Which gland in male rodents produces a mucous plug that remains in the female's vagina?

Prostate gland
Coagulating gland
Seminal vesicle
Bulbourethral gland

The correct answer is: Coagulating gland

The coagulating gland in male rodents specifically secretes a mucous plug that is critical for reproduction. This mucous plug serves to block the female's vagina after mating, thereby helping to ensure that the sperm have a higher chance of fertilizing the eggs. The presence of this plug increases the likelihood that the sperm will remain in the female reproductive tract, which is essential for successful reproduction in rodent species. The role of the coagulating gland is particularly significant given that it aids in maintaining sperm viability and protecting the sperm from being displaced following mating. This process is a well-documented reproductive strategy in many rodent species and highlights the unique adaptations that have evolved in these animals to enhance reproductive success.
