High Prevalence of Chlamydia Trachomatis and Mycoplasma genitalium among Infertile Patients in Chongqing, China

Strategic Insights -

A new study published in BMC Infectious Diseases has shed light on the prevalence of Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), and Neisseria gonorrhoeae (NG) among outpatients of reproductive medicine centers in Chongqing, China. The study, which retrospectively analyzed data from 111,222 patients attending the Center for Reproductive Medicine of Women and Children's Hospital of Chongqing Medical University between 2018 and 2022, found that CT and MG infections exceeded NG, with single infections predominating. This high prevalence necessitates integrated sexually transmitted infection screening in infertility care.

Key Takeaways:

  • The study included 111,222 patients, with a mean age of 33.28 ± 5.49 years, ranging from 19 to 76 years.
  • The prevalence of CT positivity was significantly lower in males than females (1.93% vs. 2.57%, p < 0.01).
  • MG infections were found to be more prevalent in females than males (2.45% vs. 1.85%, p < 0.01).
  • The prevalence of NG was significantly lower than CT and MG, with 0.85% positivity in males and 0.83% positivity in females.
  • The study found that CT and MG infections exceeded NG, with single infections predominating.
  • The research concluded that integrated sexually transmitted infection screening in infertility care is necessary due to the high prevalence of these infections.

Statistics:

  • 111,222 patients were included in the study.
  • The mean age of the patients was 33.28 ± 5.49 years.
  • The range of age was 19 to 76 years.
