Sex ratio in the progeny of mothers with toxemia of pregnancy.
Maternal-fetal incompatibility may be an essential component in the etiology of toxemia of pregnancy. A prior study found an abnormally high sex (male:female) ratio, suggestuve of Y-dependent histoincompatibility. We studied the records of 373 patients alleged to have some indication of toxemia among 3,246 births and applied standard criteria for classification. There were no significant differences for any group compared with the sexondary sex ratio expected of the population(94.6% Black).
