title: Effect of fetal sex and race on amniotic fluid lecithin concentration.
abstract: Amniotic fluid lecithin phosphorus concentration (AF-Lec) was measured in 209 healthy women at 31.7-42.7 weeks gestation. The patients were divided into four groups according to race and fetal sex. No differences in AF-Lec between black and white nor between male and female fetuses were found. The relationship of AF-Lec to gestational age and the incidence of "mature" AF-Lec was not different among the four groups. We conclude that there is no effect of fetal sex, race, or the interaction between them on fetal lung development as measured by AF-Lec.
