Question
Hi Doctor,
I am 36 weeks pregnant with my first child. I went for a check-up and the results showed that my biparietal diameter was 89mm, my weight was 2.7kg, and my femur length was 62mm. Before that, I went for a check-up at 34 weeks and my weight was 2.4kg and my femur length was also 62mm. The doctor said that my femur length was short compared to my gestational age. Today, at 36 weeks, it is still only 62mm, which makes me very worried. No one in my family is dwarf, I am 1m67, and my baby's father is 1m78. So, doctor, can you tell me if a 36-week pregnancy with a femur length of 62mm has any effect?

Hello,
With the question "Is the 36-week-old fetus's femur length of 62mm a problem?", the doctor would like to answer as follows:
Firstly, the femur length of 62mm at week 36 is not short, it is not a sign of disease. The femur measurement at weeks 34 and 36 does not change, it may just be a measurement error, so you do not need to worry in this case. Second, if the femur is really short, there is currently no way to fix it in the fetus. Third, you should not predict the child's future height development based solely on the short femur length in the fetus because the child's bone development depends on many external factors such as living environment, nutrition, education, activities... genes are only a small factor. Therefore, you should rest assured about this information.
If you still have questions about the 36-week fetus with a 62mm femur length, you can go to a hospital in the Vinmec Health System for further examination and consultation. Thank you for your trust and sending questions to Vinmec. Wish you good health.
Sincerely!
