The bleeding time by a modified Ivy technique was estimated on 128 normal volunteers,
59 men and 69 women. The bleeding time was found to be significantly longer in women
than men (p<.001). This was not attributable to a difference in platelet count nor
to any detectable difference in platelet aggregability. It is likely that a difference
in blood vessels or supporting tissues is responsible for the observed difference.
