The first sex organs, which are the gonads (ovaries in females and testes in males), are identical in male and female fetuses for the first month of pregnancy. It is not true that the first sex organs appear earlier in girls than in boys (or vice versa) or that the first sex organs appear only after the first 12 weeks of pregnancy. The development of male external genitalia occurs around week 9-10 of gestation, but this is not the first appearance of sex organs.
