Summary

During the past year, data have been published on the offspring sex ratios of people diagnosed with toxoplasmosis, hepatitis B, and pre- and post-menopausal breast cancer. It is shown here how these offspring sex ratios constitute further support for the hypothesis that mammalian (including human) parental hormone concentrations around the time of conception partially control the sexes of the resulting infants. If this interpretation were correct, then hormonal treatments might be considered for some or all of these conditions. It is intended that anyone who has read the present note and my two previous papers (James, 1996, 2004) should be aware of all the data relating to the hypothesis.
