What should AFI be at 28 weeks?
This study and some of the previous studies (6–12,17,18,) showed that AFI decreases gradually as the gestational age advances in the third trimester to 42 weeks and that the range of the AFI in the third trimester (28–42 weeks) are within 8–25 cm. According to Shripad et al.
What is the femur length of baby Boy?
Femur length (FL) Measures the longest bone in the body and reflects the longitudinal growth of the fetus. Its usefulness is similar to the BPD. It increases from about 1.5 cm at 14 weeks to about 7.8 cm at term.
Can you tell gender by femur?
The average diameter of the head of the femur is therefore different in different races. Purkait (11) showed that if the vertical diameter of the head of the femur was greater than 48.00mm, the bone belongs to a male bone and when below 44.00mm, it belongs to a female bone.

What is normal AFI at 30weeks?
From a median of 10.3 cm (range, 8.7-13.7, 5th-95th percentile) at 15 weeks’ gestation, the amniotic fluid index rose progressively to a maximum median of 14.0 cm (range, 4.0-18.6) at 30 weeks. The index then gradually declined to a median of 9.1 cm (range, 4.8-14.2) by 40 weeks’ gestation.
