Causes of short femur length in fetus

The fetus's femur is relatively short. As a mother, first of all, don't worry too much. This is just a measurement value. There may be certain differences when measuring due to different positions. It may also be related to genetics or fetal malnutrition. As a mother, you should pay attention to your daily life, have a good diet, get enough rest, and do corresponding examinations in time.

What to do if the fetus's femur is too short

1. Measurement errors: When measuring the femur length after 30 weeks of pregnancy, an error of up or down two weeks is allowed. As long as it is within this range, pregnant mothers do not need to worry too much. 2. Fetal maldevelopment: If the femur length measurement is very different from the standard value, it is very likely that the fetus is maldeveloped. Pregnant women should monitor the health of their babies and themselves. If they have irregular abdominal pain, spotting, etc., they should go to the hospital for examination in time.

Biparietal diameter femur length male and female

It is said that if the value of the fetus's biparietal diameter minus the femur length is greater than 2, there is a greater possibility of giving birth to a boy in the future. Experts say there is no scientific basis for judging whether a baby is a boy or a girl based on the difference in biparietal diameter and femur length. Femur length is an indicator for doctors to observe fetal development and predict the baby's weight. In addition, the measured biparietal diameter and femur length data will vary depending on the fetal position. Therefore, it is inaccurate to determine the gender of the baby based on the biparietal diameter and femur length. If you want to determine the sex of the fetus, you can choose to have an ultrasound examination.
