Results from this study4

No result from this study comes from a test of the peptide.

Natural levels measured4

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. 01HumanEndogenous levelNon-randomized trialOther

    In five healthy young women, the baseline level of serum oxytocin increased in all women during treatment with a combined oral contraceptive.

    In plain wordsIn five healthy young women, the body's own oxytocin baseline level rose during oral contraceptive use.

    Summary
    Although the baseline level of oxytocin increased in all women and the average concentration increased in four of the women during treatment, there was no clear-cut effect on the peak frequency.

    Summary · context
    Serum profiles of oxytocin were studied by means of a continuous blood sampling system in five young healthy women before and during treatment with a combined oral contraceptive.
