What does Biparietal diameter mean?
BPD (biparietal diameter), the diameter of your baby’s head. HC (head circumference), the length going around your baby’s head.
What is normal BPD at birth?
The mean BPD at birth was 9.0 cm. The average body weight was 2642 g. Fetal maturity was determined by Petrussa score, serving as an estimate for gestational age. The mean gestational age of the 202 newborns was 39 weeks.

What is the Biparietal diameter used for?
Biparietal diameter (BPD) is one of the basic biometric parameters used to assess fetal size. BPD together with head circumference (HC), abdominal circumference (AC), and femur length (FL) are computed to produce an estimate of fetal weight.
What is normal BPD in pregnancy for boy?
At 24 weeks, the 50th percentile BPD for boys (60.4 mm) is significantly higher as compared to girls (58.9 mm, p < 0.001; Additional file 5). This corresponds to a difference of three gestational days.
What is a normal BPD at 32 weeks?
Results: The mean biparietal diameter value was 29.4mm at 14 weeks, 49.4mm at 20 weeks, 78.4mm at 30 weeks, 91.5 at 37 weeks and 95.6mm at 40 weeks.
What is the BPD of baby girl?
At 24 weeks, the 50th percentile BPD for boys (60.4 mm) is significantly higher as compared to girls (58.9 mm, p < 0.001; Additional file 5).
What is maximum BPD for normal delivery?
Your doctor is looking for the BPD measurement, as well as the other measurements, to be within what is considered normal range. The biparietal diameter measurement increases from roughly 2.4 centimeters at 13 weeks to approximately 9.5 centimeters when a fetus is at term.
Can we know gender by BPD?
The accuracy of male prediction reached 100% at a BPD of 22 mm and that of the female at a BPD of 23 mm. The discrepancies between real and assigned sex ob- served demonstrated that female sex was documented in a male fetus (14 cases) more frequently than male sex was documented in a female fetus (six cases).
