The correct Answer is:
To determine which structure is not formed by the Wolffian duct, we can analyze the options provided: 1. **Understand the Wolffian Duct**: The Wolffian duct, also known as the mesonephric duct, is an embryonic structure that plays a crucial role in the development of the male reproductive system. It is influenced by testosterone during male sexual differentiation. 2. **Identify the Structures Formed by the Wolffian Duct**: - **Epididymis**: This is a structure where sperm mature and is indeed derived from the Wolffian duct. - **Vas deferens**: This duct transports sperm from the epididymis to the ejaculatory duct and is also formed from the Wolffian duct. - **Ejaculatory duct**: This duct is formed by the union of the vas deferens and the seminal vesicle duct, and it is derived from the Wolffian duct as well. 3. **Analyze the Fourth Option**: - **Oviduct (Fallopian Tube)**: The oviduct is part of the female reproductive system and is derived from the Müllerian duct (paramesonephric duct), not the Wolffian duct. 4. **Conclusion**: Since the oviduct is not formed by the Wolffian duct, the correct answer is option D. ### Final Answer: The structure that is not formed by the Wolffian duct is **option D: oviduct**.
