指比率是指胎儿期或出生后手指长度的比率(如第2比第4指或第2比第3指等),通常男性的均值低于女性。据相关研究表明,其值与围产期母体内的雄激素水平相关。现对指比率和围产期雄激素相关性的最新研究进展做一综述。有学者通过建立动物模型、测量围产期羊水中睾酮水平以及利用先天性肾上腺增生症患者作为模型,研究围产期母体内雄激素水平不同的情况下胎儿或其出生后指比率的变化,并将指比率与其他研究围产期母体内雄激素对胎儿作用的方法进行了比较。
Refers to the ratio refers to the rate of fetal or postnatal finger length (such as the second than the fourth or second than the third finger, etc.), the average male than the average. According to relevant research shows that its value and the perinatal maternal androgen levels. This review summarizes recent advances in the ratio and perinatal androgen related research. Some scholars through the establishment of animal models to measure perinatal amniotic fluid amniotic fluid levels and the use of congenital adrenal hyperplasia patients as a model to study perinatal maternal different androgen levels in fetal or postnatal ratio changes and The rates were compared with those of other studies examining the effect of androgens on the fetus in perinatal maternal age.
