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 female Syrian hamsters, oxytocin-immunoreactive cell bodies and fibers were found in several preoptic regions, including the medial preoptic area, medial preoptic nucleus and bed nucleus of the stria terminalis.

    In plain wordsIn female hamsters, the body's own oxytocin was found in nerve cells and fibers in several parts of the preoptic area of the brain.

    Summary · context
    Immunocytochemical analysis with OXT-specific antibodies was used to identify the distribution of OXT-containing cell bodies and fibers in female hamster brain and to determine the possible sources of OXT important for sexual receptivity.

    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 female Syrian hamsters, large numbers of oxytocin cell bodies and fibers were located in the paraventricular and supraoptic nuclei and in the anterior hypothalamus.

    In plain wordsIn female hamsters, many cells with the body's own oxytocin sat in two brain nuclei and in the anterior hypothalamus.
