8 weeks, 1 day

From The Biology of Prenatal Development.Buy Now

Script: À ce point, les reins produisent de l'urine qui est libérée dans le liquide amniotique.

Chez les embryons masculins, les testicules en développement commencent à produire et à libérer de la testostérone.

Les os, articulations, muscles, nerfs, et vaisseaux sanguins des membres ressemblent de près à ceux de l'adulte.

All ages referenced to fertilization, not last menstrual period.
