Fifteen week old foetus. Computer graphic of a human foetus in side view, 15 weeks ( months) old. At this age the foetus appears completely human with lips, eyelids and external ears. Fingers and toes are formed, and the arms, legs and face appear thin due to a lack of subcutaneous fat. At this time the foetus is covered in fine hair and eyebrows and head hair are forming. The crown-rump length (sitting height) of the foetus is about 13-14cm and its weight 180-200g. The head is proportionately large, although the body is elongating at this stage. The sex of the foetus is well established, although not seen here.
