Introduction
In general, a fetal femur length of 63 mm at 37 weeks of pregnancy is not likely to indicate an abnormality. The normal range for fetal femur length at 37 weeks is between 56 and 72 mm, and 63 mm falls within this normal range. Pregnant women are advised to consider other ultrasound findings as well, and comprehensively evaluate indicators such as head circumference, abdominal circumference, and biparietal diameter under the guidance of a physician to assess the fetus's health status.
Under normal circumstances, a femur length of 63 mm at 37 weeks of pregnancy is likely not indicative of a fetal abnormality. However, if any discomfort or unusual symptoms occur, it is recommended to seek medical attention promptly. The detailed explanation is as follows:
Fetal growth and development are influenced by various factors, including genetics, maternal nutritional status, and overall maternal health. Femur length is one of the indicators used to assess fetal growth, and its normal range increases with gestational age. At 37 weeks of pregnancy, the normal range for fetal femur length is between 56–72 mm. A measurement of 63 mm falls within this normal range and typically does not indicate a malformation. Pregnant women should consider other ultrasound findings as well, such as head circumference, abdominal circumference, and biparietal diameter, and comprehensively evaluate fetal health under the guidance of a healthcare provider.
Pregnant women should maintain a balanced diet, consuming foods rich in vitamins, proteins, and minerals to meet the nutritional demands of fetal growth and development.
