Uterus Masculinus. a part of the urogenital system in the males of certain vertebrates, for example, elasmobranchs and mammals.In a number of animals, including primates, rodents, and lagomorphs, the uterus masculinus becomes the prostatic utricle, which fills the prostate gland with secretions during sexual activity.

Understanding Uterus-Masculinus in Mammals
The uterus-masculinus is a structure found in certain mammals, particularly in some male species, and it is derived from the Müllerian duct. Here’s a detailed explanation:
Development of Reproductive Structures
- During embryonic development, both males and females initially have the same set of reproductive structures.
- Two key ducts are involved:
- Müllerian Ducts: These are the precursors to female reproductive structures.
- Wolffian Ducts: These develop into male reproductive structures.
Role of Müllerian Duct
- In typical male mammals, the presence of testosterone leads to the regression of Müllerian ducts, which usually develop into the female reproductive system.
- However, in some species, remnants of the Müllerian duct can persist and develop into the uterus-masculinus.
- The uterus-masculinus serves various functions depending on the species, including potential roles in reproductive processes or as a vestigial structure.
Conclusion
- The correct answer to the question regarding the derivation of the uterus-masculinus in mammals is indeed C) Müllerian duct.
- Understanding this derivation helps clarify the complexity of sexual differentiation and the evolutionary adaptations in mammalian reproductive anatomy.
This highlights the importance of the Müllerian duct in the context of both male and female reproductive system development.
