Abstract Objective: To study the pregnancy rate and affecting factors of infertile women due to tubal obstruction treating with fallopian tube recanalization(FTR). Methods: Totally 68 qualified infertile women were included. After collecting their clinical information, we evaluated the pregnancy rate and analyzed the affecting factors with chi-square test, Fisher’s exact test and Logistics regression analysis. Results: The pregnancy rate was 60.29%, and the age, the type of infertility, pelvic operation history, the duration of infertility, unilateral or bilateral tubal obstruction, the shape of fallopian tube after dilation as well as the contrast agent diffusion in pelvic cavity affected the pregnancy rate insignificantly(P>0.05). Nevertheless, among women aged <35 years at the time of FTR, single variable analysis implied that the type of infertility was associated with successful pregnancy(P<0.05); In addition, the type of infertility and the even or uneven diffusion of contrast agent in pelvic cavity were the two independent risk factors of successful pregnancy according to Logistics regression analysis(b=2.410 and 1.876 respectively, P<0.05). However, none of the studied variables was significantly associated with pregnancy among women aged ≥35 years(P>0.05). Conclusion: FTR is an effective treatment with high pregnancy rate for infertile women suffering from fallopian tubal obstruction. Women aged <35 years were recommended with spontaneous pregnancy without technical assistance after FTR, and the primary infertility and the uneven-diffusion of contrast agent in pelvic cavity are the two independent risk factors. The pregnancy rate among women aged ≥35 years is so low that assistant reproductive technology is recommended after FTR.
