Edad avanzada y Rejuvenecimiento

Las consecuencias del envejecimiento reproductivo se observan a diario en las clínicas de reproducción. Por esto, los investigadores de IVIRMA Global están trabajando para identificar los mecanismos que producen dicho envejecimiento.

Entre los proyectos, destacan:

cambios en el epigenoma relacionado con la edad
dinámicas de telómeros en gametos y sangre periférica
función mitocondrial en la preimplantación de embriones

El equipo científico también ha centrado sus investigaciones en identificar nuevas estrategias de tratamiento que puedan activar los folículos primordiales en pacientes que presenten un estado avanzado de envejecimiento reproductivo. Gracias a estas técnicas, se han conseguido embarazos en varios pacientes a los que previamente se les había diagnosticado un fallo ovárico prematuro
