Abstract Objective: To evaluate the changes of the endometrial contractility during the menstrual cycle in patients with infertility. Methods: Real-time transvaginal ultrasound and advanced audio-visual and computer technology were used to evaluate the endometrial contraction throughout menstrual cycles in 84 patients with infertility. Movement type, frequency and speed were evaluated. Results: The percentage of scans with endometrial movements and non-movement and obscurity was 82.74%, 15.18%, 2.08% in the 336 examinations of 84 patients. The detection rate of endometrial movements was increased during the menstrual cycle(P＜0.05). Seven activity patterns were distinguished, which varied throughout the cycle(P＜0.05). The frequency and speed of the endometrial movement were increased during the follicular phase and decreased after ovulation(P＜0.05). Conclusions: Transvaginal ultrasound and advanced audio-visual and computer technology is effective and practicable in evaluation the endometrial movement. The movement of endometrial varied in accordance with the menstrual cycle.
