Fetal femoral length begins to be determined from the 14th week of pregnancy and is always maintained with subsequent visits. In addition to assessing fetal development, femur length is also significant in detecting Down syndrome of the fetus.
2. Standard femur length index of 37 weeks fetus
Week 37 is the week that is close to giving birth for pregnant women, so the index, especially the baby's femur length index, needs attention. Below is the standard femur length (FL) of a normally developing baby at 37 weeks plus 6 days:
FL week 37+0: 66-67mm, mean 70mm FL week 37+1 : 66-67mm, average 70mm FL week 37+2: 66-80mm, average 70mm FL week 37+3: 66-80mm, mean 71mm FL week 37+4: 66-80mm, mean 71mm FL week 37 +5: 67-80mm, average 71mm FL week 37+6: 67-81mm, average 71mm To have a healthy pregnancy, pregnant mothers need to build a reasonable diet, eat scientifically so that the mother does not gain too much or too little weight while the fetus still receives adequate nutrients.
