Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In women with uterine fibroids, the body's own oxytocin-positive nerve fibres in the myoma pseudocapsule were substantially higher in the isthmian-cervical region than in the fundal and corporal regions.

    In plain wordsIn women with fibroids, natural oxytocin nerve fibres were far more common near the cervix than in the upper uterus.

    Summary
    A comparatively lower number of OXT-positive nerve fibers were found in the fundal MP (6.3 ± 0.8 CU). OXT-positive nerve fibers with OXT were marginally increased in corporal MP (15.0 ± 1.4 CU) and were substantially higher in the isthmian-cervical region MP (72.1 ± 5.1 CU) (p < 0.01).

    Summary · context
    We investigated the distribution of the opioid neuropeptides, as enkephalin (ENK) and oxytocin (OXT), in the nerve fibers within MP and their possible influence in human reproduction in 57 women.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.
