This prospective multicenter study aims to determine the point prevalence, incidence, and recurrence of sexually transmitted infections (STIs) in men who have sex with men (MSM) in Germany. The study also evaluates the relationship between STI rates and PrEP use. Preliminary findings reveal a high prevalence of STIs, including gonorrhea, chlamydia, and mycoplasma genitalium, among MSM at risk for HIV infection. The study will help assess the impact of PrEP on STI rates and guide targeted interventions to reduce STI transmission in this population.
