title: Tactile stimulus and neurohormonal response: a pilot study.
abstract: The effects of tactile stimuli on plasma oxytocin and neuropeptide Y (NPY) were investigated in 21 volunteers exposed to massage. Blood samples for basal values were drawn immediately before and immediately after finishing the massage. A third sample was drawn after 60 min of restricted rest. On focusing on the difference between oxytocin concentrations before and immediately after massage, we found a sex difference. An opposite sex difference was found for NPY. The results imply that there might be sex-related difference in neurohormonal response to tactile stimuli such as in massage, and the results contradict those of previously reported animal experiments.
