Why do men and women differ from each other in body structure?

A man and a woman are two different sexes of a person. The sex of a person is determined at the stage of intrauterine development. We are all asexual at first. At 6 weeks of development in the womb, sexual definitions begin and all people develop as girls first. A child can become a boy at 10-11 weeks under the influence of hormones. From this point on, we begin to develop in different ways. This is due to the action of sex hormones. All the differences between men and women are due to hormones. When a hormonal disruption occurs, then a person receives signs of the opposite sex, but not always these signs are anatomical.
