Results from this study2

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

Natural levels measured2

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.

  1. 01HumanEndogenous levelObservational studyMechanism

    In women undergoing IVF, tenaculum placement was associated with raised serum oxytocin in four of five patients, lasting to the end of the transfer.

    In plain wordsIn women having IVF, using a tenaculum was linked to a rise in the body's own oxytocin in four of five patients.

    Summary
    When tenaculum placement was used, it was temporally (four out of five patients) associated with an elevation in oxytocin level, which remained elevated until of the end of ET procedure.

    Prospective clinical study of 10 women undergoing in vitro fertilization (IVF) treatment with ET in the Section of Reproductive Medicine and Endocrinology at the Department of Obstetrics and Gynecology, University of Bonn, Germany.
    Summary · context
    Serial blood samples were collected in time intervals of 20 s during embryo transfer procedure and serum oxytocin concentration was measured.

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

  2. 02HumanEndogenous levelObservational studyMechanism

    In women undergoing IVF, none of the embryo transfer procedures without tenaculum placement raised serum oxytocin.

    In plain wordsIn women having IVF, embryo transfer without a tenaculum did not raise the body's own oxytocin in blood.

    Summary
    In the absence of tenaculum placement, none of the procedures associated with ET led to an increase in serum oxytocin concentration.
