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 male Wistar rats bred for low versus high behavioral performance, brain regional oxytocin concentrations did not differ between the lines.

    In plain wordsIn rats bred for different behavioral performance, the body's own oxytocin levels in the brain did not differ between the two lines.

    Summary
    In contrast, no significant differences between the lines were detected with respect to OXT concentrations.

    Summary · context
    In male breeders sampled during selection of the two lines (Wis/HBP: n = 17; Wis/LBP: n = 21), both arginine vasopressin (AVP) and oxytocin (OXT) contents were measured by radioimmunoassay in the motor cortex, septum/striatum, hippocampus, hypothalamus, medulla oblongata and posterior pituitary.

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