 note = {Purpose: The aim of this retrospective study was to determine whether laparoscopy is necessary in patients with infertility showing bilateral tubal patency on hysterosalpingography (HSG). Methods: One hundred and eight women <40 years of age underwent 4-6 cycles of timed intercourse or intrauterine insemination (IUI) following confirmation of bilateral tubal patency on HSG. Thereafter, 84 women underwent laparoscopy and further cycles of timed intercourse or IUI (laparoscopy group). The remaining 24 women underwent in vitro fertilization-embryo transfer (IVF-ET) without laparoscopy (IVF group). Results: Multivariate analysis showed that infertility of >5 years duration was the only independent factor contributing to the reduced pregnancy rate in the laparoscopy group (HR, 0.64; 95% confidence interval (CI), 0.40- 0.96). The cumulative live birth rates were 75.9% for the IVF group and 62.2% for the laparoscopy group (P=0.03). Conclusions: In women with bilateral tubal patency observed on HSG, laparoscopy may be omitted if IVF-ET is the subsequent treatment of choice, particularly in women with infertility of >5 years duration, 論文},
