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.

    In female California mice, the body's own plasma oxytocin rose after aggression tests, but only under long days.

    Summary
    Females tested in aggression tests also showed a significant increase in plasma oxytocin levels, but only when housed in long days.

    Summary · context
    We examined the stress hormone responses of monogamous California mice (Peromyscus californicus) to resident-intruder tests.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Other

    In female California mice, animals housed under long days had more oxytocin-positive cells in the paraventricular nucleus than animals housed under short days; males showed no such difference.

    In plain wordsIn female California mice, long days brought more of the body's own oxytocin-making cells in one brain area than short days; males did not differ.

    Summary
    This was consistent with our observation that females but not males had more oxytocin positive cells in the paraventricular nucleus (PVN) when housed under long days.
