In a study of the haemoglobin concentrations of 408 male and 789 female blood donors aged 18–65, it was found that in both sexes the haemoglobin level, except for a peak in the middle of the third decade, remained constant until the fifth decade. From this period to the age of 65, there was a progressive and significant decrease of haemoglobin concentration in men and a progressive and significant increase of haemoglobin concentration in women. An initial difference in haemoglobin level, between men and women, of almost 2 g/100 ml in the early twenties was reduced to just over 1 g/100 ml in the middle sixties. Possible reasons for the above differences were discussed with emphasis on the effects of hormonal environment and iron deficiency.
