Men and women have the same number of ribs and there is no difference in gender. Both men and women have 12 ribs on the left and right side. In fact, the number of ribs is completely determined after birth and does not change afterwards. Although the rib cartilage in the front may ossify into bone at the end of growth and development, the number of ribs as a whole does not change and there is no difference in gender. Some patients have read in the Bible that God took out one of the man’s ribs and turned it into a female bone, so women have one less rib than men; this statement is just a mythological one and does not exist. In anatomy, it is clear to see that the number of ribs in men and women are exactly equal. In fact, the number of bones in all adults is essentially determined at 206. Although anatomical variation sometimes occurs, this variation does not differ by sex, which means that the number of bones in men and women is essentially equal.
