Similarly increased congenital anomaly rates after intrauterine insemination and IVF technologies: a retrospective cohort study

Abstract: The risk of major birth defects in singletons conceived through IUI was increased over naturally conceived singletons. This risk was no different from that observed after IVFT.

“…The percentage of malformations observed in newborns in our registry was 0.83 %, which is similar to the rate of malformations observed in the latest published National Spanish Report (1.19 %) [2]. More recently, the prevalence of major congenital anomalies recorded in Europe was 2.4 % [7], coinciding with a retrospective cohort study that found a similar prevalence of major congenital anomalies in singletons (2.1 %) and twins (2.4 %) from natural conceptions [31]. The percentage of malformations observed in our study is similar to that reported by recent authors.…”

“…The percentage of malformations observed in our study is similar to that reported by recent authors. In this sense, the metaanalysis by Rimm et al [30] concludes that ART does not increase the risk of major malformation as much as previously reported by others [18,31]. Furthermore, The Spanish Collaborative Study of Congenital Malformations (ECEMC) has published an annual report since 1980.…”

“…Si bien existen desde 1995 dudas sobre la seguridad de los procedimientos, hasta muy recientemente han obviado tan grave asunto con la falacia de que no está clara la causa en cuanto que no se conoce -se decía-qué proporción del daño se debe a la situación de los gametos de los progenitores y qué proporción se debe a las técnicas en sí mismas. Resumiendo los numerosos estudios: a) La inseminación intrauterina conlleva tantos riesgos para la descendencia como la fecundación in vitro o la inyección de un espermatozoide al óvulo (Sagot et al, 2012); b) Esta última es más perjudicial que la convencional; c) El riesgo de nacer con algún tipo de defecto es mayor que cuando son engendrados (Davies, et al, 2012;Pandey et al, 2012); d) Se generan síndromes raros (Fortunato & Tosti, 2011) y alteraciones que aparecen a largo plazo, causadas por la exposición del embrión en los primeros días de vida a un entorno adverso (Scherrer, et al, 2012).…”

“…Die Herkunft der Spermien oder die Schwere einer männlichen Subfertilität haben keinen Einfluss. Untersuchungen dokumentierten, dass auch kein Unterschied zwischen einer IVF und einer intrauterinen Insemination besteht [15]. Zur Behandlung mit Clomifen oder Gonadotropinen existieren bis heute keine verlässlichen Daten.…”
