21 Ecografía 3D Raga et al. Hum Reprod 1999

22 Ecografía 3D “Aunque la eco 3D parece muy interesante, su utilidad clínica para predecir la gestación en FIV es LIMITADA” “Se ha comprobado que el volumen endometrial es ineficaz como predictor de la gestación tras FIV en la inmensa mayoría de los estudios” Alcázar et al. Reprod Biomed Endocrinol 2006

32 Endometrial Receptivity Array (ERA) - Resultados
INTERPRETACION DE RESULTADOS Receptivo (R): El perfil de expresión génica se corresponde a un endometrio receptivo normal Se recomienda hacer la transferencia en la ventana de implantación No Receptivo (NR): El perfil de expresión génica no se corresponde con una endometrio receptivo normal Se recomienda personalizar la ventana de implantación

35 Sildenafilo y endometrio
Estudio de cohortes One injection of corifollitropin alfa replaces 7 daily injections of rFSH during COS. The number of injections is reduced by about 70% compared with the long agonist protocol (from 35 to 10). In combination with the GnRH antagonist, this COS protocol can considerably reduce the treatment burden on patients. Additional daily rFSH after day 7 is to be determined by physician assessment. So what exactly is corifollitropin alfa? Let’s take a look at its molecular makeup on the next slide to see how it can perform as a sustained follicle stimulant. Sher and Fish. Fertil Steril 2002

46 Conclusiones Aún hoy, la ecografía bidimensional sigue siendo el método más sencillo y eficaz para evaluar un endometrio Las nuevas tecnologías no superan en capacidad predictiva a la ecografía bidimensional Ante un endometrio inadecuado, la mejor opción es congelar -ovocitos o embriones- y transferir cuando tengamos un endometrio adecuado One injection of corifollitropin alfa replaces 7 daily injections of rFSH during COS. The number of injections is reduced by about 70% compared with the long agonist protocol (from 35 to 10).

No existe ningún protocolo que haya demostrado una superioridad frente a otro: es importante que el paciente conozca que son protocolos que se encuentran en un entorno experimental
