n.
A diploid cell from which an egg or ovum develops by meiosis. A primary oocyte divides to produce a polar body and a secondary oocyte, which divides again to produce the ovum and another polar body.

(ˈəʊəˌsaɪt)
n
(Biology) an immature female germ cell that gives rise to an ovum after two meiotic divisions

However, many such patients are reluctant to accept a planned Oocyte Donation (OD) but prefer to keep trying with the stimulation of their own ovaries, because they hope that the "next stimulation will be the good one".
The researchers from the Goethe University Frankfurt deciphered the mechanism leading to premature loss of the oocyte pool caused by treatment with chemotherapy.
Cryopreservation of oocyte can be helpful in fertility preservation and development of assisted reproductive technology (Chen, 1986; van Uem et al., 1987).
Then after ovulation induction using the antagonist protocol the response to ovulation induction was determined by number of follicles restored (number of follicles produced as a result of ovarian stimaulation), quality of oocytes retrieved was noted (analysis of various aspects of oocyte morphology, cytoplasm, zona pellucid and polar body via conventional phase contrast microscoy had generated a criteria of good, moderate and bad quality oocytes), also the oocytes fertilized and inseminated were noted.
Mammalian oocyte maturation involves nuclear and cytoplasmic maturation, which are essential for successful fertilization and embryonic development [15].
Each slide was digitalized at high resolution (600 dpi; 40x) and processed in triplicate with Image-Pro Premier 2D version 9.2 for calculating total area (A) and theoretical mean diameter (TD) of each oocyte type to characterize detailed stages of oogenesis.

The germinal vesicle and the cytoplasmic organelles of the oocyte were disintegrated.
The story of in vitro fertilization (IVF) began with immature oocytes from unstimulated cycles and finally succeeded with the birth of Louise Brown in 1978 (1); however, the roots of studies about immature oocytes and in vitro oocyte maturation (IVM) go back to the 1930s (2).
Lead author of the research, Dr Nancy Nader, research associate in physiology and biophysics at WCM-Q, explained:"The role of the hormone progesterone in turning immature oocytes (ovarian cells) into mature eggs, in a process known as 'oocyte maturation' that prepares the cell for fertilization, is well known.
