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 heifers with a PGFM pulse induced by estradiol-17β, natural oxytocin increased, beginning 15 min before the nadir that began the PGFM pulse.

    In plain wordsIn heifers, the animals' own oxytocin rose about 15 minutes before a prostaglandin metabolite pulse began.

    Summary · context
    A pulse of a PGF2α metabolite (PGFM) was induced by treatment with 0.1 mg of estradiol-17β on Day 15 (Day 0=ovulation; n=9 heifers).
    Summary · context
    Blood samples were taken every 15 min for 9h beginning at treatment (Hour 0).
