RESUMEN
Resumen Objetivo:
Determinar si la eliminación de espermatozoides positivos a marcadores tempranos de apoptosis en parejas con infertilidad inexplicable incrementa la tasa de nacidos vivos. Materiales ymétodos:
Ensayo piloto, con asignación al azar, controlado y triple ciego; y un estudio paralelo de dos grupos. Se incluyeron parejas con diagnóstico de infertilidad inexplicable que se asignaron en una proporción 11 al grupo A (método de capacitación espermática swim-up) o grupo B (método de capacitación espermática swim-up complementado con separación magnética de células activadas; magnetic-actived cell sorting; MACS). Posteriormente, a todas las muestras se les efectuó una inyección intracitoplasmática de espermatozoides, como técnica de fertilización. Por último, todos los embriones obtenidos se analizaron hasta la etapa de blastocisto y todas las transferencias se llevaron a cabo en la misma etapa.Resultados:
Se incluyeron 40 parejas y no se encontraron diferencias en la tasa de fertilización. Con la aplicación de MACS se obtiene mayor porcentaje de embriones de buena calidad en día 3 (90.3 vs 99.5%; p = 0.03) y en día 5 (77.3 vs 90.1%; p = < 0.0001) disminuyó el porcentaje de embriones arrestados (16.3 vs 7.9%; p = 0.01). Por último, las tasas de implantación (42.1 vs 57.1%), embarazo clínico (60 vs 80%) y nacidos vivos (55 vs 80%) aumentaron, sin diferencias estadísticamente significativas.Conclusiones:
La separación magnética de células activadas (MACS) en parejas con infertilidad inexplicable mejora el desarrollo embrionario. A pesar de no existir una diferencia significativa se observa una tendencia al incremento de embarazos clínicos y nacidos vivos.ABSTRACT
Abstract Objective:
To determine if the live births delivery rate with the eliminating sperm positive to early apoptotic events is higher in couples with unexplained infertility. Materials andmethods:
A pilot randomized controlled trialA pilot and triple-blinded; using a parallel study of two groups. We included a total of 40 couples with unexplained infertility assigned in a 11 proportion either to the group A (sperm training method swim-up) or to the group B (swim-up sperm training method supplemented with the use of "magnetic-actived cell sorting (MACS)"). Subsequently, all samples were submitted to intracytoplasmic sperm injection as a fertilization technique. Finally, all embryos obtained were analyzed until the blastocyst stage, and all the transfers were performed in the same stage.Results:
There are no differences in the fertilization rate; however, with the use of "magnetic-actived cell sorting" there is a higher percentage of good quality embryos on day 3 (90.3% vs 99.5%, p = 0.03) and day 5 (77.3% vs 90.1%, p = <0.0001). In addition, a decrease in the percentage of arrested embryos was demonstrated (16.3% vs 7.9%, p = 0.01). Finally, implantation (42.1% vs 57.1%), clinical pregnancy (60% vs 80%) and live birth rates (55% vs 80%) increased; however, no statistically significant differences were reported.Conclusions:
The use of "magnetic-actived cell sorting" in couples with unexplained infertility improves embryonic development. Although there is no significant difference, a trend is observed in relation to the increase in the number of clinical pregnancies and live births.
