Begin by observing the internal structure of the embryo at the end of week 4 and the beginning of week 5.
Colour code:

Mesonephros and Mesonephric Duct
D7-G4: Section passes dorsally to the mesonephros. Return to G4 and then follow the caudal route of the mesonephric duct into the sacral region.

Now go back and observe the development of the intermediate mesoderm.

Primitive Urogenital Sinus
Gonad Development
Male Testis
Female Ovary
Gonadal Development Comparison
Now directly compare the development of the male and female gonad (click image to start, these may not be synchronised).
