oositleri
Oositleri, or oocytes in Turkish, are the female gametes involved in sexual reproduction. They develop in the ovaries through oogenesis and serve as the cell that, when fertilized, combines with a male gamete to form a zygote. In humans and many other mammals, oocytes arise during fetal development and are housed in ovarian follicles. At birth, females possess millions of primary oocytes, which decline to around a few hundred thousand by puberty and only a fraction reach ovulation during reproductive years.
During development, oocytes proceed through meiosis in distinct stages. Primary oocytes are formed and arrested in
Structure and composition are specialized for supporting early development. An oocyte is a relatively large cell
Clinical relevance includes maternal age-related declines in oocyte quality and increases in aneuploidy risk. Oocytes are
