Abstract Objective: Evaluation of the function of female levator ani muscle by using perineal three-dimensional ultrasonography, and to explore the correlation between the level of female estrogen and the levator ani muscle function. Methods: Excluding the influence of fertility factors and endocrine factors, 71 subjects were selected. According to menstrual history and age, the subjects were divided into premenopausal group(n=39) and menopause group(n=32). All subjects were subjected to perineal ultrasonography, and images of the anal sphincter in resting state and in Valsalva state were collected. Measure the levator hiatus anteroposterior diameter, levator hiatus area and length of the levator ani muscle. Calculate the change of levator hiatus anteroposterior diameter(ΔL), the change of levator hiatus area(ΔA), and the strain rate of the levator ani muscle in the Valsalva states. The estrogen levels(E2) of the subjects were measured, and the correlation analysis was made between the ultrasonic measurements and the estrogen levels. Results: Premenopausal group of levator hiatus area during Valsalva maneuver,levator hiatus anteroposterior diameter during Valsalva maneuver, levator ani muscle length during Valsalva maneuver and ΔA were negatively correlated(r=-0.418, -0.367, -0.346, -0.458), the difference was statistically significant(P<0.05). There was no correlation in ΔL, ε and the estrogen level, the difference was not statistically significant(P>0.05). All pelvic floor measurements in the menopause group were not associated with estrogen levels, the difference was not statistically significant(P>0.05). Conclusion: The three-dimensional transperineal ultrasonography can evaluate the function of levator ani muscle. Premenopausal levator ani muscle function decreased with estrogen levels. Postmenopausal estrogen levels have no significant effect on levator ani muscle function.
