Abstract To explore the correlation between periovary enhancement characteristic of transvaginal fallopian ultrasound contrast of the patients and their natural pregnancy outcomes, and to study its value for evaluating the function of fimbriated extremity of fallopian. Methods: 136 patients with primary or secondary infertility were selected and were given transvaginal hysterosalpinx ultrasonography (HyCoSy) from January 2018 to December 2019. The dispersion characteristics of contrast agents at the end of the fallopian around the ovary of the patients were observed, and the dispersion characteristics were divided into I, II, III and IV levels. Then the space between fimbriated extremity of fallopian and ovary was measured. Ovulation monitoring of the patients was conducted and their pregnancy outcomes were followed up from the 2nd month after HyCoSy. Results: There were 24 cases with grade 0 periovarian contrast enhancement, and the distance between fimbriated extremity of fallopian and ovary was 7.07±0.76mm, among them, 2 patients (3.3%) were succeeded natural pregnancy and 22 patients (96.7%) were failed natural pregnancy. There were 33 patients with grade I enhanced by periovarian contrast agent, and the distance between fimbriated extremity of fallopian and ovary was 5.57±0.36mm, among them, 6 patients (18.2%) were succeeded natural pregnancy and 27 patients (81.8%) were failed natural pregnancy. There were 31 patients with grade II enhanced by periovarian contrast agent, and the space between the fimbriated extremity of fallopian and ovary was 3.98±0.18mm, among them, 13 patients (41.9%) were succeeded natural pregnancy and 18 patients (58.1%) were failed natural pregnancy. There were 48 patients with grade III enhanced by contrast agent around the ovary, and the space between the fimbriated extremity of fallopian and ovary was 3.07±0.13mm, among them, 31 (64.6%) were succeeded natural pregnancy and 17 (35.4%) were failed natural pregnancy. The space between the fimbriated extremity of fallopian and ovary had shortened as the increase of grade of the enhanced by contrast agent around the ovary (P=0.000), but the success rate of natural pregnancy had increased (P=0.006). Conclusion: The function of fimbriated extremity of the fallopian and the space between the fimbriated extremity of the fallopian and the ovary maybe influence the enhancement characteristics of the fallopian ultrasound contrast agent around the ovary. The more severe the fimbriated extremity of fallopian is attached, the farther the relative space between the fimbriated extremity of fallopian and the ovary, the less the enhancement of the fallopian ultrasound contrast agent around the ovary, and the lower the success rate of natural pregnancy.
