Abstract

It has been recognized from experimental or invasive studies that the nonpregnant human uterus has an inherent contractibility. We used vaginosonography for imaging contractions of the inner third of the myometrium. The direction, frequency, and symmetry of contractions were noted. We studied 53 women and subdivided them into four groups based on the cycle phase. During menstruation we found contractions toward the cervix with irregular frequency varying between 1 and 3/min. In the periovulatory period we noted the highest frequency of 10/min of regular contractions toward the fundus. The results showed that active myometrial contractions can be detected sonographically throughout the whole menstrual cycle. Increased myometrial contractions toward the fundus in the periovulatory period may be involved in sperm transport to the tubes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
