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 gilts, genistein given by mouth raised the body's own plasma oxytocin concentration to almost twice that of the control group after artificial insemination.

    In plain wordsIn pigs, genistein raised the body's own oxytocin in blood to almost twice the level of control pigs after insemination.

    Summary
    Oxytocin concentrations were almost twice as high in the G-group as in C-group after the AI.
    3 context sentences
    Summary · context
    Genistein stimulated elevations of plasma oxytocin and prostaglandin E₂ concentrations and a pulsative pattern in prostaglandin F₂(α) concentration.
    Summary · context
    Ten gilts were fed a soya-free diet and fitted with jugular vein catheter through vena auricularis.
    Summary · context
    The gilts were randomly divided into two groups (G- and C-group) where the G-group was given pure genistein, 1 mg/kg body weight (BW) twice daily, per os.

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

AI wrote and checked these results. AI can make mistakes, so check important results against the source.
