7%).…”
