Embryonic Sex Differentiation and Reproductive Ducts

Embryonic sex differentiation begins with a bipotential stage. At this point, the early embryo can form either male or female reproductive organs. During the fifth week of development, gonadal ridges grow from the intermediate mesoderm. Nearby, two duct systems are present: the mesonephric ducts, also called Wolffian ducts, ...

The human embryo is bipotential, allowing the formation of either male or female reproductive organs.

During the fifth week of embryonic development, the gonads originate from gonadal ridges in the intermediate mesoderm.

Alongside these ridges, the mesonephric ducts, also known as Wolffian ducts, and the paramesonephric ducts, or M...
