Results from this study3

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

Natural levels measured3

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. 01AnimalEndogenous levelAnimal study (in vivo)Other

    In sham-lesioned rats, acute immobilization stress raised the body's own plasma oxytocin levels, with a significantly greater response in females than in males.

    In plain wordsIn rats, stress raised the body's own oxytocin in blood, more in females than in males.

    Summary
    In sham-lesioned rats plasma levels of OT were raised following stress, the response being significantly greater in female compared with male animals.

    Summary · context
    We have investigated the role of ascending noradrenergic pathways in the control of oxytocin (OT) and arginine-vasopressin (AVP) secretion during acute immobilization stress in male and female rats.

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

  2. 02AnimalEndogenous levelAnimal study (in vivo)Other

    In male rats, lesions of the ventral noradrenergic bundle markedly elevated the body's own oxytocin response to stress.

    In plain wordsIn male rats, damaging a brain noradrenaline pathway markedly raised the body's own oxytocin response to stress.
