将少量印度墨水注入峡部最低区域后，检查仓鼠输卵管体内的运动。在排卵前不久、排卵期间和排卵后几小时内观察到峡部和壶腹的活跃和协调运动，导致墨水快速输送到上壶腹（并最终到达卵巢囊）。在发情周期的其余时间里，尽管峡部有活跃的收缩运动，但没有墨水被输送到上壶腹。输卵管作为一个整体显然表现出仅在排卵期期间适合精子运输的有效收缩运动。
The movement of the hamster oviduct in vivo was examined after injection of a small quantity of India ink into the lowermost region of the isthmus. An active and co-ordinated movement of both the isthmus and ampulla that caused a rapid transport of the ink to the upper ampulla (and eventually to the ovarian bursa) was observed shortly before, during and within a few hours after ovulation. During the rest of the estrus cycle, no ink was transported to the upper ampulla despite active contractile movement by the isthums. The oviduct as a whole evidently exhibits an efficient contractile movement suited for sperm transport only during the periovulatory period.
