	Ootid - Wikipedia, the free encyclopedia
		An ootid is a female gametid, as opposed to a male spermatid.
		Two ootids are formed by meiosis of a secondary oocyte.

		The in vitro fertilization since 80 years is the most effective way of treatment infertility, especially in cases, when the woman has obstruction of uterine tubes or at the man in a sperm the low contents of spermatozoon or down stroke of their mobility is observed.
		The essence of procedure of in vitro fertilization (IVF) consists of reception from the ovaries of woman of mature ootids, fertilization by husband spermatozoon (or at the request of both spouses by semen of the donor), cultivation turned out embryos in an incubator within 48-72 hours, and transfer embryo in a uterus of patient.
		The disability of an ootid to a fertilization and division can be connected to difficulties of the procedure (damage of an ootid), and also with the quality of sex cells.

	Oocyte - Wikipedia, the free encyclopedia
		The egg may be expelled from the ovary in this condition, and in many species, including humans, the second meiotic division is not completed until the egg is fertilized by a sperm.
		The oocyte divides in meiosis II into one ootid and the second polar body.
		The secondary oocyte is the largest cell in the body, and in humans is just visible to the naked eye.

		Cell type in the ovary undergoing meiosis leading to polar body formation and eventually to an ootid (mature egg) theoretically.
		Mitotic and meiotic divisions and associated events by which the primordial germ cells in the female are transformed into ova.
		Haploid female gamete after shedding polar bodies; often the oocyte dies without ootid formation unless fertilization occurs.

	Dorlands Medical Dictionary
		The secondary oocyte (one in the period between the first and second maturation division) is derived from a primary oocyte shortly before ovulation by a division that splits off the first polar body.
		If fertilized, the secondary oocyte divides into an ootid and the second polar body; otherwise it perishes.
		In mammals, the second maturation division is not completed unless fertilization occurs; hence the ootid has male as well as female pronuclear (haploid) elements.

		(b) Ootid The cell characterized by the presence of the male and female pronuclei is termed an ootid (figs, l and 1-2).
		The cytoplasm of the ootid has a diameter of about 100 μm (Hamilton, 1946; Noyes et al., 1965); each of the pronuclei measures about 30 μm (Zamboni et al., 1966).
		Although "in most mammalian species, the male pronucleus has been reported to be larger than the female pronucleus," the converse has been found in one human specimen and, in two others, the pronuclei appeared to be of equal size (Zamboni, 1971).

		In humans only one of these, the secondary oocyte continues into the second meiotic division, the other product (called a polar body) has no further role.
		The secondary oocyte proceeds through the second meiotic division producing an Ootid and a second polar body, which is discarded.
		It is the ootid that differentiates into the mature female gamete; the Ovum.

	Gametogenesis Summary - Gametogenesis Information
		Another meiotic division results in the production of an ootid and yet another polar body (the eventual number of polar vies associated with an ovum may equal as many as three if the first sloughed off polar body undergoes a subsequent division.
		Cellular differentiation of the ootid yields an ovum ready for fertilization.
		In many cases, however, the last maturational processes are accelerated because in human females, meiosis II is usually completed after fertilization.

		Metabolic Cooperation Following Fusion of Starfish Ootid and Primary Oocyte Restores Meiotic-Phase-Promoting Activity -- Guerrier and Neant 83 (13): 4814 -- Proceedings of the National Academy of Sciences
		In the starfish Marthasterias glacialis, polyethylene glycol (PEG) homologous fused pairs consisting of two immature oocytes, blocked at the germinal vesicle stage, or two ootids, blocked at the female pronucleus stage, remain arrested at these specific stages, unless they are stimulated by the hormone 1-methyladenine.
		In contrast, heterologous pairs develop up to female pronucleus formation in the immature partner, indicating that maturation-promoting factor was formed under these conditions.

		Note the differences between oogenesis and spermatogenesis in that only one egg cell is produced during this process and not four.
		The other three cells form polar bodies which are absorbed and digested by the functional ootid.

		An oocyte or ovocyte is a female gametocyte that divides twice by mitosis and meiosis into two other oocytes or into two ootids.
		A primary oocyte is just a kind of initial oocyte that is formed by mitosis of an oogonium into two primary oocytes.
		Each primary oocyte forms by meiosis two secondary oocytes, and each secondary oocyte divides into one ootid.

		After the first meiotic division there is a secondary haploid cell that receives all of the cytoplasm and the first polar body that receives almost none of the cytoplasm.
		The second meiotic division also has an unequal division of cytoplasm resulting in a large, haploid, daughter cell known as the ootid and a second polar body.
		The polar bodies eventually degrade and the ovum results.
