Electrical activity was recorded in 18 morphologically normal human oviducts excised from 17 women during hysterectomy. All women were in the first five years after menopause. The first part of the oviduct to become inactive after menopause was the isthmus near the uterus or the ampullary-isthmic junction. The region which exhibited electrical activity last was the ovarian end of the tube. The typical wave-form of electrical activity in post-menopausal oviducts resembled that recorded during the follicular phase in fertile women: a single smooth wave lasting 3-5s. In three cases, over a bulbous swelling of the ampulla, this typical activity was replaced in continuous, high frequency activity. A hypothesis is provided that the observed changes in electrical activity may be related to certain clinical phenomena such as the increased incidence of tubal pregnancy in the pre-menopause.
在子宫切除术中从17名女性身上切除的18条形态正常的人输卵管中记录了电活动。所有女性均处于绝经后的前五年。绝经后最先失去活性的输卵管部分是靠近子宫的峡部或壶腹-峡部交界处。最后表现出电活动的区域是输卵管的卵巢端。绝经后输卵管中典型的电活动波形类似于在育龄女性卵泡期记录到的波形：单个平滑波持续3 - 5秒。在三例中，在壶腹的球茎状肿胀处，这种典型活动被持续的高频活动所取代。提出了一个假设，即观察到的电活动变化可能与某些临床现象有关，如绝经前输卵管妊娠发生率增加。
