The impact of fetal gender on first trimester nuchal translucency and maternal serum free β‐hCG and PAPP‐A MoM in normal and trisomy 21 pregnancies

13 Mar 2009

Abstract excerpt

OBJECTIVE: To investigate if fetal sex has an impact on 1st trimester combined screening for aenuploidy. METHODS: We studied the first trimester PAPP-A, free beta-human chorionic gonadatropin (beta-hCG) and nuchal translucency levels in 56,024 normal, singleton pregnancies with known fetal sex at birth. We also examined the distributions in 722 pregnancies with trisomy 21 of known fetal sex. RESULTS: We have...
