What week does the gender form?

Boys' and girls' genitals develop along the same path with no outward sign of gender until about nine weeks. It's at that point that the genital tubercle begins to develop into a penis or clitoris. However, it's not until 14 or 15 weeks that you can clearly begin to see the differentiated genitalia.

At what week do you become male or female?

During early development the gonads of the fetus remain undifferentiated; that is, all fetal genitalia are the same and are phenotypically female. After approximately 6 to 7 weeks of gestation, however, the expression of a gene on the Y chromosome induces changes that result in the development of the testes.

Can you tell gender at 12 weeks?

The earliest time we can assess the baby's sex is at 12 weeks gestation/pregnancy: We can tell the sex of the baby at the 12 week scan by assessing the direction of the nub. This is something that can be identified on babies at this stage and if it points vertically then it is likely to be a boy.
