LAUSR

espanolExiste un alto numero de personas afectadas por infertilidad que requieren de tecnicas de reproduccion asistida. Por ello, el objetivo de esta revision ha sido analizar la efectividad de las intervenciones llevadas a cabo en dichas tecnicas. Se realizo una revision sistematica, por pares, en doce bases de datos. Los criterios de inclusion fueron: ensayos clinicos aleatorizados, publicados entre 2011 y 2016, y con una puntuacion mayor que dos en la escala Jadad. Las intervenciones farmacologicas efectivas encontradas fueron la administracion de hormonas: gonadotropina corionica humana intrauterina, gonadotrofina y dehidroepiandrosterona, y de metformina. Se localizo una intervencion quirurgica efectiva, raspado endometrial. No se hallo ninguna intervencion no farmacologica efectiva. Existe una heterogeneidad tanto de intervenciones incluidas en las tecnicas de reproduccion asistida, como de criterios para medir efectividad (tasa de embarazo, tasa de nacidos vivos o tasa de implantacion), siendo necesaria una unificacion de criterios. EnglishThere are a high number of people affected by infertility who require assisted reproduction techniques. For this reason the aim of this review was to analyze the effectiveness of the interventions carried out using these techniques. A systematic peer review was performed on twelve databases. Inclusion criteria were: randomized clinical trials, published between 2011 and 2016, and with a score greater than two on the Jadad scale. The pharmacological interventions that proved effective were the administration of hormones, intrauterine human chorionic gonadotropin, gonadotrophin and dehydroepiandrosterone, and metformin. An effective surgical intervention, endometrial scratching, was identified. No effective non-pharmacological interventions were found. Assisted reproduction techniques show heterogeneity in both the interventions included and effectiveness criteria (pregnancy rate, live birth rate or implantation rate), which makes a unification of criteria necessary.
