We have found in ultrasonic measurements, that the birth weight from newborn males and females is equal, if the biparietal diameter of the fetuses had been the same. Opposite we found by measuring the equal thoracic transversal diameter, that the birthweight of the males was about 200 bis 300 g higher than that of the females.
我们通过超声测量发现,如果胎儿的双顶径相同,新生男婴和女婴的出生体重相等。相反,在测量相同的胸廓横径时,我们发现男婴的出生体重比女婴高约200至300克。
