OBJECTIVE:

To determine the prevalence of Ureaplasma urealyticum and Mycoplasma hominis in couples with infertility that participated in a high complexity protocol for assisted reproductive techniques.

MATERIALS AND METHODS:

Observational longitudinal, retrospective and descriptive study in which pathogens from positive samples were collected from infertile couples during a high complexity protocol for assisted reproductive techniques in the Mexican Center for Fertility Dr. Alberto Kably Ambe (Hospital Ángeles Lomas) between 2016 and 2019.

RESULTS:

A total of 172 infertile couples participated in the study. As a protocol previous to the in vitro fertilization, culture was performed in women and men. Of the vaginal culture, 65.1% were reported positive and Ureaplasma urealyticum predominated on 52.9% of them. While 47.7% of the semen culture were positive, and Mycoplasma hominis was on 34.9% of them.

CONCLUSIONS:

In infertile women, we reported a prevalence of 52.9% of Ureaplasma urealyticum and 15.1% of Mycoplasma hominis. For men, the proportion of positive cultures of Mycoplasma hominis was higher with 34.9%, while Ureaplasma urealyticum had a prevalence of 15.2%. Both microorganisms were present in the cultures of 5.8% of women and 7.6% of men.
