The motor functions of the Fallopian tube classified into types of muscular movements and their correlation to the estrual periods and kinds of sex hormones was studied, as follows:
1. The movements of the tube were itemized into the peristaltic, the conductive segmented, the non-conductive segmented, the pendular, the bending and the torsional movements.
2. Both the circular and the longitudinal tubal muscles showed larger contractility under electric stimulation when estrogen was in predominance than when progesterone was in predominance, but the automatic contraction was smaller in the former state than in the latter.
3. The frequency of the contractions and the pace-maker activity were higher when estrogen was in predominance than when progesterone was in ascendancy.
4. The fatigability of the muscles was lower under predominance of estrogen than under predominance of progesterone.
5. The function of transporting ova lowered in gestation and puerperium, but showed little variation in any other stage.
