Background: Several genital pathogens affect fertility. The study estimated the seroprevalence of Treponema pallidum, Ureaplasma urealyticum, and Mycoplasma hominis and identify specific factors associated with exposure to at least one of these pathogens in patients seeking fertility treatment in the Emirate of Abu Dhabi, United Arab Emirates. Methods: A seroepidemiological survey was conducted in a major fertility clinic in the Emirate of Abu Dhabi. Serum samples were screened for eight immunoglobulins (IgG, IgM, and IgA) against T. pallidum, U. urealyticum, and M. hominis using enzyme-linked immunoassays. Factors associated with seropositivity to at least one of the pathogens were investigated. Results: The study surveyed 308 patients seeking fertility treatment (mean age: 36.1 ± 6.8 years). Most patients were female (88.0%), 24.9% had at least one chronic comorbidity, 19.3% had a previous genital infection, and 68.1% had been diagnosed with infertility for ≥ 6 months. Ig seroprevalence of T. pallidum (IgG: 3.0%, IgM: 3.2%), U. urealyticum (IgG: 2.6%, IgM: 2.0%), and M. hominis (IgG: 33.9%) was 6.4%, 4.6%, and 49.0%, respectively. Nearly one quarter (23.0%) and one decile (9.2%) of the patients exhibited evidence of ongoing infection (IgM seropositivity) or recent infection (IgA seropositivity) with M. hominis, respectively. Overall, 53.0% of the patients were seropositive for at least one of the screened immunoglobulins. Patients with an education level of secondary schooling or below (66.2%) or those who were unemployed (61.1%) had a higher seroprevalence of IgG antibodies compared with patients with college or higher-level education (48.4%) or those who were employed (48.1%) (p |
