Molecular prevalence of Chlamydia trachomatis infection among women attending gynaecological clinic for infertility evaluation
Abstract Background Chlamydia trachomatis is one of the most prevalent sexually transmitted bacterial infections and a significant cause of infertility in women. Despite its asymptomatic nature, the bacterium can ascend the reproductive tract, leading to pelvic inflammatory disease and tubal factor...

| description | Abstract Background Chlamydia trachomatis is one of the most prevalent sexually transmitted bacterial infections and a significant cause of infertility in women. Despite its asymptomatic nature, the bacterium can ascend the reproductive tract, leading to pelvic inflammatory disease and tubal factor infertility. Objective This study investigated the molecular prevalence of Chlamydia trachomatis infection (CTI) among women attending a gynaecological clinic for infertility evaluation. Methods This cross-sectional study involving 135 women was conducted at Edo University Teaching Hospital, Auchi, Nigeria. Endocervical swabs were collected during speculum examination and stored in DNA stabilization buffer at − 20 °C. Genomic DNA was extracted using the Qiagen DNA extraction kit, followed by PCR amplification targeting the ompA gene of C. trachomatis. Socio-demographic and clinical data were collected via structured questionnaires. Statistical significance was assessed using IBM SPSS Statistics version 25 (IBM Corp.) and the Chi-square test, with significance defined as p < 0.05. Results Out of 135 women screened, the molecular prevalence of CTI was 27.4%. The highest rate occurred among women of 18–26 years of age (31.6%), although age differences were not statistically significant (p = 0.38). Chlamydia trachomatis infection was significantly associated with a history of STIs (40.0% vs. 20.0%, p = 0.02) and PID (45.0% vs. 20.0%, p = 0.01). Women with secondary education had a higher prevalence (36.7%) than those with tertiary education (20.0%) (p = 0.05). No significant association was observed between vaginal symptoms and infection status, with malodorous discharge also failing to demonstrate statistical significance (p = 0.08). Logistic regression identified younger age (18–26 age group) (OR = 0.46, p = 0.007), STI history (OR = 0.24, p < 0.001), and PID (OR = 2.67, p = 0.005) as significant predictors of CTI. Tertiary education was protective (OR = 0.42, p = 0.028). Conclusion Chlamydia trachomatis infection was prevalent among women attending a gynaecological clinic for infertility. Younger age, a history of STIs, and PID were significant predictors of infection, while tertiary education appeared protective. Targeted screening and educational interventions are essential to mitigate infection-related infertility. |
