  • We found that after oxytocin administration, fathers' salivary oxytocin rose dramatically, more than 10 fold, but moreover, similar increases were found in the infants' oxytocin. (redorbit.com)
  • Increases in oxytocin following high contact interactions have been shown in correlational studies. (wikipedia.org)
  • vesicles
