Human anencephalic infants have always been considered not to have circulating levels of oxytocin or vasopressin. However, this article shows that amniotic oxytocin levels in anencephalic infants without hydramnios fall within the control range. In addition, low levels of both oxytocin and vasopressin are present in the umbilical circulation. These peptides are probably derived from fetal sources other than the fetal brain, for example, the fetal adrenal cortex.
无脑儿一直被认为其循环系统中不存在催产素或加压素。然而，本文表明，无脑且无羊水过多的婴儿羊水中的催产素水平处于正常范围内。此外，脐循环中存在低水平的催产素和加压素。这些肽可能来源于胎儿大脑以外的其他胎儿组织，例如胎儿肾上腺皮质。
