Increase in size of primary follicles including oocyte growth and granulosa and/or theca cell proliferation until more than one layer of granulosa cells is present (preantral follicle) as part of the primary follicle stage of oogenesis. The process, occurring above the cellular level, that is pertinent to the reproductive function of a multicellular organism. This includes the integrated processes at the level of tissues and organs. The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster. A reproductive process that is a step in the formation and maturation of an ovum or female gamete from a primordial female germ cell. The stage in oogenesis when a single layer of cuboidal follicle cells surrounds the oocyte. The oocyte nucleus is large.
