Peristaltic movements of the endometrium were evaluated by serial transvaginal ultrasound throughout 21 spontaneous menstrual cycles, 15 oral contraceptives (OCs) cycles, and 18 in vitro fertilization (IVF) cycles. A score of 0, 1, or 2 was assigned for absent, mild, or strong movements. An average score of 1.5 was obtained at midcycle in spontaneously ovulating women, which was significantly different from early or late follicular (0.36 and 0.5) or luteal (0.4) phase scores. Significant differences were found among the three groups: IVF patients averaged more movements than natural cycle patients, who in turn had a higher incidence than patients taking OCs. Increased peristaltic endometrial movements appear to occur in women around midcycle, probably as an enhancing mechanism for sperm propulsion towards the tubal ostia.
在21个自然月经周期、15个口服避孕药（OC）周期和18个体外受精（IVF）周期中，通过连续经阴道超声评估子宫内膜的蠕动运动。根据运动缺失、轻微或强烈分别给予0、1或2分。自发排卵女性在月经周期中期的平均得分为1.5分，这与卵泡早期（0.36）、卵泡晚期（0.5）或黄体期（0.4）的得分有显著差异。三组之间存在显著差异：IVF患者的平均运动次数多于自然周期患者，而自然周期患者的发生率又高于服用OC的患者。子宫内膜蠕动运动增加似乎发生在月经周期中期左右的女性中，这可能是一种促进精子向输卵管开口推进的机制。
