Sexual differentiation in humans is the process of development of sex differences in humans. It is defined as the development of phenotypic structures consequent to the action of hormones produced following gonadal determination. The development of sexual differences begins with the XY sex-determination system that is present in humans, and complex mechanisms are responsible for the development of the phenotypic differences between male and female humans from an undifferentiated zygote. At an early stage in embryonic development, both sexes possess equivalent internal structures.

Fetal Development Month by Month

The organs and structures of the female reproductive system give women the ability to produce a baby. They do this by producing eggs to be fertilised by sperm from a man. They also provide a place for the baby fetus to grow and develop. Other structures such as the breasts give the mother the ability to feed and nourish a baby after birth. The organs of the female reproductive system are found both inside and outside of the female body.
