RESUMEN
Antecedentes: las técnicas de reproducción asistida se utilizan cada vez con mayor frecuencia en el tratamiento de parejas con diagnóstico de infertilidad.
Objetivo: analizar el valor de la inseminación intrauterina en pacientes a quienes se realiza hiperestimulación ovárica controlada.
Material y métodos: estudio analítico, comparativo, retrospectivo y longitudinal de casos y controles. Se analizaron los ciclos de inseminación intrauterina (grupo I) y de coito programado (grupo II) de pacientes a quienes se efectuó hiperestimulación ovárica controlada, del 1 enero del 2004 al 31 diciembre del 2006. Se incluyeron pacientes infértiles entre 24 y 42 años (grupo I) y entre 23 y 36 años de edad (grupo II). Se analizaron: edad, tipo, causa y tiempo de infertilidad, densidad y movilidad espermática poscapacitación, así como espermatobioscopia directa para coito programado; número de folículos totales y maduros, grosor endometrial, tipo y dosis de gonadotropina y día de inseminación para el grupo I o día de inicio del coito para el grupo II. Los resultados se analizaron con los programas STATA 7.0 y SPSS 12.0.
Resultados: se analizaron 873 ciclos en 539 pacientes del grupo I y 246 ciclos en 138 pacientes del grupo II. La tasa de embarazo por ciclo fue de 13.1% (inseminación intrauterina) y de 5.2% (coito programado, p›0.05). La edad promedio para inseminación intrauterina y coito programado fue de 32.9 ± 3.5 y de 31.82 ± 2.7 años, respectivamente. Hubo diferencia significativa sólo en la densidad espermática entre ambos grupos.
Conclusiones: la inseminación intrauterina no parece tener ventaja sobre el coito programado en las tasas de embarazo de pacientes que han recibido hiperestimulación ovárica controlada.
