目的　通过对育龄期妇女输卵管内部形态的观察和测量，提供输卵管各部位的活体和离体数据，为输卵管生育和节育研究提供科学依据。　方法　输卵管造影100例、宫腔镜检查30例和离体标本20例进行输卵管各部位长度，径线及内口的形态的观察和测量，采用两样本t检验进行分析。　结果　⑴造影观测双侧输卵管内口直径为（1.07±0.48）mm；间质部中段（0.50±0.22）mm；间质部远端（0.32±0.12）　mm；峡部内径（0.46±0.28）mm；壶腹部内径（2.43±1.45）mm；间质部长度（5.27±4.28）mm；峡部长度（24.35±　12.27）mm；壶腹部长度（39.94±22.05）mm；总长（70.78±32.07）mm。⑵宫腔镜观测内口为圆形占76.7%和椭圆形占23.3% ；⑶离体标本观测内口周径（5.87±1.46）mm；峡部周径（2.83±1.87）mm；间质部长度（6.73±　2.49）mm；峡部长度（20.56±7.61）mm；全长（85.42±22.93）mm。　结论　⑴输卵管是内外口扩大而内径不均匀走行曲折迂回的管道，间质部呈漏斗状，最狭窄的部位在间质部远端。⑵了解输卵管的内部形态对生育和节育的研究都具有重要意义。

Objective　To explore morphologic features of the fallopian tube of reproductive aged women and provide the basis for the study of tubal sterilization and fertility.　Methods　The length, diameter and the orifice of the fallopian tube were observed, measured and analyzed on the data from 100 cases of salpingography (HSG), 30 cases of hysteroscopy and 20 cadaveric specimens.　Results　HSG showed that, the diameter of internal orifice，the lengths of the middle and distal of interstitial parts were about （1.07±0.48） mm, （0.50±0.22） mmand （0.32±0.12） mm averagely, respectively. The internal diameter of the isthmus and the ampulla were (0.46±0.28 mm) and (2.43±1.45) mm respectively. the length of interstitial part, isthmus, ampulla and the total were (5.27±4.28 mm), (24.35±12.27) mm，(39.94±22.05)mm and (70.78±32.07) mm respectively. Hysteroscopy showed the round(76.7%) or oval（23.3%）internal orifices of fallopian tube. The perimeter of internal orifice was (5.87±1.46)mm, and of the isthmus (2.83±1.87) mm. The length of interstitial part, isthmus and the total were (6.73±2.49) mm, (20.56±7.61) mm and (85.42±22.93) mm, respectively on cadaveric specimens.    Conclusions    Fallopian tube is a tortuous channel with the dilated internal and external orifices. The interstitial part is funnel-shaped, with the narrowest part at the distal of it. It is necessary to understand morphologic features of fallopian tube for the study of sterilization and fertility.
