El plasma seminal de hombres vasectomizados como medio de diseminación de bacterias

Abstract

RESUMEN: Introducción: La vasectomía es un método de anticoncepción masculina definitiva que impide el paso de los espermatozoides a través de los conductos deferentes. Sin embargo, el plasma seminal aún posee la capacidad de transportar diferentes microorganismos a sus parejas. Objetivo: Determinar la presencia de ADN de C. trachomatis, N. gonorrhoeae, U. urealyticum, M. genitalium, M. hominis y el asilamiento por cultivo cuantitativo de bacterias aerobias en las muestras de semen de hombres vasectomizados. Métodos: Se tomaron muestras de semen de 10 voluntarios con vasectomía y 7 sin vasectomía asintomáticos para infecciones urogenitales que fueron colectadas y evaluadas según los lineamientos de la Organización Mundial de la Salud. A cada muestra de semen se le realizó cultivo cuantitativo en agar sangre, chocolate y MacConkey. Se realizó extracción de ADN mediante la técnica de fenol-cloroformo y detección del ADN de los microorganismos mediante la reacción en cadena de la polimerasa. Resultados: Se obtuvo crecimiento de algún microorganismo en las 10 muestras evaluadas, entre los cuales se encuentran Staphylococcus coagulasa negativa, Staphylococcus aureus, Streptococcus viridans y Pseudomona putida. Sólo se detectó ADN de U. urealyticum en 70 % de las muestras seminales provenientes de vasectomizados y en 57 % en los voluntarios. Conclusión: Los hombres con vasectomía pueden ser reservorios de microorganismos (inclusive microbiota) y de transportarlos hacia el tracto reproductivo femenino podría causar alteraciones importantes como infertilidad.

ABSTRACT: Introduction: Vasectomy is a definitive method of male contraception, which prevents the passage of sperm through the vas deferens. However, seminal plasma has the ability to transport different microorganisms. Objective: To determine the presence of DNA of C. trachomatis, N. gonorrhoeae, U. urealyticum, M. genitalium, M. hominis and the isolation by culture of aerobic bacteria in vasectomized semen samples. Materials and methods: Semen samples from 10 vasectomized volunteers and 7 non-vasectomized volunteers, and apparently healthy, were collected and evaluated according to the World Health Organization guidelines. Quantitative culture on blood agar, chocolate and MacConkey, DNA extraction using the phenol-chloroform technique and DNA detection from the microorganisms using the polymerase chain reaction technique was performed in each semen sample. Results: Some microorganism growth was obtained in the 10 vasectomized volunteers samples assessed. Some of them were Staphylococcus coagulase negative, Staphylococcus aureus, Streptococcus viridans, and Pseudomona putida. Only U. urealyticum DNA was detected in 70% of the seminal samples from vasectomized volunteers and in 57% in the volunteers. Conclusion: Vasectomized men can be reservoirs of microorganisms (including microbiota) and transport those microorganisms to the female reproductive tract, which could cause important alterations such as infertility.
