Este protocolo describe metodologías para establecer un modelo de implantación embrionaria in vitro simple y eficiente para evaluar las moléculas relevantes que afectan el proceso de implantación embrionaria.

La implantación del embrión, el paso inicial de un embarazo exitoso, es crucial para comprender su base biológica y abordar los desafíos de la infertilidad. El objetivo de este estudio es establecer una plataforma consistente para analizar las interacciones entre el endometrio embrionario y el endometrio en condiciones controladas. Sobre la base de este modelo in vitro, encontramos que las concentraciones ultra altas de estrógeno reducen significativamente el riesgo de implantación del embrión, mientras que la suplementación con progesterona podría aliviar de manera dependiente estos efectos negativos.

Este estudio ofrece nuevos conocimientos y estrategias terapéuticas para mejorar los riesgos de embarazo en la transferencia de embriones frescos durante la estimulación ovárica controlada para la FIV. En comparación con el sistema de cultivo tridimensional, este modelo in vitro ofrece una plataforma simple, rápida y rentable que se puede establecer en la mayoría de los laboratorios, y exhibe una alta reproducibilidad y confiabilidad, lo que lo convierte en una herramienta ventajosa para la investigación y el desarrollo en el campo de la biología reproductiva.
