Mycoplasma infection and infertility.

Area of Science:

• Reproductive Medicine
• Microbiology
• Infectious Diseases

Background:

• Genital mycoplasmas, such as Ureaplasma urealyticum and Mycoplasma hominis, are frequently detected in the female reproductive tract.
• The role of these microorganisms in female infertility remains a subject of investigation.

Purpose of the Study:

• To investigate the association between genital mycoplasma infection and female infertility.
• To determine the prevalence of Ureaplasma urealyticum and Mycoplasma hominis in infertile, pregnant, and nonpregnant women.

Main Methods:

• Cervical samples were collected from three groups of women: infertile, normal pregnant, and normal nonpregnant.
• Mycoplasma cultures were performed to identify Ureaplasma urealyticum and Mycoplasma hominis.

Main Results:

• Ureaplasma urealyticum was detected in 63% of infertile women, 68% of pregnant women, and 62% of nonpregnant women.
• Mycoplasma hominis prevalence was lower, with rates of 10%, 11%, and 6% in the respective groups.
• No statistically significant differences in isolation rates of either mycoplasma species were observed among the three groups.
• Over a 12-month follow-up, 27.5% of untreated infertile women conceived, including 28% of those with Ureaplasma urealyticum.

Conclusions:

• Female genital infections with Ureaplasma urealyticum are highly prevalent.
• The data suggest that Ureaplasma urealyticum infection is not directly associated with female infertility.
• Further research may be needed to explore potential subtle roles or co-factors in reproductive health.
