Summary A fertility survey, carried out on several thousand East Anglian blood donors, gives no indication of real differences in human fertility associated with differences in the ABO blood‐group constitution. However, the reproductive differences between individuals are much greater than those which can be attributed to chance and the data lend no support to the view, recently propounded, that the lowering of childhood mortality in modern times has resulted in a uniform fertility and the elimination of a selective differential in reproduction. The data indicate (i) that childlessness is more frequent, though not quite significantly so, amongst married women of groups A and B than amongst those of groups O and AB , and (ii) that children of group O Rh ‐positive fathers are significantly more likely to die under ten years of age than other children. Our thanks are due to the East Anglian Regional Hospital Board for tabulating and sorting the data on Hollerith machines.
