Introduction:

Infections caused by Mycoplasmas and Ureaplasmas may result in faults in the reproduction process and can be linked to female infertility.

Objective:

To determine the frequency of infection by Mycoplasma hominis and Ureaplasma spp. in women who attend to infertility consultations and if these are associated with a history of sexually transmitted infections and pelvic inflammatory disease, gynaecological procedures and symptoms of infections.

Methods:

A descriptive cross-sectional study was conducted to evaluate samples of endocervical swabs of 175 women between the ages of 20 to 45 years, from the Infertility consultation of the National Institute of Endocrinology, during June 2016 to January 2017. For the detection of urogenital mycoplasmas it was used the reagents kit Myco Well D-One. There were taken into account the ethical aspects and it was used the chi-square test to assess the statistical significance of the possible associations.

Results:

Of the 175 evaluated samples, 102 (58.1 %) showed the presence of infections, 65 of them corresponded to Ureaplasma spp (37.1%), 11 to Mycoplasma hominis (6.2 %), and 26 associations of Mycoplasma hominis and Ureaplasma spp (14.8 %). It was identified association between the detected infections and the presence of a history of sexually transmitted infections and pelvic inflammatory disease, but not with the gynaecological procedures and the symptoms of infections.

Conclusions:

The total frequency of infection was relatively high and the most prevalent specie was the Ureaplasma spp. The detected infections were associated with some of the factors studied.
