Women who have been diagnosed with cardiovascular disease are more likely to have baby girls than baby boys, a study presented at the World Congress of Cardiology shows. "We believe that this is the first study looking at the relationship between gender and the mother's cardiac disease," says Dr. A. Alizadehasl of Tabriz University in Iran.
The findings resulted from a study of 216 children whose mothers had been diagnosed with cardiovascular disease. Of these 200 mothers, 64 percent had valvular disease, 19 percent had dilated cardiomyopathy, and 14 percent had uncorrected or significant residual congenital heart disease. Of the 216 children, 75 percent were girls.
Considering that the chromosomes in men’s sperm usually determine the sex of the baby, this discovery implies that other factors may also affect whether an infant is a girl or a boy. Still, nothing is completely definitive. Expectant mothers who have been diagnosed with cardiovascular disease shouldn’t buy pink pillows just yet. Until the ultrasound results come out, it’s best to keep your options open.
