Abstract

The objective was to study the characteristics of ultrasonographically detected subendometrial myometrial contractions. The contractions were evaluated by 328 ultrasound scans throughout the menstrual cycle. Reproducibility of these findings were studied in consecutive cycles. Eighteen healthy ovulatory volunteers with proven fertility were evaluated for at least one complete menstrual cycle in the follicular, periovulatory, and luteal phases. Multiple cycles were studied in 10 volunteers. The results showed that the contractions increase in frequency, amplitude, and percentage toward the fundus throughout the follicular and periovulatory phases. The pattern is essentially reversed in the luteal phase. There is reproducibility of these patterns from cycle to cycle. We conclude that there is a definite identifiable pattern of subendometrial myometrial contractility that varies with the phases of the normal menstrual cycle and recurs in a similar fashion from cycle to cycle.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The non-pregnant uterus is constantly active throughout the reproductive period of life and is subjected to mechanical strain.

    “It became evident that the non-pregnant uterus is constantly active throughout the reproductive period of life and thereby, like other mechanically active organs of the body such as the skeletal and the cardiovascular systems, respectively, rather inevitably subjected to mechanical strain.”

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.
