Large amounts of leukocytes in the seminal fluid suggest a clinical finding of
Correct Answer: C
Rationale: Large amounts of leukocytes in seminal fluid indicate an infection of the genital tract. Leukocytes are white blood cells that are typically present in response to an infection. In this context, their presence suggests an ongoing inflammatory response to combat the infection. This finding is consistent with an infection in the genital tract, which could be caused by various pathogens. Therefore, choice C is the correct answer.
Choice A (inadequate fructose) is incorrect because leukocytes are not directly related to fructose levels in the seminal fluid. Choice B (inflammation of the testes) is incorrect as the presence of leukocytes in seminal fluid does not necessarily indicate testicular inflammation. Choice D (obstruction in the vas deferens) is also incorrect as leukocytes are not typically associated with vas deferens obstruction.
