摘要: Fueron descritas con detalles la histologia ovarica, las caracteristicas estructurales y ultra-estructurales de foliculogenesis del Didelphisalbiventris. Estudios recientes sugieren que mamiferos metaterios tienen un ciclo reproductivo inusual, pero existen pocas informaciones en relacion a vida reproductiva los marsupiales. A pesar el modelo zarigueya se parece al metaterio euterio muchos aspectos, analisis muestra algunos rasgos peculiares estructura ultra-estructura oocito, colocan disposicion nuevos datos biologia
