Background and objectives: Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) are two commensal microorganisms that form the urogenital microbiota. Under a state of dysbiosis, both bacteria cause intrauterine infection. Material and methods: Therefore, the purpose of the present study was to analyze the prevalence of UU and MH among four hundred and eleven infertile women. Results: Women between thirty and thirty-five years old were the most affected group, followed by those that were 25 and 30 years old, respectively. Cumulatively, the prevalence of single UU and MH, and coinfection, was 28.46% (n = 117), (n = 2) 0.48%, and 2.91% (n = 12), respectively, with an overall detection rate of 31.87% (n = 131). To assess the associated drug susceptibility, endocervical samples were unequally sent to Regina Maria (n = 281) and Synevo (n = 130) laboratories for further analyses. Pristinamycin (100% vs. 100%) and Josamycin (100% vs. 98.00%) were the most efficient antibiotics in eradicating UU and MH, several others also displaying a high efficiency, among which can be mentioned Doxycycline (98.23%), Minocycline (96.00%), Tetracycline (96.48% vs. 68.00%), and Erythromycin (70.17% vs. 92.00%). Based on antibiograms, Clarithromycin (88.00%), Roxithromycin (88.00%), Levofloxacin (82.00%), and Azithromycin (78.94%) can be further used in treating such infections. On the other hand, Clindamycin (4.00%) and Ciprofloxacin (12.27% vs. 2.00%) are no longer viable because both UU and MH display an intermediate response towards gained resistance. Interestingly, the efficiency of Ofloxacin (22.79% vs. 60.00%) was conflicting, this possibly suggesting a transient stage to a gradual adaptability of these microorganisms to Ofloxacin. Conclusions: The most susceptible age groups in each case were women that were between twenty and forty years old. It can be concluded that four antibiotics can be safely used for treating UU, MH, or dual infections whose efficiency was over 95%.
