Platelet adhesiveness was measured at intervals during the menstrual cycle in six normal females. Three normal males were studied during the .tame period of time to serve as controls. There was a significant difference of the variation of platelet adhesiveness between the two groups during the period of 30 days. Five out of six females showed much greater fluctuation than the males. No definite trend was observed in the platelet adhesiveness of females in relation to the menstrual cycle in this preliminary study. A larger number of samples from the population will be necessary to obtain a more accurate result.
