When the pregnancy reaches 23 weeks, the woman is in the sixth month of gestation. At this time, the baby is about 27-29 cm long if the legs are taken into account or 20-21 cm if measured from the skull to the buttocks. In addition, its weight is around 450-500 grams. Therefore, the size of the baby at 23 weeks is often compared to that of an ear of corn.
