Video - Development of the reproductive system

The early stage of both male and female reproductive system development are indifferent because it's impossible to distinguish between the male and female gonads at that time. It is until week seven that the primitive structures start to differentiate into female or male sex organs based on the present sex chromosomes. After the ovaries or testicles develop, further differentiation of the reproductive tract occurs, giving rise to corresponding male or female sex organs. Ovaries and the testis are initially developed in the abdomen and descend later during pregnancy to reach their final location in the pelvic cavity and the scrotum.
