Mycoplasma hominis bacterial Role in infertile men with abnormal Semen

Background and Aim : Mycoplasma hominis is one of the most microorganism due to infertility. The aim is to test the prevalence of Mycoplasma hominis in infertile men. The patients that arrive to infertility clinics (Royan Institute in Tehran) with the semen culture analysis request are asked to fill in a questionnaire about infertility smear collection.Methods : In this case control study presence of M.hominis were analyzed in tested men. we have compared ۴۰ infertile males with unexplained infertility and ۴۰ Normal men with Female factor as a control case group. The samples were sent to microbiology laboratory. The information were analyzed with SPSS software by frequency, chi-square & T-test Method.Results : The average age in patients and control groups were ۳۱.۹۷۵.۵۴ and ۳۱.۹.۲۵.۹ the value of M.hominis in infertile cases were ۷(۱۷.۵%) and in Normal men were ۲(۵%). (X=۳.۱۳) and (P=۰.۰۷۷) then we have not found statistically significant differences in the M.hominis frequency of the patients. But we have found statistically significant relations between educational levels, the history of and infertility. Also we have not found statistically significant relations between history of libido, history of Impotency history of premature ejaculation, history of abdominal pain, history of testis pain history of smoking and infertility.Conclusion : We have shown a significantly M.hominis infections increase in the infertile men. The similarities between this study and the results obtained by others are limited and it may be due to different cultural and normal values in various societies. Though statistically non-significant due to limited number of subjects, however the difference observed in the prevalence infection between cases and controls indicates an association between Mycoplasma hominis infection and infertility. So, it is suggested to check up those patient with unexplained infertility, for genital micro-organisms infections, and if positive, to control the rate of infertility with a suitable and cost effective therapy.
