El trabajo muestra los resultados en FIV de la utilización de ovocitos MI madurados in vitro procedentes de ciclos estimulados

UTILIDAD CLÍNICA DE OVOCITOS MI MADURADOS IN VITRO

Los ovocitos MI procedentes de ciclos estimulados, pueden ser madurados y fecundados dando lugar a un niño vivo y sano. Sin embargo, el desarrollo de éstos es menor que el de los ovocitos MII pertenecientes a la misma cohorte. Por otra parte, los ovocitos MI necesitan entre 2 y 6 horas de cultivo tras la extrusión del primer corpúsculo polar para completar su maduración.
