Results from this study2

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

Studies that did not test the peptide alone2

In this study, Oxytocin was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Oxytocin.

  1. 01AnimalNot a test of Oxytocin aloneAnimal study (in vivo)Mechanism

    In male rats, a vasotocin analogue given into the lateral ventricles reduced penile erection induced by VGF(588-617), but not when injected into the paraventricular nucleus.

    In plain wordsIn male rats, a vasotocin-type compound in the brain ventricles reduced erections caused by a VGF peptide, but not when given into the paraventricular nucleus.

    Summary
    d(CH2)5Tyr(Me)-Orn8-vasotocin (1 microg) effectively reduced VGF(588-617)-induced penile erection when given into the lateral ventricles but not when injected into the paraventricular nucleus.

    Summary · context
    The effect of five peptides derived from the C-terminal portion of rat pro-VGF (VGF(577-617), VGF(588-617), VGF(599-617), VGF(556-576) and VGF(588-597)) on penile erection was studied after injection into the hypothalamic paraventricular nucleus of male rats.

  2. 02AnimalNot a test of Oxytocin aloneAnimal study (in vivo)Mechanism

    In the rat paraventricular nucleus, immunostained pro-VGF terminals impinged on parvocellular oxytocinergic neurons.

    In plain wordsIn rats, nerve endings containing a VGF peptide were found touching oxytocin-producing neurons in a brain area linked to erection.
