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 human and baboon corpus luteum, a sensitive PCR-based assay detected oxytocin gene mRNA.

    In plain wordsIn human and baboon ovary tissue, a very sensitive test found the body's own oxytocin gene was switched on.

    Summary
    Only a highly sensitive assay based on a modification of the polymerase chain reaction succeeded in detecting mRNA copies of the oxytocin gene in both human and baboon corpus luteum.

    Summary · context
    A variety of molecular techniques were used to search human and baboon gonadal tissues for evidence of transcription of the genes for the peptide hormones oxytocin and vasopressin.

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