Abstract
Summary It is argued that the author's hypothesis relating timing of insemination (and hence coital rate) to the sex ratio of the resulting children is supported by the available data on the variation of sex ratio with (1) sibship size, (2) the presence of twin sibs, and (3) parental adherence to the Jewish faith.Keywords
