title: Disaturated phosphatidylcholine as a fetal lung maturity test: lack of interference by seminal ejaculate as a contaminant in vaginally pooled amniotic fluid samples.
abstract: Seminal ejaculates obtained from four men were added to amniotic fluid pools. Lecithin/sphingomyelin ratios in amniotic fluid were significantly lowered in the presence of small amounts of contaminating semen. In contrast, the determination of disaturated phosphatidylcholine was not affected by the presence of this contaminant.
