Amniotic fluid concentrations of SP-A in women at term with and without labor stratified by gender of the fetus. There was no significant difference in the median amniotic fluid concentration of SP-A stratified by fetal gender in both the term in labor and term not in labor groups (term no labor SP-A female: median 5.7 μg/ml, range 2.2–15.2 μg/ml vs. male: median 5.3 μg/ml, range 2.6–11.7 μg/ml; p=0.8 and term in labor SP-A female: median 2.4 μg/ml, range 1.7–4.1 μg/ml vs. male: median 3.0 μg/ml, range 1.2–10.1 μg/ml; p=0.2).
