At around 22-26 weeks, the fetus reaches the stage of viability, where it has a chance of survival outside the womb with intensive medical assistance. Vernix and lanugo begin to cover the skin much earlier, around 14-16 weeks. Synchrony between the fetal heart rate and motor activity peaks around 32-36 weeks. The external genitals begin to form around 9 weeks.
