By definition it means, to recapitulate mammalian oogenesis and producing fertilizable oocytes in vitro.it is a complex process involving several different cell types, precise follicular cell-oocyte reciprocal interactions, a variety of nutrients and combinations of cytokines, and precise growth factors and hormones depending on the ...
An oocyte (/ ˈ oʊ ə s aɪ t /, oöcyte, or ovocyte is a female gametocyte or germ cell involved in reproduction.In other words, it is an immature ovum, or egg cell.An oocyte is produced in a female fetus in the ovary during female gametogenesis.
The dictyate or dictyotene [1] is a prolonged resting phase in oogenesis.It occurs in the stage of meiotic prophase I [2] in ootidogenesis.It starts late in fetal life [2] and is terminated shortly before ovulation by the LH surge. [3]
oogenesis: oophor(o)-of or pertaining to the woman's (ovary) Neoclassical Greek ᾠοφόρον (ōiophóron), ovary, egg-bearing oophorectomy: ophthalm(o)-of or pertaining to the (eye) Greek ὀφθαλμός (ophthalmós), the eye ophthalmology: opistho-back, behind, rear [8] Greek ὄπῐσθεν (ópisthen), behind, at the back ...
Oogenesis is the formation of a cell who will produce one ovum and three polar bodies. [10] Oogenesis begins in the female embryo with the production of oogonia from primordial germ cells. Like spermatogenesis, the primordial germ cell undergo mitotic division to form the cells that will later undergo meiosis, but will be halted at the prophase ...
Gametogenesis, the development of diploid germ cells into either haploid eggs or sperm (respectively oogenesis and spermatogenesis) is different for each species but the general stages are similar. Oogenesis and spermatogenesis have many features in common, they both involve: Meiosis; Extensive morphological differentiation

Oogenesis, the process of female gamete formation in animals, involves meiosis (including meiotic recombination) of a diploid primary oocyte to produce a haploid ovum. Spermatogenesis, the process of male gamete formation in animals, involves meiosis in a diploid primary spermatocyte to produce haploid spermatozoa. In animals, ova are produced ...
