There is no proven explanation for these age-related changes, although it may be that the sharp decrease in platelet count during infancy reflects the decline of thrombopoietin levels occurring from birth to adulthood.13 Concerning the mechanism of platelet reduction in old age, it has been suggested that it derives from a survival advantage of subjects with lower platelet counts or a reduction in hematopoietic stem cell reserve during aging.12 However, both these explanations are purely hypothetical, and further investigation is required to clarify this matter.
