Background:

The Mycoplasma hominis, Mycoplasma genitalium and Ureaplasma urealyticum are microorganisms associated with reproductive problems such as pelvic inflammatory disease in women and non-gonococcal urethritis in men. Alterations have been described in reproductive parameters and sperm morphology, rate of infertility and subfertility in man.

Objectives:

The aim of this study was to determine the incidence of Mycoplasma spp. and Ureaplasma spp. in patients Federal District (Mexico) and to evaluate the possible correlations with the semen analysis results.

Material and methods:

Retrospective study of 89 patients positive for Mycoplasma and Ureaplasma, we analyzed the results of the semen analysis and correlated statistically.

Results:

We obtained an increase in the diagnosis of these two microorganisms, by 15% in the first half of 2013 compared with 2012. Significant differences (P <0.001) in sperm morphology in patients positive to one of the two agents, the most frequent was the Ureaplasma.

Conclusions:

Mycoplasma and Ureaplasma are considered normal flora of the genitourinary tract, even so, the diagnosis should be performed in patients with a history of fertility and subfertility and should be considered when reporting morphological abnormalities and increased leukocyte count.
