Abstract

Spontaneous isometric contractions of the human fallopian tube were measured in vitro. The tubes were obtained during the follicular phase of the menstrual cycle in 16 experiments and during the luteal phase in 23 experiments. The area under the curve and the frequency of spontaneous isometric contractions, together with the amount of prostaglandins E and F produced by the tube, were measured. Using each tissue as its own control, the effects of adding indomethacin or papeverine to the tissue both were assessed. Indomethacin, a prostaglandin synthetase inhibitor, significantly reduced the prostaglandin output without affecting the tubal motility. By contrast, papaverine, which is a smooth muscle relaxant but not an inhibitor of prostaglandin synthesis, significantly reduced both motility and prostaglandin output. It is concluded that prostaglandins do not have a direct role in the regulation of the spontaneous motility of the human fallopian tube.
