• Background Ureaplasma species are common pathogens of the urogenital tract and can cause a range of diseases. Unfortunately, there is still a scarcity of large-scale and cross-sectional studies on the prevalence of Ureaplasma species in China to clarify their epidemic patterns. Methods This study retrospectively analyzed the data of 18667 patients who visited Peking Union Medical College Hospital for showing various symptoms of (suspected) Ureaplasma species infection during the period 2013–2022. The overall prevalence of Ureaplasma species was calculated, and subgroup analyses were conducted in view of gender, age, specimen types, and diagnosis in every year within the period studied. Furthermore, previous literature that reported on the prevalence of Ureaplasma species in various regions of China was searched and summarized. Results The overall positive rate of Ureaplasma species in this study reached 42.1% (7861/18667). Specifically, the prevalence of Ureaplasma species was significantly higher in female patients, while the highest detection rate was found in the 21–50 age group. From 2013 to 2022, there were no significant differences in positive rates of Ureaplasma species among years. However, the detection rate of Ureaplasma species was decreased in COVID-19 period (2020–2022) compared to pre-COVID-19 period (2017–2019). In view of the distribution of patients, outpatients predominated, but the detection rate was lower than inpatients. Urine was the most common specimen type, while cervical swabs had the highest detection rate of Ureaplasma species. When grouped by diagnosis, the highest positive rate of Ureaplasma species was seen in patients with adverse pregnancy outcomes and the lowest rate in patients with prostate disease. The previous literature, although heterogeneous, collectively suggested a high prevalence of Ureaplasma species in China. Conclusions Our study has shown that Ureaplasma species have reached a significant prevalence in China and demands adequate attention.
