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.

    Immunoreactive oxytocin was present in 80% of testicular interstitial cells of adult Wistar and Brattleboro rats.

    In plain wordsIn rats, the body's own oxytocin was found in most of the cells between the sperm-forming tubes of the testis.
