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 postmortem tissue of men with chronic heart failure, oxytocin neurons showed no statistically significant difference from controls.

    In plain wordsIn men who died of chronic heart failure, the body's own oxytocin in brain tissue did not differ from controls.

    Summary · context
    Here we present a postmortem analysis of vasopressin and oxytocin-immunoreactive neurons and their terminals in the posterior pituitary of 8 male patients (53.8+/-9.3 years) who had died from CHF and 9 male controls (54.6+/-11.8 years).

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