Correct Answer: no physical symptoms or findings
trichomoniasis is a sexually transmitted infection caused by the protozoan parasite trichomonas vaginalis. while this infection is well-known for its symptoms in females, such as itching, discomfort, and abnormal discharge, the presentation in males can often be quite different, leading to potential underdiagnosis in this population.
in males, trichomoniasis may frequently present without any symptoms or physical findings at all. this asymptomatic nature can contribute to the continued spread of the infection, as individuals may not be aware that they are infected and thus do not seek treatment. when symptoms do occur in males, they are typically less severe than in females. the most common manifestation in symptomatic males is urethritis, an inflammation of the urethra, which can cause symptoms such as a burning sensation during urination or a mild discharge.
other potential but less common symptoms in males include itching or irritation inside the penis, discomfort during urination, or slight redness or swelling at the urinary opening. it is important to note that these symptoms can be mistaken for other conditions such as urinary tract infections or other sexually transmitted infections.
the options provided in the question—prostadynia (or prostatitis), pyuria, and gray-green urethral discharge—are less typical of trichomoniasis in males. prostadynia, which refers to pain in the prostate gland without significant inflammation, and prostatitis, which is the actual inflammation of the prostate, are generally not associated with trichomoniasis. pyuria, the presence of pus in the urine indicating an infection, could theoretically occur but is not a specific indicator of trichomoniasis. likewise, while urethral discharge in males can occur, it is not typically gray-green but rather clear or white if present.
therefore, the correct answer to the question is "no physical symptoms or findings," which reflects the often asymptomatic nature of trichomoniasis in males. understanding this aspect of the disease is crucial for healthcare providers to consider screening for trichomoniasis in sexually active males, particularly those with known exposure or whose partners are symptomatic, to prevent ongoing transmission and complications associated with untreated infections.
