Description
Eric Ofori is lead author of a 2026 prospective study of fetal blood flow patterns by sex in a Ghanaian pregnancy cohort. Ultrasound Doppler measures track blood flow in the cord, the fetal brain artery, and the fetal aorta. They may differ between male and female fetuses. But African data on this question are limited.
Among 239 low-risk singleton pregnancies, 53.6 percent of fetuses were male. Pooling all pregnancy stages, no Doppler index differed clearly by sex. Before 25 weeks, though, female fetuses showed higher cord artery resistance measures, suggesting tighter flow through the placenta, while males showed higher aorta resistance measures. The authors present these early patterns as sex-specific physiology worth tracking.
