Describe the role of the Müllerian ducts and the Wolffian ducts in the female and the male, respectively.

The Müllerian ducts and the Wolffian ducts are both related to the process of prenatal sexual differentiation. Once the gonads have differentiated into testes and ovaries in the male and female respectively, these organs begin to produce different sex hormones which direct the differentiation of the rest of the internal and external genital system. The Müllerian ducts and the Wolffian ducts are found in both males and females, however, in females, the Wolffian ducts degenerate, and the Müllerian ducts turn into the fallopian tubes, the uterus, and the upper part of the vagina. In the case of males, the opposite occurs. The testes secrete the Müllerian inhibiting substance (MIS), which causes the Müllerian ducts to degenerate, while the Wolffian ducts turn into the epididymis, the vas deferens, and the ejaculatory duct.
