The Prevalence of Sexually Transmitted Infections among Male Patients at a Dermato-Venereology Outpatient Clinic in Gdańsk, Poland: Findings from a Single-Center Study.

Background: Sexually transmitted infections (STIs) are a significant public health concern worldwide, yet data on their prevalence and epidemiology, particularly in Central and Eastern Europe, remain scarce. This study aimed to assess the prevalence, anatomical localization, symptomatic/asymptomatic course, and co-infection patterns of STIs among men. Methods: This retrospective study analyzed data collected between May 2021 and July 2023, including sociodemographic, sexual behavior, and clinical data from 139 male participants. Molecular polymerase chain reaction (PCR) tests were conducted for Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Mycoplasma genitalium, and Trichomonas vaginalis. Results: Of the participants, 36% tested positive for at least one STI, with the urethra being the most common site of infection. NG and CT were the most prevalent infections. The majority of infections were asymptomatic, highlighting the importance of comprehensive screening, especially in high-risk populations like men who have sex with men (MSM). Conclusions: This study emphasizes the need for targeted screening strategies, particularly for extragenital STIs, and underscores the role of MSM in STI epidemiology. The findings highlight the importance of routine screening, even for asymptomatic individuals, to effectively control STI spread. Future research should validate and expand upon these findings to enhance STI prevention and management efforts.
