  1. 01HumanNon-randomized trialEfficacy outcome

    In obese men with impaired insulin sensitivity, a single intranasal oxytocin dose did not blunt postprandial glucose excursions during an oral glucose tolerance test.

    In plain wordsIn obese men, one oxytocin spray dose did not lower the rise in blood sugar after a sugar drink.

    Summary
    In contrast to the results in normal-weight subjects, oxytocin did not blunt postprandial glucose and insulin excursions in obese men, and moreover failed to enhance beta-cell responsivity and glucose tolerance.

    Summary · context
    In the present experiment, we investigated the acute glucoregulatory impact of oxytocin in obese men with impaired insulin sensitivity.
    Summary · context
    Fifteen obese healthy men with an average body mass index of 35 kg/m2 and an average body fat content of 33% received a single intranasal dose (24 IU) of oxytocin before undergoing an oral glucose tolerance test.
