- Sexual differentiation begins close to 4 weeks after fertilization, but cannot be seen visually until about 6 weeks post fertilization. All fetuses begin with a ______________________ gonad that is able to become either ovaries or testes, depending on the presence or absence of the Y chromosome. If the Y chromosome is present, a region of the Y chromosome will begin expressing genes that start the process of masculinization of internal structures. This region is known as the ______________________________ region or ___________ for short. The expression of these genes causes the bipotential gonad to develop into the testes. Once the testes have started developing, two hormones, testosterone and Anti-MüllerianHormone are produced. Testosterone causes the _____________________ ducts to develop into the _____________________. Testosterone also causes the internal development of the __________________ and __________________.
