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 healthy men, lumbar cerebrospinal fluid oxytocin showed no significant alteration during the sexual response cycle.

    In plain wordsIn healthy men, the body's own oxytocin in spinal fluid did not change significantly during sexual arousal and orgasm.

    Summary
    In contrast, none of the other measures, in particular prolactin and dopamine or its metabolites, reflected significant alteration.

    Summary · context
    However, alterations in dopaminergic or peptidergic activity are not found in lumbar CSF, possibly due to local and restricted release in diencephalic and mesencephalic brain regions.
    Summary · context
    In parallel with peripheral endocrine measures, lumbar CSF was drawn via an indwelling spinal catheter during the sexual response cycle in 10 healthy males and 10 age-matched controls, and analysed for prolactin, oxytocin, biogenic monoamines and/or their metabolites as well as inhibitory and excita…
