  • Investigación

  • Nuestros expertos están en la frontera de la investigación y son reconocidos internacionalmente por sus innovadores estudios científicos.

    La investigación científica tiene tanta importancia como la atención médica de nuestros pacientes. Por eso, nuestros tratamientos y especialistas están a la altura de los mejores centros de fertilidad internacionales.

    Tras los estudios pioneros de la Dra. Polak en hormonas y nuevas técnicas ligadas a la reproducción, se inició un camino científico que se ve reflejado continuamente en las mejores revistas científicas del mundo.

    En los laboratorios de CER, bajo la dirección científica de la Dra. Ester Polar de Fried, se llevan a cabo investigaciones en las siguientes líneas:

    - Células madres (stem cells).

    - Marcadores moleculares en espermatozoides.

    - Biología molecular ovocitaria.

    - Mecanismos de implantación.

    - Falla ovárica prematura.

    - Inmunología y reproducción.

    - Criopreservación de células y tejidos.

    - Mejoramiento de técnicas de fertilización.

    - Cáncer y hormonas.

    - Aspectos bioéticos de la salud reproductiva
