This study explores the management and outcomes of planned, full-term pregnancies in patients with phenylketonuria (PKU). Method Married patients with PKU from 2012 to 2017 were enrolled to receive prenatal counseling and regular health assessments. Study-related assessments included the timing of Phe-restricted diets, maternal weight gain, gestational age, pregnancy complications, and blood Phe concentrations (both pre-conception and during pregnancy), obstetrical data, and offspring outcomes(e.g. anthropomorphic measurements and developmental quotients [DQs]). Results A total of six offspring were successfully delivered. The mean ± SD (range) age of the mother at delivery was 26.3 ± 4.7 (range: 21.1–32.5) years. The mean duration of Phe control before pregnancy was 5.5 ± 1.3(range: 3.1–6.5) months. During pregnancy, the proportion of blood Phe concentrations within the clinically-recommended target range (120–360 μmol/L) ranged from 63.2–83.5%. Low birth weight (
