Electrical activity in 25 isolated human oviducts on different days of the menstrual cycle was recorded with six simultaneous suction electrodes in at least 18 locations. During the follicular phase, electrical activity consisted of a smooth, single slow spike that lasted 3 to 6 seconds, and on which was superimposed a fast spike(s) in the ampulla immediately after menstruation. The shape of this activity changed at midcycle, first in the ampulla and later in the isthmus, to a burst of potentials; in the ampulla it sometimes changed to a slow wave on which was superimposed a series of fast spikes. The pacemakers were stable and their number few. The electrical activity spread with a velocity of 1 to 3 mm/sec. The probability of spread toward the uterus varied with the location in the oviduct and with the day of the cycle. After menstruation, electrical activity spread in the uterine direction. On cycle day 12, activity spread toward the ampullary-isthmic junction (AIJ) from both ends of the oviduct. On days 14 and 15, it spread a short distance from the ampulla to the isthmus, through the AIJ. On cycle day 18, spread toward the uterus covered the uterine half of the ampulla. AIJ, and the isthmus. Two to 5 days later, no constant features could be detected in the spread. These findings suggest that the human oviduct functions like the oviducts of other mammalian species, with the spread of electrical activity and the transport of ova being related.
在月经周期的不同日子，用六个同步吸引电极在至少18个位置记录了25条离体的人输卵管的电活动。在卵泡期，电活动由一个持续3至6秒的平滑单慢峰组成，月经刚结束后壶腹部会叠加一个快峰。这种活动的形态在月经周期中期发生变化，首先在壶腹部，随后在峡部，变为一阵电位；在壶腹部，它有时会变为一个慢波，并叠加一系列快峰。起搏点稳定且数量较少。电活动以1至3毫米/秒的速度传播。向子宫传播的概率随输卵管中的位置和月经周期的日子而变化。月经后，电活动向子宫方向传播。在月经周期第12天，活动从输卵管两端向壶腹 - 峡部连接点（AIJ）传播。在第14天和15天，它从壶腹部向峡部传播一小段距离，经过AIJ。在月经周期第18天，向子宫的传播覆盖了壶腹部的子宫半侧、AIJ和峡部。两到五天后，在传播中未检测到恒定特征。这些发现表明，人类输卵管的功能与其他哺乳动物的输卵管类似，电活动的传播与卵子的运输有关。
