Infecção por Chlamydia trachomatis e Neisseria gonorrhoeae: Fatores associados à infertilidade em mulheres atendidas em um serviço público de reprodução humana

Abstract

Purpose: To evaluate the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in women undergoing assisted reproduction in a public reference service in the midwestern region of Brazil. Methods: A cross-sectional study was conducted on 340 women aged from 20 to 47 years with a history of infertility, undergoing assisted reproduction techniques. Infections with Chlamydia trachomatis and Neisseria gonorrhoeae identified in urine specimens by PCR, and the profile of infertility were analyzed. We used the χ2 test or Fisher's exact test to evaluate the association between infection and variables. Results: The prevalence of Chlamydia trachomatis infection was 10.9%, and Neisseria gonorrhoeae co-infection was observed in 2 cases. Women infected with Chlamydia trachomatis had more than 10 years of infertility (54.1%; p<0.0001). The tubal factor was the main cause in infected cases (56.8%; p=0.047). Tubal occlusion was found in 67.6% of cases with positive infection (p=0.004). Conclusion: There was an association of tubal obstruction with infection by Chlamydia trachomatis and Neisseria gonorrhoeae, reinforcing the need for effective strategies for an early detection of sexually transmitted diseases, especially in asymptomatic women of childbearing age.
