Characteristics of uterine peristalsis in spontaneous and induced cycles.
OBJECTIVE
To characterize the dynamics of the intrauterine fluid-wall interface (IUFWI) from in vivo transvaginal ultrasound images by new techniques of image processing of sagittal cross-sections of the uterus, in healthy women with normal cycles and patients treated with clomiphen citrate (CC).


METHODS
Clinical study.


METHODS
An ultrasound unit in a large university-affiliated municipal hospital.


METHODS
Twenty-five patients with normal spontaneous cycles (group A) and nine patients treated by CC (group B).


METHODS
Transvaginal ultrasound examinations.


METHODS
Transvaginal ultrasound images were processed to carry out a computational analysis of the resultant IUFWI.


RESULTS
The amplitude and the width of the IUFWI were higher in group B, but the ratio of these measurements was similar in both groups. The frequency of wall motility of group A was lower and its pattern was more symmetrical than that of group B.


CONCLUSIONS
The differences in the dynamic characteristics of spontaneous and CC-induced cycles may constitute an additional parameter that should be considered in embryo transport.
