Have Ureaplasma urealyticum and Mycoplasma hominis infections any significant effect on women fertility?

Abstract

Ureaplasma urealyticum and Mycoplasma hominis are known as sexually transmitted agents. U. urealyticum and M. hominis jeopardize male fertility. However, it is unclear whether these infections significantly contribute to female infertility. In this controlled-study we aimed to establish whether M. hominis and U. urealyticum are risk factors for female fertility and prevalence of infection from these agents in patients attending our infertility clinic. Total 96 married women enrolled in this prospective study; the infertile (study) group consisted of 50 women and fertile (control) group comprised 46 women. The patients were searched about the presence of U. urealyticum and M. hominis by a micro-liquid culture method. The samples were collected from endocervical area with a dacron swab. 28 of 50 (56%) and 18 of 46 (39%) women were evaluated as positive for U. urealyticum culture in the study and control groups respectively. M. hominis was cultured from 4 of 50 (8%) women in the study group as no positive result in controls. There were no statistically significant differences between the groups for both agents (p>0.05), but the higher prevalence of U. urealyticum in infertile women gives emphasis to evaluate these agents in patients that have no any other etiological factor for infertility.
